I loose 1 or 2 quarts of coolant every 2-3 months. Oil tests negative for glycol. Top hose is not pressurized on startup. Recently replaced potmetal coolant fitting that goes into the thermastat housing. Never had a problem before I used Water Wetter. Any ideas? If I replaced the coolant and got rid of the Water Wetter would it help? I use the truck to tow a large trailer and don't want to have a problem on the road.
