Bleeding a radiator removes excess or trapped air from the system. Air can’t be heated like water, so that’s usually why a radiator feels cold at the top.

The air rises and gets stuck, so the hot water can only reach about halfway up the radiator. This is very inefficient and can help explain why you have cold spots or drafts in your home, or generally wonder why a room feels a little chilly.

Bleeding your radiators is not the same as flushing a system – you are not removing the water, just letting the air out.

It’s a process that only takes a few minutes, but could improve the efficiency of your heating system and make your home a little warmer.

Yes, it is perfectly normal for water to escape when you bleed a radiator.

You will likely notice a few drips coming out when you initially turn the bleed screw counter-clockwise. And water would pour out once the air was deflated when the valve was supposed to be fully opened.

However, a full opening of the valve should be avoided. For a more in-depth look at radiator bleeding best practices, take a look at our Advice Center guide, Bleeding a Radiator.

My car is overheating. I changed the thermostat and water pump and put a new hose on it. The car ran fine for about a week and started overheating again. The coolant is full and the engine is no longer taking in water. I was advised to do a radiator flush next. Could my engine be clogged?

My car has 225000 miles.

My car has an automatic transmission.

There are some engine coolants that are designed to be mixed with water before being poured into the cooling system, but you can’t just use whatever you want. Eventually, due to the mineral content of water, minerals accumulate in your radiator, plumbing, and water pump.

Can you do a coolant flush with tap water? Tap water is fine as long as it is used properly. Disconnect the lower right hose from the system once you’re done and use it to flush as often as possible. If you must flush, be sure to do so as thoroughly as possible. The hose must be reconnected and the radiator filled.

What happens if you use tap water in the coolant? Is it recommended to use regular tap water with coolant and water? In the case of distilled water, distilled water is preferable to deionized water. Because tap water contains minerals that can deform deposits in the radiator and cooling system passages, it is important to drink bottled water.

What happens if you don’t use distilled water in the coolant? You can find more videos on YouTube as it chemically removes electrons from cooling system components and causes extreme damage that can lead to system failure.

Can you use tap water to flush the cooling system? If you have it, you can get your drinking water from the tap. Flush the system with the hose as much as possible by disconnecting the bottom hose. You should make the best of it. Fill the radiator halfway and turn on the hose.

Can you fill tap water in the coolant tank? There is no way to combine tap water and engine coolant in one vehicle. It is possible to use distilled water but not ideal. The best option is to drink a glass of warm water.

Can you put flush water in your coolant? Pure water can theoretically be used in your cooling system, but it is not recommended as a long-term solution in very cold weather. The problem with using water in cooling systems is that water freezes at C.

Can I use bottled water as a coolant? If your radiator is lacking coolant, consider topping it up with quality water from your local garden supplier. It would be preferable if the water was distilled. You can also buy bottled water or tap water to drink.

A car’s cooling system is based on high-quality coolant/antifreeze that has been tested in extreme temperatures and is free of dirt and particles that could impair performance or corrode engine components. This means it is important to drain and refill the cooling system at the right time or at mileage intervals to ensure optimal cooling performance and engine health.

If your coolant is getting old, your car has been driven many miles, or you have noticed a change in the color and consistency of the coolant/antifreeze in the reservoir, it is time to flush the cooling system and replace the old fluid. Before you start thinking about how much that’s going to cost in a workshop, we’re here to give you practical guides and advice on how to flush the cooling system yourself – using Prestone Cooling System Flush to get professional results without the expense.

Do I need to flush my car’s cooling system?

In a word, probably. Over time, poor quality coolant/antifreeze can pick up particles from the engine environment and cause corrosion that can lead to leaks and other costly repairs. Removing these deposits and restoring the protection against corrosion is vital to a safe and fully functional cooling system, especially if you want to avoid unexpected failures due to overheating, leaks or engine damage.

How often should I flush the cooling system and radiator?

Mechanics and automakers all give conflicting advice on how often a cooling system should be flushed. The correct interval depends on a number of factors – from the age and condition of your car, to the type of driving you do most, to the variety of coolant/antifreeze in the reservoir.

If you are unsure when to flush your car’s cooling system, consult your vehicle manual or the coolant/antifreeze manufacturer’s instructions.

If your cooling system is running on Prestone’s new coolant/antifreeze, you’re good for 10 years or 300,000 miles.

How can I tell when my cooling system needs to be flushed?

The easiest way to tell when the cooling system needs a flush is to regularly check the condition of the coolant/antifreeze in the reservoir. Open the container and check the color and consistency of the liquid. If it’s cloudy, cloudy, or thick, it needs to be replaced.

