Replacing my water pump tomorrow. Anything tips or random things I should know? Started smelling hot anti-freeze about a month ago, just noticed the pump weeping today. It's gotten pretty bad.

Truck's got AC, btw.

 

well what motor u got?

make sure both mating surfaces are clean so u dont have any leaks

also it makes it easyer to remove the cluutch fan and fan shroud b4 workin on the pump.

dont puncture ur radiator

but its pretty strait forward and easy but if u dont clean ur mating surfaces ull just cause problems for ur self

 

4.9L straight six. Thanks for the tip on cleaning the surfaces.

 

yea 4.9s are simple

anytime ive made the mistake got it all together n it leaked had to rip it all back apart n make sure everything was clean

 

Put your truck's details in a signature so you don't have to remember next time.

Break the fan clutch nut off the water pump pulley FIRST. If you can't break it (and it's a Roy L. Pita), there's no reason to do anything else. Hold the pulley & turn the nut the SAME direction the fan normally spins. There are special tools available, but I made my own:



Don't lay the fan clutch flat - keep it vertical at all times.

Don't buy premix (50/50) or long-life coolant. Buy normal concentrated antifreeze & distilled water.
