Engine Cooling problem
2000 Chevy Silverado V8 Two Wheel Drive Automatic 226000 miles
I have been loosing engine coolant every2-3 months for over a year.I have had a pressure test done and no problems found. There are no signs of any leaks at all, no oil contamination from water, nocracks in hoses, no overheating problems, ac/& heat work fine. No thermostat problems. But after I am through driving and I park the truck and shut it down, I can smell the coolant on the front drivers side of the truck.I have checked my repair manual and there is a mention of a " Vacuum Atmospheric Valve", but it does not show where it is.I'm just guessing that since I can smell but not see a leak, the word" Atmospheric" would be a place to check.
