Think my water pump just let go....

[X911]

A grand for an OPC is probably not bad. Quotes I had from two local Indy's was £900 once you'd factored in the VAT.

I already knew the price of the part and what the job entails so I thought those prices were a little steep.

A week seems a long time to replace a water pump!

DIY is the only way to go.

For the record it is a very straigh forward way to go and there are a few you tube video's on how to do it.

But a grand!!!

I think i will become a Porsche specialist

Best making sure which ever one you buy has a plastic impeller. The metal ones can eat engine parts if it starts to fail and wobble.

Just to add...stick with the OEM Pierburg, Meyle, or Laso water pumps (composite impellers) that are made in Germany or Italy. Everything else comes with too much risk. Even if it has a composite impeller the last thing you want is pieces of it breaking off and going into you cooling passages/blocking flow...this is how you crack cylinder heads!

Agree completely. Pierburg is what I have ordered hoping for it to arrive this week but AUTODOC a bit slow.

The FCP Euro how to on YouTube is probably the best one. Just never know how it's going to go on your own car with seized bolts etc until you start but fingers crossed it goes smoothly!

AUTODOC is usually a bit slow, but the good price makes up for it..

Fingers crossed it goes well, it should be a satisfying job to get done :thumbs:

Only just got around to this job and have just got the pump and thermostat off. Bad news the impeller has imploded into a million pieces. Just wondering what my best approach is at this point? I pulled out anything I could get my hands on but chances are there will be small pieces that have made their way deeper into the engine. Anything I can do at this stage to minimise any damage or is just a case of won't know until you try?

My WP let go on Route Napoleon last October. If your impeller is made from plastic you should be OK as it's designed to melt in the system. Ensure you flush the system completely before replacing the WP and best to replace the thermostat at the same time.

That gives me some comfort thanks!

What is the best way to flush the system on the 996 (bearing in mind I am working on the driveway with the car driven up on ramps)?

I got the garage to do it. But... https://www.youtube.com/watch?v=U6XsRRraoo4

Good luck!

Thanks for this.

I am pondering over whether I should run any water through the system before I reinstall the pump just to try and flush any larger chunks out?

My plan after that is to reinstall everything then fill the system with deionised water and maybe some coolant flush. Run it then drop all of that back out again and then top back up with coolant.

I have recently changed a WP and flushed the engine.

If you are concerned about debris the perhaps the best thing to do is get under the car and remove the hoses which are the flow and return to the radiators.

Once that is done you can get a garden hose and flush out the stsyem to the radiators and turning the garden hose flush in the direction if the engine.

In other words, undo as may hoses as is possible and flush away. Obviously you will have also removed the WP leaving plenty od ways the flushed water can exit the cooling system.

I also advise that you buy from ebay a vaccum bleed, I bought this one https://www.ebay.co.uk/itm/35426852...UevdsewaH4K4l2XzbUMMrPkA==|tkp:Bk9SR5rerJ7sYQ

Without it it will be a nightmare to bleed the cooling system, you only have to watch that video previously posted to see the chap is struggling

AA man thinks it's the pump as well.

Can I ask if anybody knows the correct part number and manufacturer? I believe it is Pierburg but please correct me if I am wrong!

Be careful my AA man said the same it wasn't the water pump it was a y section piece of plastic that perished dramatically dumping lots of coolant and giving a spike in temp the fix was cheap and probably a good thing to do for anyone with a 996

Unfortunately for me there is absolutely no doubt that it's my water pump!

Thank you! I've spent the last couple of day watching every You Tube video there is on refilling the coolant system in a 996 and agree, looks hard work without the bleeder. Only problem is I will also need to invest in an air compressor which I don't really know how much other use I'll get from.

Could have issues accessing the rad hoses as car is currently on drive on ramps with the back end in the air meaning almost zero room at the front end. Also only have the one trolley jack which is currently holding up the block whilst I have the brace disconnected!

Obvious answers to both of these issues but both involve buying things I'll likely never need again! Although I do own a 996 so maybe that's a foolish thing to say...

This might be the answer to your lack of compressor.

Or tye SGS engineering, also on ebay, as their compressors are well priced.

I just bought a 5 in 1 52cc garden strimmer, pole saw/hedge cutter/brush cutter set and it is exceptionally well made, so i presume the compressors will be of a similar standard.
