Chevy Traverse 3.6L DOHC Repair Information
Chevy Traverse 3.6L DOHC Engine Repair Information
Here you will find information on installing the Chevy 3.6L DOHC engine. In this guide we will start on the inside of the engine including the crankshaft, connecting rods and piston ring installation and then move outward to the pulley system. Along the way, correct procedures and torque specifications are given to aid in assembling the engine. Feel free to start from the beginning and work your way out or jump to your current position in the engine to learn what you need.
Installation of the crankshaft main covers
Chevy Traverse 3.6L Main Cover Torque Specifications (Internal): 15 ft-lbs + 80°
Chevy Traverse 3.6L Main Cap Torque Specifications (Outside): 10 ft-lbs + 110°
Chevy Traverse 3.6L Main Cover Torque Specifications (Side): 22 ft-lbs + 60°
The main bearing caps on the 3.6 liter engine block should be inspected for defects or defects prior to installation. Be sure to lubricate the bearing surfaces before installation. After preparation, you can put the caps on the crankshaft and start tightening the bolts in a multi-step process. There are 3 different torque sets for the main cover bolts on this engine. These specifications are divided into the inner screws, outer screws and the side screws. The inner bolts are the ones farthest from the center of the engine. The outer bolts are the ones farthest from the center of the engine and the side bolts are the bolts that are fully tightened from the outside of the engine. The inner main bearing bolts can be rotated to 15 ft-lbs and then rotated 80 degrees. The outboard main bearing bolts can be rotated to 10 ft-lbs and then rotated 110 degrees. Finally, the side screws can be rotated to 22 ft-lbs and then rotated 60 degrees. Be sure to go through each bolt at each stage of the tightening sequence. Once you’re done, you should be able to move on to the rest of the motor.
Installation of piston and connecting rod
Chevy Traverse 3.6L Connecting Rods Torque Specifications: 18 ft-lbs + 110°
To assemble the pistons and connecting rods, you must first install the piston rings in each piston. Be careful not to stretch or break the rings during installation. Make sure you put the correct rings in the correct positions, this can be determined from the instructions that come with the new rings. Each ring manufacturer is different, so be sure to look for your specific rings. After installing the rings you can now insert the connecting rod bearings into the end caps and lubricate them with oil or lithium grease. The piston can now be lowered into the cylinder, making sure the dot or mark is facing the front of the engine and being careful not to scratch the cylinder. Once installed, you can align the connecting rod caps with the correct rods and begin tightening the connecting rod bolts to 18 ft-lbs and then an additional 110-degree turn for each bolt. After everyone is done, turn the crank to make sure all the pistons move in and out of their cylinders smoothly and nothing is binding.
Installation of the oil pump
Chevy Traverse 3.6L Oil Pump Bolts Torque: 18 ft-lbs
Chevy Traverse 3.6L Oil Pump Cover Bolts Torque: 8 ft-lbs
When installing the oil pump, be sure to use the correct sealant around the pump base if necessary to ensure oil pressure does not drop due to leakage. Both surfaces should be cleaned and prepared prior to installation. After preparing the mating surfaces, carefully install the oil pump onto the front end of the engine by aligning the crankshaft through the center of the oil pump bore. There should be flat ends of the crank that line up with the pump. Once in place, you can finger tighten the oil pump mounting bolts. These bolts are the larger of the pump bolts as shown in the picture. After hand tightening, you can tighten the 3 hex head screws to 18 ft-lbs. From here you can proceed to the timing chain system installation or the next part of your build.
