How to properly bleed your car’s cooling system
After replacing the water pump or thermostack, it can be really difficult to get the entire air out of the cooling system. The engine can easily overheat and can actually cause serious damage to the engine.
There are several steps that make the entire situation much easier. Follow this step to get the air quickly and safely for step instructions.
Various ways to bleeding in car cooling system
In fact, there are two different ways to remove air from the cooling system. Old manual method
The manual method is an older variant of the bleed system in the cooling system. Some cars have one or more air vessels to remove air from the system, and some cars don’t have this air valve, making it much more difficult. This method does not require any special tools and you will receive a step-to-step guide, as you will do in the article later.
Vacuum method
The new way I use myself is the vacuum method. To use this method, you will need a vacuum tool and compressed air (depending on the tool). However, this method creates a vacuum, sucking out the entire air from the cooling system within seconds, filling the entire vacuum space with coolant. This is a really efficient method if you have tools and don’t have to worry about bleeding in your car. Perfect results each time, and the process takes less than a minute.
If you’re interested in any of these tools, there are tools available on Amazon. Please note that this tool requires an air compressor. This is an affiliate connection. This means you can use it for free for qualifying purchases.
If you need to buy one of these tools and don’t feel like you’re not going to the workshop, this is fine too. This way, do it if you can’t access the vacuum ventilator.
How to bleed your car’s cooling system
Step 1: Prepare the coolant
The first step in this guide is to make sure your anti-frost freeze is ready. You should always use the appropriate coolant required by the manufacturer. The wrong type of coolant can damage the engine!
If you are unsure which coolant to use, check the repair manual or contact an authorized dealer. Mix the coolant with 50% water and 50% coolant (for concentrated anti-frost coolant).
Always read the coolant instructions for correct instructions. If you live in a cold country, you need to make sure the coolant mixture is correct. When the coolant freezes into the engine, the engine will be destroyed.
Step 2: Jack in front of the car
Although not many people take, the step they achieved better results is to increase the front of the vehicle first. Using this method, you can extract air from the car, especially if the filler cap is on the cooler. If you have a car with an external expansion tank mounted on the back of the engine, this may not be necessary.
To increase the front of your car, you can use a floor socket or place the car with the front on a steep hill.
Always use Jackers to avoid accidents when lifting your car over the bushes on the floor.
Step 3: Fill the coolant to the maximum
Once the front of the car is up, it’s time to fill up as much coolant as possible. If your engine has air valves, open them at the same time while adding coolant. Close them as the coolant flows out of them.
Anti-freezing is toxic. You should always check to see if the coolant is not flowing properly on the floor or on the street. All coolants should be returned to a local environmental assessment. Remember that if animals drink coolant they can become very sick. Be careful! If you have the coolant as much as possible, proceed to the next step
Step 4: Start the engine
You need to start the engine now. The best way to do this is to get help from a friend. When you start the engine, the water pump can push the coolant out of the cooler when there is air in the system.
Step 5: Maximize climate control heat
After starting the engine, you need to convert the climate-controlled heat to maximum. It depends on the car, but many cars use valves that prevent the coolant from flowing into the car’s heat pack when climate control gets colder. This step doesn’t make a difference to these cars as other cars divide the air flow rather than the coolant flow. No matter which model you have, placing maximum heat air conditioning is an easy step.
Step 6: Rev the engine to 3000-4000 rpm
Put your friend into the car and let him rev up your engine to around 3000-4000 RPM. This could cause the coolant to flow out of the radiator if you do not use the spill tool. Keep the RPMs steady while you are working in the system. Make sure that the coolant is not getting too hot while you work on it, though.
Step 7: Open Bleed Valves Carefully
While your friend is revving the engine slightly, you can now loosen the air bleeding valves. Ensure the coolant temperature is not too high as it will be dangerous to work with your car then. Be attentive to any coolant temperature peaks and coolant leaks at this point. Open the bleed valves carefully until it comes to water from them and then close them. Do this a couple of times until it only comes coolant from them when you open them.
Step 8: Refill coolant if necessary
Close your air bleeding valves. Let your engine idle again and recheck and refill the coolant level and lower the front of your car. At this point, you should repeat these steps until you get heat inside the car and your coolant temperature reaches 90C and stays there. Put your radiator cap back. If your coolant temperature is now at 90C (work temperature) and you have heat inside your car, the air should now be gone from your vehicle. Warning: Hot coolant can harm you if it’s not used with care.
Step 9: Go for a test drive
You should now make sure that you can’t find any leaks after your repair. If it seems good, take your car out for a long test drive. Be very attentive about your coolant temperature during the test drive, and make sure the car does not start to overheat. Overheating can cause your head gasket to blow, and you really do not want that to happen. Check all the functions and the temperature of the climate control.
Step 10: Fill coolant again
If your test drive went well without any temperature peaks or other strange behaviors, open your hood and recheck your coolant level. Check for any coolant leaks.
After this, you can let your vehicle stand for a couple of hours, then take another test drive, do the same procedure and check for leaks and the coolant level.
After all these steps, your repair should now be successful. If there are any strange behaviors, repeat this guide or continue your troubleshooting.