Of course, you can notice the signs and symptoms of poor coolant/antifreeze quality before you even think to check the condition. Common warning signs that could indicate poor coolant/antifreeze are:

A low coolant/antifreeze warning light on the dashboard

Cool air coming out of the vents on a hot setting

The engine temperature gauge slowly rises into the red zone

A Service Engine or Check Engine warning light

Be aware of any of these signs and symptoms and you should book your car into the shop sooner rather than later to avoid a major repair or breakdown.

What are the benefits of flushing my car’s cooling system?

Peace of mind aside, here are some of the benefits of flushing your car’s radiator and cooling system:

Removes Harmful Deposits and Debris: Sludge and particulates are common in the radiator and hoses and can lead to more serious engine problems. A conditioner flushes these out for optimal performance.

Improved engine temperature and corrosion protection: After a flush, upgrade to a higher quality coolant/antifreeze and you’ll better protect your engine from temperature extremes and corrosion – improving performance and extending its life.

After a flush, upgrade to a higher quality coolant/antifreeze and you’ll better protect your engine from temperature extremes and corrosion – improving performance and extending its life. Knowing Exactly What’s in Your Engine When you buy a used vehicle, it’s difficult to know what type of coolant/antifreeze is in the system, its grade, and how many times it has been mixed with other fluids. If you’re swapping old for new after a flush, you’ll know exactly what’s responsible for protecting your engine.

How to flush your radiator and cooling system: 8 practical steps

Now that you know why and when to flush a cooling system, it’s time to show you how in eight easy steps.

Step 1: Make sure the engine is cold

Never start work on a cooling system flush when the engine is still hot or even warm. Coolant/Antifreeze can be extremely hot and will retain its heat for hours after the engine was last run.

Step 2: Jack up front of cart for easy access (optional)

You will find it easier to get to the radiator drain point (under the car) if you jack up the two front wheels.

Step 3: Open the hood, locate the radiator and give it a thorough cleaning

Clean the radiator with warm, soapy water, removing any dirt (especially around the cap). This ensures that no dirt or debris can get into the radiator and cause problems in the cooling system.

Step 4: Check the condition of the radiator

While you’ve jacked up the car and opened the hood, you can do a thorough inspection of the radiator to check its condition. Look for signs of rust and corrosion that could affect cooling system performance. Also check the two hoses that run from the radiator to the engine (supply and return) for signs of damage or leaks.

Step 5: Place a pan, bucket, or bowl under the radiator drain valve

Make sure the container you choose is large enough to catch all of the liquid that drains from the radiator and cooling system. Place it just below the drain valve, which is usually fitted at the bottom left or right of the radiator. The valve should have a stud at the end, often covered by a plastic cap that can be easily removed with a screwdriver.

Step 6: Drain the radiator by opening the drain valve

Put on gloves and loosen the screw on the valve (you may need to use a socket and ratchet or wrench). The coolant/antifreeze begins to flow out. When the flow is reduced to a drop, tighten the drain valve until you start flushing and keep the old coolant/antifreeze safe (your local mechanic can recycle it for you).

Step 7: Flush the system

To flush with water and remove any residue from the old coolant/antifreeze, fill the radiator with clean water using a hose and replace the radiator cap. Then start the engine and let it run for 15 minutes. Wait for the engine to cool completely, then repeat the above steps to drain the water from the system.

Step 8: Add new coolant/antifreeze to the fill line

Now it is time to pour the new coolant/antifreeze into the reservoir. According to the manufacturer’s instructions, fill the reservoir with fresh coolant/antifreeze to the fill line. When it is filled, do not immediately put the cap back on. Instead, run the engine for 15 minutes with the cabin heater on at maximum. This will bleed any trapped air out of the cooler before you reseal the system with the pressure cap. Switch off the engine after 15 minutes, put the lid on, done. Remember to keep an eye on the level over the next week or so and top up to the fill line if necessary.

So what are blanking plugs and why do you need to remove them to bleed a radiator? Why do you have to bleed a radiator at all? The important things first; A blanking plug (or the very similar vent plug) is a small, sleek-looking plug – either round or hexagonal – that you’ll typically find on top of a radiator, on its side, meaning at a 90° angle to a wall. Blanking plugs are placed on heaters because the latter are devices whose interiors must be sealed at high formation pressures.

And don’t doubt that air pressure in a cooler is a big deal. In fact, if you feel like you have a lot of air trapped inside, it’s important to bleed your radiator for this reason, basically. Excessive accumulation of excess air (i.e. trapped air bubbles) in a device is likely to prevent the thing from heating up properly and staying warm – and could even damage the radiator if left unchecked. Since so many modern radiators are fitted with drain/vent plugs, it is to be noted that if you feel you need to vent a bleeding process, you must remove the drain/vent plug.

Preparation for removing blind/vent plugs

To remove a blanking/vent plug from a radiator you need a special wrench. A two-sided radiator wrench with 10mm square ends would work best. But if you have one lying around, an Allen key, hex key, universal wrench, or combination wrench/wrench will probably do the trick.