Installation of the cylinder head
Chevy Traverse 3.6L Cylinder Head Torque Specifications (M11): 22 ft-lbs + 150°
Chevy Traverse 3.6L Cylinder Head Torque Specifications (M8): 11 ft-lbs + 75°
The first thing to do when installing cylinder heads is to ensure that both the block and head surfaces are completely free of dust, oil and any debris. The next thing you need to do is set the camshafts in their correct positions to prevent valves from hitting the pistons during installation and tightening of the head bolts. Likewise you need to set the pistons to their correct positions, usually this means setting the #1 piston to top dead center or top dead center. Once everything is ready you can mount the head gasket onto the engine block by aligning the alignment pins. Something I usually do is spray the head gasket with some Permatex motor copper spray you can find. This will ensure that any gaps that may exist between the two surfaces are filled with the spray. It also helps transfer heat between the two metals. With the gasket in place, you can place the cylinder head on the gasket and block. Have someone help you with this process if needed as the head can be heavy and you don’t want to scratch or drop anything! Once the head has been placed you should start installing the head screws to make sure it doesn’t move. Be sure to buy new head bolts as many manufacturers use TTY or Torque-to-Yield head bolts, which means they stretch when tightened and cannot be used twice. Also, be sure to lubricate the bolts with clean engine oil before installing them in the head. Once all of the head bolts are installed and finger tight you can begin tightening, almost all head bolts have a multi-step tightening process. There are 2 different size head bolts on this 3.6 liter engine, the M11 and the M8, the M8 being the smaller of the 2. Make sure you use all new head bolts as these are TTY bolts, which can only be used once as they stretch during installation. The M11 socket head bolts are torqued to 22 ft-lbs and then rotated 150 degrees. The smaller M8 socket head bolts are torqued to 11 ft-lbs and then 75 degrees of rotation. Be sure to go through each screw at each step before moving on to the next value. Once complete you can proceed to install the camshafts and timing chain system.
Installation of timing chain and camshaft
Chevy Traverse 3.6L Cam Sprocket Torque Specification: 43 ft-lbs
Chevy Traverse 3.6L idler pinion torque specification: 43 ft-lbs
Chevy Traverse 3.6L Camshaft Bearing Cap Bolts Torque: 8 ft-lbs
Chevy Traverse 3.6L Timing Chain Guide Torque Specification: 18 ft-lbs
Chevy Traverse 3.6L Timing Chain Tensioner Torque Specification: 18 ft-lbs
Chevy Traverse 3.6L Crankshaft Position Sensor Torque Specification: 8 ft-lbs
In the Chevy 3.6 DOHC engine, the timing system is operated through the use of 3 different timing chains. 2 of the chains run from idler sprockets to each cylinder head to run the VVT camshaft sprockets. The third timing chain from the oil pump or crankshaft sprocket to the 2 idler gears. This timing chain system is quite complex so be sure to study the image provided and if you are unfamiliar with engine timing then research further. Before installing the control system, make sure to install the cylinder heads and tighten them properly by following the steps above. Once the heads are installed you can install the camshafts in the correct locations. Each cylinder head has an intake and an exhaust camshaft, marked I and E. The intake camshafts are located on the innermost side of the engine, with the sprocket side facing the front of the engine, or where the timing chain and oil pump run. The exhaust camshafts go outwards in the same way. Make sure all rocker arms and hydraulic valves are in place and stay in place when installing and tightening the camshafts. The camshafts are secured with bearing caps which should be installed greased and torqued to 8 ft-lbs. Once all 4 cams are installed and torqued, you can install the cam sprockets or VVT actuators and torque to 43 ft-lbs. Be sure to hold the camshafts by the flat ends with a large wrench while you tighten them, otherwise they will just spin. Once tightened, you can install the idler sprockets and tighten to 43 ft-lbs. After installing the oil pump, the crankshaft gear is simply pushed onto the crankshaft and aligned using a woodruff key. From here we can install the timing chain on the right side of the engine and line up the yellow link with the dot on the sprockets. On the idler gear, the painted link should be visible through the hole. Now mount the timing chain tensioner guide and the timing chain guide and hand-tighten the screws. The tensioner can then be installed, they are different for each side so be sure to use the correct one by lining up the oil hole with the tensioner oil hole. Hand tighten the chain tensioner, then torque the tensioner and guide bolts to 18 ft-lbs. Moving down, we can install the center timing chain that goes from the crank to the idler wheels. This chain aligns with the painted marks on the chain with small arrow marks. The right hand side guide for this chain comes preinstalled on the oil pump but if removed can be reinstalled once the chain is in place and torqued to 18 ft-lbs. The tensioner side of the center chain system and the other guide can also be pulled down to 18 ft-lbs. Finally the final timing chain can be installed following the same steps as the chain on the right by aligning the painted marks and dots and then installing the tensioner and guides. After installation, be sure to check each painted mark on each chain and then loosen the tensioners and ensure each chain is seated firmly on its sprocket teeth. From here we can move on to the timing gear cover and valve covers.
