      I know that you are suppose to burp the cooling system of air by running the truck with the Rad. cap off after a radiator flush, but should this burp procedure also be done as a maintence step in between cooling flushes to release any air that builds up in the system or will the air in the cooling system just simply rise to the top of the radiator and coolant just has to be added to top it off to replace the air? Does alot of air build up in the cooling system in between flushes that would need to to burped out? Trying to learn more about the cooling system and how to keep in maintaned. Thanks for the help

      Once all the air is out, it really has no way to get back in unless you have leaks.

      The over flow tank will also burp out any small air pockets over time. Like the others have said, the system only needs to be burped when it's opened. If you have no leaks, or don't open the system to work on something, you don't need to burp it.

      thanks for the replys. So if you open the radiator and the coolant is low, that does not mean there is air throughout the system, all of the air will be at the top of the radiator because air will rise to the highest point and will be replaced when coolant is added, Correct? Does the same hold true if the recovery tank goes dry, you just simply have to add more coolant to it? Thanks again

      the recovery tank should not go dry if it does you have to burp the system again with the engine cold fill the radiator up all teh way and fill teh overflow tank halfway then burp it again the next day
