Having problems with your 1999 Chevrolet Malibu ?
I have a leak coming from the upper radiator hose (someone else looked at my engine and told me this) the only problem is i have NO idea which the upper radiator hose is...some kind of diagram would be great! also how do you test to make sure thats what it is?
The upper radiator hose sit on the very top of the radiator pointing toward the engine, close to where you add coolant or water to the radiator, where the cap is at, before removing cap look for any wetness, if you don't see any, top off radiator install cap back on, start engine let it pressurize and look for leaking, DONOT remove radiator cap with HOT engine.
You should be able to see the leak being that the radiator hose is right there around the top where you would fill or check your radiator fluid. you can also google it if you absolutely need a picture like engine specs of your year make and model.
