How to take a water pump off!

[SHOstuff]

Well as the subject says..how do you take off the water pump on my '90 mtx?

Loosten the waterpump pully. Take out the battery and tray. Then remove the serpentine belts. Disconnect the DIS connections then remove just the intake elbow. Then you will want to remove the TQ. limiting mount on the passenger side. Then you will want to remove the fender wall lining. Remove the idler pullies. After that loosten the upper and middle timing covers. You will probably have to move the P.S reservoir. After everything is out of the way loosen the waterpump bolts. Remove, replace, and reinstall. Good luck. thumb

Do a search for the front end 60k procedure. You may as well replace some of the other components while you're in there. The parts will be listed in many of the posts.

I'm not sure how many corners you can cut if you only replace the water pump. A lot of coolant will leak out when you pull the pump even when you think the system is completely drained. Since you don't want coolant on your timing belt or cps, you really shouldn't cut corners.

Good luck,

Hey Tom, why did you take off your superchips, and what performance did you get out of them? cost? labor?

I just replaced my water pump last weekend. You shouldn't have to remove the PS just the belt (at least on a 95 MTX). I was doing the CPS so I removed everything including the A/C idler bracket. Did you get the whole pump assembly or just the rebuilt pump half. If your replacing the pump front half only, it's quicker and you don't need to remove any of the hoses. I plulled mine completly off so I could sand off all the gasket material and have good clean mating surfaces. It also might help if you break loose the 4 pulley bolts before you release the tension on the belt. It'll still try and spin on you but the belt and another wrench was all I needed to break them free. No way to really get all the coolant out unless you remove the lower hose.

DigDeez, I took it off when trying to see if it was causing a rapid rise in temperature during hot weather; it wasn't.

Performance wise it opened up the secondaries at around 3800 rpm on my guage. Without it they open up between 4000rpm and 4100 rpm. I miss that. It was a big plus.

I left it off due to some negative posts I've read. I don't even remember the exact reasons, but I can't afford to risk my car, especially one that makes me smile! I'm just being cautious. Some here say it is silly in so many words. Also, I don't want to bother with adding octane booster.

Anyway, I'm just a newbie learning about my car and cars in general.
