I just repalce a radiator in my isuzu Rodeo and it still overheats? Do I need to burp the system? Not sure of the procedure for burping the system. Suggestions would be greatly appreciated. Thanks

Need a faster answer?
I would always purge the system of air before deciding if the overheating is more serious. Raise the front of the truck as high as poss with a floor jack and fill the coolant tank as much as possible, run the engine until it gets near to hot around 240F and shut it off and run water over the radiator, this will purge the system of air.
