I need to replace the water pump.

Replacing Water pump and coolant question

Suggestion

simply draining enough to change the water pump but I think the conventional wisdom would be to completely flush the coolant system while you are working on the pump.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I got the water pump pulley failure. I've heard this failure is pretty rare case. Check the following URL to see the failure. https://www.dropbox.com/s/4p1464ttwc..._1486.mov?dl=0 I need to replace the water pump. Does anyone know how much coolant will be draining by this job? I'd like to drain the coolant as much as possible to refill it. Thanks.

POST 2Original post

I would suggest always start with a search of the forum. These basic things have been discussed many times. Best procedure to drain (in my opinion) is the post on "Simple 3 step coolant flush" or something close to that name which is actually on the "new posts" link about halfway down the page. This is a flush procedure vs. simply draining enough to change the water pump but I think the conventional wisdom would be to completely flush the coolant system while you are working on the pump.

POST 4Original post

5-10 on the DIY scale. Lots of threads as posted on the messy job. I didnt drain the front radiators. At 30k miles and lifetime fluid from P and just replaced the amount that came out with the super duper P factory fill and called it a day. Did mine as part of my obsessive preventive maintenance mania.

POST 5Original post

The whole system contains 5 gallons. Start reading... https://www.pelicanparts.com/techart...eplacement.htm And... https://rennlist.com/forums/996-foru...+coolant+flush

POST 6Original post

I just did a 996, it took 3 gallons on the way back. There must be more in the front radiators.

POST 7Original post

You will loose about half the coolant the the pump pops off the block. If the belt looks good and the thermostat was working fine, leave them alone.

Based on the video he posted.....that belt is toast

You are right. Just looked at the video too. He should spin the rollers to see if the bearings are good too. Looking a the roller surfaces, this car sat for a while.

POST 10Original post

Post a picture of the impeller when you pull the water pump.
