ENGINE OVER HEATING REPLACED THERMOSTAT,CANT FIND WATER PUMP MITSUBISHI MONTERO 2001

Your water pump is driven by the timing belt; to access you will need to remove the forward portion of the engine (pumps/alternator/belts and such) when replacing the water pump you wll need to remove and then replace the timing belt and tensioner. Much care is needed to to insure the proper timing or things can go very bad. On a scale of 1-10 (1 being the easiest) I'd give this a 6.5 to 7.

I hope this may have assisted you,
