My wife's '04 Avalanche has a slight drip from about the center of the engine. Not much, drips a spot on the driveway when she backs it out of the garage, leaks all the way down the driveway, each drip is about 6' to 7' apart. Tried looking underneath to see if I could see anything such as drips or indication of a drip spot so I could trace to the problem, but nothing obvious.
Was going to check the cooling system (heater hoses, radiator, water pump from what I could see of it), but nothing obvious there either. I have an older style pressure tester (one that you attach to the radiator fill where the cap is) but there is no radiator cap?
I also thought about flushing the cooling system, but hesitant to just plunge in! Guess it is like the classic style, put a T in the heater hose?
What am I missing about the radiator cap?
