Hi

 

First post be gentle. My Octavia 2012 1.4 TSI has just had its second water pump replaced.  The first failed at about 7k miles and 15 months from brand new. Second pump has now just failed at 8.5k miles only three months later. Any ideas? Is this a common problem? Could there be a cause?

 

Thanks

Something not right there,it could just be a dodgy batch of water pumps,did the two leak coolant or the bearings fail & become noisey?  If it was poor workmanship id of expected them to fail well before 8.5k was covered. Welcome to the forum by the way!. 

First one became noisy then just started to leak as it was replaced (obviously it was fitted when the car was built), second one was just noisy (was fitted by skoda dealer under warranty). Could there be something wrong with the tension in the belt? causing early failure?

I dont know how the belt is tensioned on the 1.4,id of thought it should be auto tensioning,however a over tightened belt can cause the bearings to wear early in the water pump. 

It will be interesting to see how this one fairs, I just hope its a faulty couple. Car has been excellent otherwise, nice and smooth easy to drive.

I replaced the coolant pump on my 1.4 TSI after 3 years and 7 months (27500 miles). It had been leaking slightly for the previous two or three months but was not unduly noisy. The requirement for an early replacement has been my only disappointment with the car thus far.

 

The drive belt is tensioned by an automatic tensioner.

 

Many thanks,

Interesting that still seems quite early in the water pumps life to get replaced, especially on such low miles.

The water pump squeak has started again, looks like its back to the dealer again..... I wonder if something could be causing the pump failures? belt too tight?

Interesting post this as a work colleague has a yeti 1.4tsi and is now on his THIRD water pump at just under 50,000 miles! One lasted just 12 months before it was making a noise again which led him to take it to the dealer for diagnosis. It got replaced just after Christmas. His driving style is very relaxed and it does a fair bit of motorway running as he travels from north London to Norfolk at least twice a week. I wonder what could cause these premature failures?!

My mileage is 12000 miles, it will be getting its 4th water pump from new.
