Whats causing my 1999 Dodge Stratuss radiator fluid to slowly disappear?
There must be a leak either externally or internally. Watch for puddles, could be water pump bearings going bad. Shampoo your engine bay and allow it to dry for an hour or so. Any leaks should appear now. You could have an internal leak at the seal of the intake gasket to the head. You should have it pressure tested for sure. There could be a minuscule leak in the head gasket, which can be sealed with a Bar’s Leak product made for this purpose. If and when you find and cure your leak, DON’T USE THE GREEN ANTI-FREEZE!! It will exacerbate the problem and cause more trouble besides. Eventually flush your system and use Mercedes Benz coolant. It protects better and lasts longer, and so will your expensive radiator, water pump, and plastic colling parts. Trust me!!!
