Question? 2018 GMC Sierra 5.3 water pump failure at 29k. Picked up truck an drove home 20 minutes smelled coolant figured it was just residual burning off. Got home to drop other car off and wife walked up to truck and we saw steam from hood. Opened hood and upper hose not connected off shut off truck. Overflow empty , no coolant on the ground or driveway, but everywhere under hood, no check engine light, slight increase passed middle temp. Dealer reconnected filled and said all good. Told me I caught it just in time, and that the computer had no codes from overheating, and that if it would have overheated the check engine light would have come one, and the truck will shut itself down to prevent overheating from damaging the engine. Is this true? I picked it up tonight and drove from Downtown SLC, Utah up to Park City, Utah a nice mountain climb and it drove perfect and no overheat issues. But it has been 30 degrees here as well. I figure the drive up when it is 100 degrees in the summer will tell the tale. Thanks for your feed back ! I just find it hard to believe that no damage occurred.
