Anybody fitted an aftermarket water pump to their 4M41 engine? I had one fitted and have had overheating problems. This was part of a re-build project and have had overheating when engine under heavy load. Have replaced the viscous fan, thermostat and radiator cap with genuine parts.
So now it seems to be either the radiator or the water pump that is the problem. Has anybody had similar overhating problems after they fitted a non-genuine mitsubishi water pump?
