Do you have to have the special tool to remove the water pump

On a Northstar? Yes, it is necessary.

Use a prybar........

Actually, there is a 1/2" drive notched socket that fits inbetween the pump - tabs. Remove CLOCKWISE. When installing, be sure not to over-do - it. The tabs can bend under & slip past the stops. Grease the back side edges to avoid corrosion where it seats. You may need an air wrench to 'break' the pump loose ( due to the corrosion ).

Careful using a breaker bar when installing, so not to flaten the tabs.

You may be able to borrow the socket from your friendly mechanic.

I have one in my toolbox, along with the other 40,000 dollars worth of tools ;)
You can get them pretty cheap nowadays.
Some places will let you rent them or some parts stores even let you "borrow" them.

Don't overtighten it when you install it.
All you need to do is "crush" the o-ring for a good seal.

Last time I was in a local Pep Boys I think they were selling it for about $25 or so. Not too expensive as far as specialty tools go.

What type of prybar are you talking about? Will a long flathead screwdriver work? I am just trying to replace the pump so I can sell the vehicle, don't really want to purchase a tool I will never use again.

You can't do it without the socket.

It is almost crazy to try it using a prybar with the availability of this tool.

I was kidding about the prybar........ Look up at reply post #6. That shows the notched socket. Some autoparts stores rent tools, some friendly mechanics would loan the socket. There is no other way to remove/install the waterpump without damage. READ the replys again!

Yeah, I found out Autozone rents it out. It was a major pain to break free!

It was hard to break free because the backside of the water pump stuck with corrosion. Use a lithium grease ( or something longlasting) behind the pump before installation.
