I am looking for a 12volt coolant pump, I understand that these are used on the water pre heaters fitted in large diesel and turbo petrol VW group cars.

I have found them on ebay for stupid money, can anyone tell me what cars they are used on so I can find one in a scrap yard.

Thanks

Rich

Usually used on turbo and larger engined car to keep the water cirulating after the engine is turned off.

Fitted to

MK3 Golf vR6

MK3 SEAT Ibiza Cupra ®

Audi TT (225)

Audi S3 (210/225)

SEAT Leon Cupra R (210/225)

Volvo 440/460/480 Turbos and Renaults with the same engine have one.

For guidance on pricing, I found a new one from DT for £130 ex VAT.

Thanks everyone, it is for a little suzuki swift the better half has, I dont think the water pump works properly, and dont want to replace it because it doesnt leak and I dont expect a new one will be any better.

So the plan is to use it to pump water around the heater (which is always cold) and encourage some water movement around the engine as the radiator fan is nearly always on.

I am sure you can understand that I want to try and find one in a scrap yard because the car is not worth the price of a new pump!

Thanks all for your help, anybody have an old pump they dont want??

Laing 12V 18W DDC-01 pump is about £50, or the D5 Vario is about £55. All good PC water cooling stores sell these.

Rich, why not? There are known cases (not sure about on here; the last one I saw was a non-Briskie workmate's TDi) of the drive splines stripping off the impellor of an otherwise healthy water pump.

I have spent about £800 on the car recently, in hindsight I should have scrapped it.

I am just looking for the easiest way to fix a problem that a new original water pump might not fix.

Thankfully I can always rely on the Briskoda crew for a truly professional answer.

Thanks all.

All I'm saying is that a non-leaky water pump is no guarantee of one that's working properly.

As a new pump is only £24,I would be tempted to flush out the cooling system and fit a new pump.

I have flushed the system (twice), and checked the throughput of the heater matrix which is fine. I have tested the thermostat, which opens at the right temperature.

To help matters it is an automatic, which means that the water pump is £36 which is just over £55 with the dreaded vodka and tonic and postage.

I just thought that it would be a simple fix to put an alternative pump in altogether, assuming that I can get one for £15-20 from a scrap yard.

I am absolutely certain that an "alternative pump" will not be a direct swap in, unless there's a higher tuned version of the same engine you can source a pump for.

Was going to suggest Swiftowners forum.but see you have already been there,they do not seem to be as well informed as the guys on here though.The only thing I can suggest is that after reading the newer swift workshop manual(Swmbo has a new swift)that filling the cooling system is quite involved and there is a bleed screw to release trapped air when filling,older swifts might be the same?

Yes, thanks, I did try there, but after they didn't help I always knew that everyone on here are always much, much better than anywhere else.

Credit to you all.

The old swift is very, very simple under the bonnet, not much in there at all, bit like a moped with 4 wheels.
