2003 Mitsubishi Diamante ProblemsThe automatic transmission may fail prematurely
The automatic transmission may fail prematurely requiring overhaul or replacement of the transmission.
A brake pedal pulsation may be noted on brake apply. This is commonly caused by warping of the front brake rotors. Our technicians remind us that re-machining (turning) the rotors can correct this issue but the repair may last only a short time as the thinner rotors would be even more prone to warping. Replacement of faulty rotors with high quality parts is often the best option in these situations.
A coolant leak may develop from the heater core, requiring replacement of the heater core.
2003 Mitsubishi Diamante QuestionsI am trying to do a repair in the water cooling system. I need to remove the water cooling pipe and don't want to remove the engine parts. Is there an easier way to remove and replace the pipe? If so how should I do it? (1 answer)
the pipe is one of the water cooling pipes that sits in between the v of the engine...the book I have does not seem to give a clear direction on how to do this and don't want to pull everything apart.
