If the temperature is reading high and you notice no hot air is coming from the vents, there is probably an air pocket preventing any heat. If it reads higher, you can try to rev the engine around 2,000 RPM, which might help the system burp out any more air and lower to the correct degrees. You want it to be at about 210 degrees Fahrenheit. Monitor the temperature gauge as the engine is running. The heat setting can be on high, and set the settings so heat is blowing out of the vents. You want to monitor the coolant level and make sure the thermostat opens up. Once the air is out and the coolant is full, run the vehicle for about 10 minutes. After Filling, Run the Vehicle and Monitor Temperature and Air from the Vents.Once you start seeing air in the line, close up the valve and grab another container of coolant. Once complete, attach a hose to the adapter, dip it in a container with the right coolant for your vehicle, and open the valve. It’s normal to see the coolant hose crushed down. The adapter will have a gauge, and it should takes a couple minutes to evacuate all the air. With everything hooked up, open the valve and put on a vacuum. Then attach a hose that will hook up to compressed air, and then connect an air line to the adapter. You’ll need to tighten the adapter airtight. For a situation like this, you can use an air lift system tool that attaches to the coolant fill area and puts a vacuum on the system. It’s easy for air pockets to hide in corners with this kind of setup. Maybe the engine is at the rear and the radiator is in front. It may be difficult to remove air pockets from some vehicles. Park on a hill, jack up the car, or rest it on car ramps. One trick that may remove any extra air is by raising the coolant fill area as high as possible. Raise Coolant Fill Area as High as Possible.If there is too much fluid in the reservoir, you can use a transfer or fluid extractor pump to remove it. Let rest of coolant fall into reservoir from the funnel, and then plug funnel with any remaining coolant and remove it. Once the bubbles subside, let the system and engine cool. With the vehicle running, you’ll notice bubbles burp out of the coolant, which is the system evacuating air. This raises the coolant level to improve burping. You can fill the system up with coolant and run the engine with the funnel attached without worrying about coolant spilling out the sides. If there is a coolant reservoir or a radiator cap, you can use a funnel that attaches to where the coolant is added. Attach a Funnel and Let Air Burp Out of the Cooling System.Once you start seeing bubbles or coolant, tighten the screw and there shouldn’t be much air in the system. As coolant fills up, you’ll hear air hissing as it’s removed. As you’re filling up the coolant system, open the bleeder screw. In this example it’s on the thermostat housing. Some vehicles have a bleeder screw to remove air from the engine. Look for a Bleeder Screw and Open It If There.The vehicle in this example self-bleeds a little with a hose from the radiator to the reservoir. You could squeeze the upper radiator hose to remove some of the air pockets. Squeeze the Upper Radiator Hose to Remove Any Air Pockets.More on how to bleed a typical cooling system For some vehicles, to burp the cooling system all you need to do is add coolant, start and let it run for 10 min, make sure the thermostat opens, which will burp air out, shut the vehicle off, let it cool down, and then top off the levels. Some vehicles will have a separate tank or reservoir to store and add coolant.Īdd coolant to the reservoir or radiator with the correct 50/50 mix. You may find a radiator or coolant cap attached to the radiator to add more coolant.
