replace water pump on 1993 4runner
If it is anything like my 89 4X4, you will have to remove the radiator, fan, and all hoses. Water pump is usually on the back side of the fan. Also replace your thermostat while your in there.You may also have to take out your alternator and mounting bracket also. Or just go to local autozone and pick up a Chiltons repair manual.
