Water Pump Replacement
I have a 99 c5 and I recently had to take my car to the dealership for a steering column lock issue. The dealership said they assessed everything else on the car and said that I was going to need to replace my water pump soon. Then the service guy stated it would be $800 to complete the job. I was like whoa, hold off on that so i can see if it can be done myself. Can anyone offer information on what all that the dealership would be doing that would make the job $800? Am I being taken to the cleaners or does it sound legit to any of you?
Your input would be greatly appreciated.
Thanks
So I decided to do it myself, about $220 for the pump and $10 for the gaskets.
Change the thermostat while you are at it, make sure the thermostat is compatable with the new pump before leaving the parts house. Another $30 or so.
I used rubber bands to hold the gaskets and bolts in place until bolts were started (two bolts out of three each side), then cut and removed the rubber bands. String tied around two of the bolts on each side might work better.
About 2- 2 1/2 hours.
You think the coolant is fairly well drained by draining the radiator, but when the pump comes off, more comes out. Be prepared for a mop up.

edit- they also did a coolant flush and pressure test

If the brains at GM would have used a stud instead of bolts, this would be a 30 minute job, add 10 -15 minutes for the proper thermostat.
The gasket issue is absolutely moronic but the rubber band idea or using a little dab of permatex and letting it dry will help out.
I paid $98 from advanced auto for the pump, $15 for the thermostat with housing, 2 gallons of dexcool at 12.99 each, and 2 gallons of distilled agua @ .79 each from wal-the-mart (already had an old tube of permatex)..knocked it out in less than 2 hours (that included lunch break)

Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
