Water pump AISIN or OEM Audi

You can save yourself some time and money by buying the Aisin water pump / timing belt kit on RockAuto. Don’t mess around with other ones. The parts are all the same OEM you’d get from Subaru at a fraction of the cost, except for the pump itself — but that’s a good thing because while Aisin didn’t make the pump for these, they were an OE pump maker for Subaru and the company that made the OE one for that generation (Gates) has apparently started producing crap. I don’t think Subaru even uses them anymore for their OEM pump.

going strong doing water pump and new oil pan right now. Tensioners were done as a precaution at 195k.

Water pump started leaking so replaced it, the thermostat, and the pcv. Oil changes 4k-5k. Love the car.

You should use Aisin or OEM water pumps.

When I do side jobs I use an aisin branded water pump and timing belt tensioner. The aisin kit is top notch.

This time the shop foreman went through the car soup to nuts again, replaced a fuel rail connector, and the water pump.

I owned a 2009 4.2L V8 S5, had to get a new water pump & housing. euro specialty shop did it for me for ~$700.

Just be aware that B9’s are subject to water pump failures which can lead to the engine overheating. For months (Since March) I’ve noticed a “Whistling noise” coming from the engine bay while driving. Took it in to get it looked at (non Audi dealer) and was told it was normal. Drove it and drove until one day the car told me I had no coolant… that’s odd. Go buy coolant and keep driving. Now the car overheats and spits out all the coolant. Now it’s making sense. Either a combination of bad TStat sensor & water pump or just bad water pump. The fact that it never told me the coolant was hot the first time is spit out all the coolant leads me to believe both components are bad.

Had mine replaced last month before it broke again. The component that failed was the gasket for me then the pump failed and wanted money.

Had the dealer do the water pump on my 09 A6 3.0t and it was like $1800 for that alone.
