Waterpump 2015.jpeg

 

Well it looks like a clean break !

Jesus Christ!

So how many miles do you think the pump has done?

165k !  

 

I would have been mightily p****ed off if I'd been the last owner:-

 

They spent a fortune on a full Skoda history including two cambelt changes (before my third one) and I've scoured all the receipts and there is nothing about a water pump needing replacing or even a recommendation to replace. At one point there is a standard text "we recommend replacing the turbocharger every 120,000 miles" !

 

As it seems to have been 'no expense spared', that must have been down to the fact that there is no recommended replacement interval and/or the dealer just not saying "while we're doing you cambelt, how about the water pump?"

 

Car running great - hydraulic damper, tensioner, belt, water pump and thermostat while they were at it !

There is no specification on the service manual about replacing the water pump at specific interval.

Will be replaced when it will fail,like the steering pump or fuel pump.VAG sees the waterpump like any other pump on the car,replace when will brake

Agreed - but neither of the other two *could* destroy the engine ?

that;s correct

Seems like its had a good innings then.  Wise move on the other parts too

I put one with mettalic impeller.Hepu

Sort of OT, but when I sold cars many years ago, we sold GMs Northstar engines. Nice V8s Their party trick was they could run without water for about 100 miles. If memory serves me right, the main reason was they could alternate which cylinders where being used to share the heat load throughout the engine. Clever stuff back in the early 'noughties'

never heard about this

We tried to use it as a selling point, but on a brand new car, most potential owners weren't impressed, ie why would it need to do this. It also had an incredibly long service cycle for the engine.

 

Just had a quick read about this engine and it did it's trick by switching off alternative banks of cylinders. Clever. Can't remember if I ever managed to sell one though

165K!? The water pump on my 2002 Octavia 1.8T 4X4 Estate needed changing at just 18738 miles and 4¼ years when it was discovered that plastic impeller was starting to disintegrate. Fortunately I had opted to have the water pump replaced at the same time as the first cambelt change else I would have been in the same situation as the OP in fairly short order.

That was lucky / good planning. My first first 51 plate 4x4 was sold with 78k on the original pump.

 

I had a chat with someone at Skoda HQ the other day about the whole plastic v metal impellors thing (and why they don't just give a recommended replacement schedule!).

Basically VWG still stick with plastic as when they break there's a fair chance you save the engine (like mine). With metal, you don't.

i am not sure if my Fabia currently has a plastic of metal impeller water pump but the next one will be plastic for the very reason above.

Why the metalic impeller would break the engine?  

The theory seems to be heavier load on the bearings causing failure ? If a metal pump breaks up it might do more damage than bits of plastic in a hot, moving engine...

I read the debate on forums about mettalic impellers,and is full of rubbish...tonns of rubbish

There clearly is no 'right and wrong' but Volkswagen Group now sell over 10 million cars a year and sell 'x' million replacement OEM pumps each year... which contain plastic parts.

 

Either its a very good thing, a great way of increasing profits, or both...

Cars used to have metal impellers , they didn't fail the bearings did

A pump wich won't fail won;t bring a demand for spare,so no profit.

I had an 1990 Audi V8 and the OE parts were very ,I mean very cheap,and I was talking to a friend who worked at the dealership and said there are tonnes of spare parts for this car because they never break,and they are disperate to get rid of them.I paid 60 pounds for a OE dash heater 10 years ago when I had that car