Installing the timing case cover
Chevy Traverse 3.6L Timing Case Torque Specifications: 18 ft-lbs
The 3.6 liter engine timing case cover is used to cover the inside of the engine and contain large amounts of oil. For this reason, I recommend using some silicone sealant along with a new gasket during installation. Be sure to clean all metal surfaces before installing and applying the silicone to the metal. With everything ready to install, be sure to check your timing and engine internals before installing the cover. Another tip is to lubricate the crankshaft oil seal with some oil so that it fits better. If everything is in order, place the cover on the engine block and start hand tightening the screws. Once all of the bolts are finger tight and you wait the recommended time your sealant manufacturer will tell you, you can torque the timing cover bolts to 18 ft-lbs. Be sure to tighten them in a criss-cross pattern from one side of the cover to the other rather than tightening them all one at a time as this can cause leakage.
Installation of the oil pan
Chevy Traverse 3.6L Oil Pan Torque Specs: 18 ft-lbs
Chevy Traverse 3.6L Pan Side Bolts Torque Specifications: 37 ft-lbs
Chevy Traverse 3.6L Oil Drain Plug Torque Specifications: 18 ft-lbs
Similar to the timing case cover on the 3.6 liter engine, the oil pan plays an important role in keeping the engine oil in the engine. For this reason, I recommend using a new gasket and some silicone sealant when installing. Using the same technique as before with the cover, clean the surfaces of both the oil pan and engine block and then install the new gasket onto the block and then follow with some silicone sealant. Be sure to follow your sealant’s directions to ensure you get the best seal out of your application. Pan bolt torque is 18 ft-lbs in a cross pattern design. The oil pan side bolts are torqued to 37 ft-lbs. Along with the pan is the oil pan drain plug, this is removed and reinstalled fairly frequently and can be pulled down to 18 ft-lbs.
Installing the valve covers
Chevy Traverse 3.6L Rocker Cover Torque Specs: 8 ft-lbs
Installing the valve cover is fairly easy, there are rubber grommets for each bolt hole and a silicone gasket to prevent oil from leaking out of the engine. It is recommended to replace both the gaskets and the gaskets, although you can reuse them if they are in good condition. If you intend to reuse them I would use some silicone sealant along with the silicone gasket to ensure it doesn’t leak. The valve cover bolts are tightened criss-cross to 106 in-lbs or approximately 8 ft-lbs. Be careful not to overlook any screws to avoid oil spilling onto the exhaust pipes and causing a lot of smoke.
Installation of intake manifold and fuel rail
Chevy Traverse 3.6L Intake Manifold Torque Specs: 18 ft-lbs
Chevy Traverse 3.6L Ignition Coils Torque Specification: 8 ft-lbs
Chevy Traverse 3.6L Spark Plug Torque Specifications: 13 ft-lbs
Chevy Traverse 3.6L Throttle Body Torque Specs: 8 ft-lbs
When installing the intake manifold, you should ensure that you have cleaned all surfaces and the intake holes before placing the manifold in position. After cleaning, you can place the intake manifold gaskets on the alignment pins. If you want you can also put a little sealant on the gaskets to make sure there are no leaks. With the gaskets in place you can now place the manifold on top of the gaskets and begin installing the bolts. The intake manifold bolts should be tightened to 18 ft-lbs. The ignition coils can be torqued to 8 ft-lbs and the spark plugs themselves to 13 ft-lbs. Be careful not to over tighten these as they can break and cause big problems. When installing the throttle body, make sure all gaskets are in good condition and are holding a seal as you don’t want any gas fumes escaping around the engine. If everything looks good, you can tighten the throttle body bolts to 8 ft-lbs.