In fact, any of these could probably fit in the square recess of a dummy/vent key and therefore remove it from a radiator unit – the benefit of a square radiator key, however, is that it ends up featuring an intentionally small through-hole to allow the screw of a vent plug will not be damaged when you insert the key into the recess of the plug and turn it.

It’s also worth noting that many modern radiators have hexagonal blanking/vent plugs. To remove these from a device you may not need a radiator key (or any of the other alternative keys above); Instead, you’ll likely find that an adjustable wrench or open-end wrench (of the appropriate size) works best.

Remove and reinstall blind/vent plug

So to remove a blanking/vent plug to bleed a radiator (and then reinstall the plug or install a new plug when you’re done), follow these handy step-by-step instructions below:

The petcock is a small screw just below the radiator and is easy to spot as modern radiators do not have other holes underneath that would require screws. Typically, the underside of a car radiator is covered with a plastic panel that can be easily removed to reveal the radiator drain cock.

How do you turn a radiator tap?

It doesn’t matter if you’re looking at the petcock or looking down at it, it rotates counter-clockwise. You have to imagine looking directly at the petcock as it fits into the radiator and turning the petcock counter-clockwise relative to the stationary radiator.

What kind of valve is a petcock?

A petcock is a small shut-off valve used to control the flow of liquid or gas. In the past, petcocks were threaded valves controlled by a butterfly handle; Modern petcocks are typically ball valves.

What is an engine petcock?

A petcock, or sometimes referred to as a fuel cock or fuel valve, is a 2- or 3-way valve at the bottom of your fuel tank. It works by directing fuel from your tank to the carburetors or injectors. Fuel is drawn from the fuel system by either gravity or vacuum.

What is a fuel tap on a motorcycle?

Gasoline, which is essential to the proper operation of your motorcycle, is controlled by a “fuel control valve”, also known as a “petcock”. This valve is typically located at the bottom of the fuel tank and can have a number of different configurations. Fuel injected motorcycles rarely have a petcock.

What is the connector at the bottom of the radiator?

A car’s drain plug is usually located at the bottom of a radiator. The plug is used to drain used coolant. The radiator fluid should be replaced regularly after flushing the radiator to increase the performance of your car.

What is a radiator faucet?

The petcock is a small screw just below the radiator and is easy to spot as modern radiators do not have other holes underneath that would require screws. Typically, the underside of a car radiator is covered with a plastic panel that can be easily removed to reveal the radiator drain cock.

How to use a radiator drain plug?

Take out your owner’s manual and locate your radiator’s drain plug. Take your used coolant bucket and place it under the drain plug, unscrew the plug and completely drain your old coolant. Replace your radiator drain plug once the coolant is completely drained and remove your radiator cap.

What does a radiator plug look like?

Hello Pitina, the radiator plug is usually located at the base of the radiator and looks like a wing nut. When removed, the entire contents of your radiator will be drained. A radiator drain cock is usually located above the bottom of the radiator.

Replace cooler, what do you use to clog transmission cooler lines?

I bought a radiator on the internet and am waiting for it to arrive. The good news is that since I have to wait a few days I can take my time and do the exchange “properly”. Quick question for the experienced – what do you use to cap the transmission cooler lines (if you disconnect them from the cooler) so you don’t lose all your transmission oil?

Thanks very much!

HOW IT WORKS: THE RADIATOR CAP An essential part that’s smarter than it looks

Most cooling systems from the 1950s onward are pressurized. As they heat up, the coolant and the air above it in the radiator expands. The pressure builds up and suppresses the boiling of the coolant. Water can be brought to about 107°C at 4 psi above atmospheric pressure and 121°C at 15 psi above.

The cap regulates the maximum pressure, preventing damage to hoses and radiator. After the engine is switched off, the system cools down and the coolant contracts significantly. The cover therefore has a check valve that allows air from the atmosphere or coolant from an expansion tank if fitted.

The cooler [ 1 ] is closed by the cap seal [ 2 ]. A spring [ 3 ] rests against the cap, which holds down the pressure valve [ 4 ], which is fitted with a rubber seal. As pressure builds, the spring and valve are pushed up, allowing air (and coolant) to escape to the overflow.

As the engine cools, a vacuum forms at the top of the radiator. Atmospheric pressure forces open the lightly loaded check valve and spring [5], allowing air to be drawn back into the radiator through the overflow. When an expansion tank is fitted, only liquid is expelled and returned through the overflow. The cooler thus remains permanently filled with coolant.

WHAT’S WRONG?

FEATHER RUST

Springs corrode, weaken and eventually break. The system will no longer be fully pressurized (or not at all) and coolant will be lost, causing overheating problems down the road.

CAP COLLAPSES

The internal elements of the cap are made of brass. This can crack, leading to degradation and consequent leakage and overheating on fast runs. Defective rubber seals cause the same problems.
