I have a Rav4 2004... it just started a coolant leak. I'm sure if I just tear into it I will get it fixed. I would however like to have the replacement parts on hand when I tear into it. There is a "aluminum" cast attached to the engine side of the bottom radiator hose. The leak is coming from between the cast and the engine block. Does anyone have a book that might tell me what goes in there. Paper gasket... O Ring" or whatever. I just got the SUV a couple months ago for my wife. This seems to be the only issue and it just started. Any idea of where I might get a free repair book for it?