Installing the exhaust manifold
Chevy Traverse 3.6L Exhaust Manifold Torque Spec: 15 ft-lbs
Chevy Traverse 3.6L Exhaust Pipe Torque Specifications: 18 ft-lbs
Chevy Traverse 3.6L EGR Pipes Torque Specs: 15 ft-lbs
The exhaust manifold can be installed by cleaning the surface areas on both the head and the manifold itself, then using and installing the exhaust manifold gasket. Once the gasket is in place you can place the manifold on the heads and start pulling it down to 15 ft-lbs. I always use some Permatex copper spray on the exhaust manifold gaskets to make sure I don’t end up with any exhaust leaks when I’m done. When installing the engine on the vehicle or when it is already on the vehicle, the torque for the exhaust manifold to the tailpipes or catalytic converter is 18 ft-lbs. The EGR system consists of a series of tubes that run from the manifold to the head. The EGR tubes on this engine can be torqued to 15 ft-lbs.
Installation of water pump and thermostat
Chevy Traverse 3.6L Water Pump Torque Specs: 8 ft-lbs
Chevy Traverse 3.6L Water Pump Pulley Torque Specs: 8 ft-lbs
The water pump on the Chevy 3.6 liter engine should be installed with a new gasket and, if desired, some silicone sealant to prevent leaks. Be sure to clean both metal surfaces before installing the pump. After preparation, the pump can be placed in position and then tightened. On this engine, the water pump is torqued to 8 ft-lbs to the engine block. Be sure to cross-tighten the screws to ensure there are no leaks. The old water pump bolts are TTY and should not be reused more than once. The water pump pulley can then be tightened to 8 ft-lbs of torque on the pump itself.
Installing the front dress and pulley belt
Chevy Traverse 3.6L Crankshaft Pulley Torque Specifications: 74 ft-lbs + 150°
Chevy Traverse 3.6L Idler Pulley Bolt Torque: 43 ft-lbs
Chevy Traverse 3.6L Drive Belt Tensioner Bolt Torque Specifications: 43 ft-lbs
Chevy Traverse 3.6L Motor Mount to Motor Torque Specifications: 59 ft-lbs
Chevy Traverse 3.6L Motor Mount to Frame Torque Specifications: 35 ft-lbs
Chevy Traverse 3.6L Power Steering Pump Torque Specifications: 37 ft-lbs
Chevy Traverse 3.6L Alternator Bracket Torque Specifications: 37 ft-lbs
Chevy Traverse 3.6L A/C Compressor Bolt Torque Specifications (Rear): 37 ft-lbs
Chevy Traverse 3.6L A/C Compressor Bolt Torque Specifications (Front): 17 ft-lbs
Most of what remains on the engine is just placing and tightening items such as pulleys, belt tensioner, throttle body, oil filter neck, crankshaft pulley and engine mounts. If the parts have a gasket and will hold either oil or coolant in the engine, you’re welcome to add some sealant along with the gasket. Always be sure to inspect your seals and replace them if they show any deterioration or imperfections. For the belt system, the crankshaft pulley is tightened to 74 ft-lbs and then an additional 150 degrees of rotation. This is extremely tight so I recommend somehow holding the crankshaft during the tightening process. The drive belt tensioner bolt can be tightened to 43 ft-lbs and the idler bolt can be tightened to 43 ft-lbs. When installing, make sure they both spin easily and if they don’t, replace them with new ones as the bearings can go bad. The engine mount can be installed onto the engine block if not already done, the torque for the mount on the block is 59 ft-lbs and then when the mount is installed on the vehicle or frame it can be tightened to 35 ft-lbs . Finally, with a good gasket and some extra sealant, the throttle body can be installed in a criss-cross pattern with 7 ft-lbs on top of the intake manifold. To mount the belt, you can use a tool to bring the tensioner into its spring-loaded state and mount the belt as shown in the picture. The power steering pump should be torqued to 25 ft-lbs. The alternator can be torqued up to 37 ft-lbs.

