2000 Pontiac Grand am gt
3.4
Check engine
work done to repair = replaced thermostat
GM tech = jk
question = the steps to change the water pump on grand am gt 2000
JK:
To remove the water pump, first, make sure engine is cool and no pressure in the
system, remove the belt. Then hold the pump pulley tightly and remove the 4 10mm
bolts that hold on the pulley. Tap the pulley to remove. Then remove the 5 5/16 (or
8mm) bolts that hold the pump. Be sure a drain pan is under the car to catch the
coolant. Clean the mounting surface of old gaskets. Install new pump, pulley, belt,
and bleed the system.
Let me know if you need more help, JK
VISITOR:
thank you much. So i dont necessarily need to jack up the engine 6 to 8 inches to
get it out and what about draining the cooling system completely before removal of
pump? Thanks again i am trying to tackle this job on my own with little experience,
but so far so good
JK:
No. On the 3.4, you can pull the pump up and out without lifting engine. It is a little
tight, but does come out.
For me, removing the pump and having the coolant dump into a drain pan is quicker
and easier, although can get messy if you miss the pan. Removing drain plug on
radiator is just kind of a pain to do, and can break off. You will loose nearly as much
coolant as pulling the radiator drain plug.
