Replacing water pump E9 500


Recommended Posts

Hi guys

New to this forum from sunny central west NSW Australia

We have an aussie built 1986 Superliner series 2 that we use for farm work including pulling a grain roadtrain at harvest time.

It has an E9 500 engine that has an intermittent coolant leak around the water pump area.

Picked up a reman water pump from my dealer yesterday, given that it is an internal pump, how hard are they to fit?

Can I do it myself , or are there tricks to it that require a Mack mechanic?

Thanks in advance

Not too bad of a job. I did mine a few yrs ago. Take off lower rad hose, coolant filter and anything else that might interfere with removing your water pump housing.. I think there is 4 or 5 bolts fastening housing to timing cover. The pump core just fits in timing cover and is held in place with the pump housing. Not a bad job. At all I changed mine when it was still in my MH Cabover, didn't take me no time at all. In a Superliner it should be a snap.