What is the best RTV for a 3.6L timing case cover? The OEM RTV blew due to poor PCV valve design. The PCV has been changed. The previous owners ran it on maximum oil consumption and clogged the right side. The 3.6 gets new camshaft adjusters, timing chains, VVT magnets and gaskets. I fix anything that needs replacing while it’s apart. I’m not sure about the injectors. I can do that later if needed. The pre-DI design inlet is easy to detach.

Thank you shepherd. It is metal to metal contact. GM didn’t make a gasket for its design. I’m not even sure where the RTV is going. Components have gaskets or gaskets. Cover to Block is all RTV. I need to find an image with a marked cover or RTV bead as an example.

For real? who has one I’m interested! It would save me a lot of time and worry about future leaks. A friend just bought a 3.6 CTS Caddy so I will be making his in the future. At least this one is pointing forward. I will modify the PCV and add an oil catch can.
Out of curiosity, how many turns does it take for the alignment marks to be true again? Do they straighten out? I’m not worried I will be using cam lock plates for the cam phaser replacement.

paulo57509,
My parts bin has all these gaskets ready. I meant a one or multi piece gasket kit for the timing case cover itself. It’s huge. RTV is used to seal it. Due to the insufficient PCV system, the RTV will be blown out. Blowing out causes oil leaks.
More parts are on order. The harmonic balance bolt is a one-time use type. It will be replaced. The water pump, while not old, will be upgraded to a metal impeller if this is not the case. I can even upgrade it to a high flow pump.
A guy doing the job took both wheels off to reach into the engine bay. He lowered the entire front end to rest on a 3 ton jack. No elevator, just silence. The rotors are 3-5 inches off the ground. The engine compartment and the screws are more easily accessible. As a backup I can use 4X4 blocks under the rotors.

Ok, I’m finally tearing down the Acadia 3.6. Only the rear power steering bolt remains. Once outside, the cover may come off. The right bank is much dirtier than the left. Is there a way to seal the spark plug tubes? Oil was found in the 3rd and 5th cylinders. 5 is the worst. Looking at the valve cover it doesn’t seem to be leaking from there into the hose.
I have cam-lock tools for installing chain and camshaft adjusters. I also have a flexplate locking tool for better freedom of movement. Since the starter is off to refresh I use a tool to hold the crank in place. The tools will help hold the motor while the harmonic balancer screw is removed. Found information, it’s really tight. A 24″ plus pry bar may be needed.
How long should the RTV cure before installing the cover? After it is turned on, another tag is used to cure before reassembling. I have a lot of parts to clean and paint.
Appendix:
Dirty right bank. Dirty right bank.

All seals are replaced. Timing cover solenoids and sensors are replaced. Any preventative maintenance part that I can replace will be replaced or cleaned. I will post a photo of the back of the control case. It’s obvious where oil leaked.

Help! My tool helper got a plate out of the way. I found it today. It’s a black plate that goes behind the blander. 5 control cover screws are used. Can I omit the black plate? Everything is dressed to specification. RTV has dried for 3 days. Nothing screwed on the plate. I see no use for it. It has a slotted hole on the power steering pump side. Seems more like a cover than anything. Should I omit it or wear it? I have to take off the balancer. I used a new bolt and new timing cover bolts.
