Mine's making some rather funny noises, so it's time to get it changed!

Looked on Design911 and there's a huge range of choice (based on wallet-size)....

https://www.design911.co.uk/fu/pt878_882_-cma81-cmo110-ct346/Porsche/996--911--1997-05/996-C4-3-4L-1997-08-01/Water---Coolant-Pumps/

Any recommendations - I'd prefer not to be bent over for the Porsche one though Very Happy

Cheers

Dan Smile

I replaced mine out of fear of failure as I hadn't done it during my five years of ownership and I'd been warned it's a service item. I got a Pierburg metal impeller one from Euro Car Parts. I can't remember the price, but it wasn't crazy high.

Pierburg water pump (with composite impeller) is what Porsche supply, available from other sources for approx. 50% of OPC prices. Comes with a gasket but it will be damaged in transit so buy a separate gasket from OPC or elsewhere for £10.

Might as well do your thermostat at the same time for £40-ish, standard or low temperature.

You'll need a pair of stainless hoseclamps, a 20-32mm for the pump and a 40-60mm for the stat.

While you've got it apart you might want to do the deflection/tensioner pulleys and belt too, these will cost you more than the pump and stat combined!

I've just done this job on my 996. Autodoc were cheapest for the Pierburg pump by a fair amount - https://www.autodoc.co.uk/pierburg/965622

In the end I got the pump, low temp thermostat and gaskets for around £210 delivered.

Autodoc get a fair bit of stick online but, other than a fairly lengthy delivery time, were good for me.

Thanks for the heads up Smile

The belt and tensioners were only done at the last service anyway. Thermostat was done when Hartech did the engine surgery too.

So it really is just the pump and gasket - everything else has been done.

I'll look out for the Pierburg one then Smile

Cheers!

Dan
