Default Water pump replacement - doable?

My leakeage problem may be a water pump - 2001 9-3 eco-boost.

I have read through some threads on replacing water pumps and some way it is very hard, others that is is doable by the weekend mechanic. I think this variation must be for different engine designs.

What is the concensus for the 2001 2.ot eco-boost. Is the water pump replacement a hard job? How long? What are the biggest issues?

Did it in a few hours at a leisurely pace on my Viggen.

http://www.saabcentral.com/forums/sh...d.php?t=206826 See this post, it's for a 9-5 so disregard the part about the engine mount. Also on a 9-3 you may want to loosen the 3 bolts on the a/c compressor and slide it forward to get better access to the water feed line for the turbo

The turbo water line was the biggest problem for me.

I agree that the turbo water line was the most difficult part of the job. There are two banjo bolts - one on the WP itself and one on or near the turbo - it's a little line that snakes down and the goes right below the car as looking from the front. I ended up loosening it at the turbo and that made it much easier to remove at the WP and then subsequently replace on the WP.

The trick with the water line to the turbo is using the right tool. Basically what you need from snap-on is a 12 point swivel head socket to get the correct angle so you can turn the bolt. Otherwise you will do lots of cursing trying to get that one bolt off. It's worth the wait to get the right tool.

Is there a way to know for sure the leak I have is the pump? Pressure test?

Symptoms again: Looses fluid sometimes. No steam. Often no trace on ground but when there is it is in the right location for the WP. Fliud often disappears after being parked.

Make sure to check the condition of all your coolant hoses. For that leak location the lower radiator hose, and the small hose that goes from the throttle body to the back of the head, on the waterpump side. This one was leaking on my car and I was originally convinced it was the waterpump..

What does your oil look like?

Thanks

Oil is fine - no signs of fluid. This has been going on since I got the car (about 4000 miles) and I just changed the oil. All good there.

Also no sign of oil in the fluid... however, I am adding a gallon or so over the course of about 2 weeks, small quantities at a time of course.

The fluid loss is erradic. I will sometimes go 3-4 days with no loss and sometimes I will fill the overflow tank once or twice a day. Only 3 times have I had a spot under the car but when I did it was dripping from the undercar plastic shield in the right front corner. I dropped the shields but could not detect a precise location for the leak (it also started to sleet on me which dampened my enthusiaum to probe deeper at the time).

Any other ideas... I am still trying to nail the cause before I fix something that ain't broke...
