Over Heating Problem

[minibeasts]

Hi,

If I drive for a short peroid I can keep the temp down to just above 90 but after a while the temp goes up to 120 and flashes...

It helps with the heater on to dump alot of the heat..

The bottom pipe from the radior is stone cold and the others are warm/hot on start up..

The garage said water pump is fine but cant look at the car unitl a week time..

I thought it could be the thermostat or the rad is blocked?

The cupra R has done 100K now...

Can anyone help?

How would they know that the water pump's fine if they haven't really had a chance to look?

My vote is on water pump...



...or thermostat.

Book it in somewhere that can see it sooner.

Hi,
I agree with Phil, Gonna be either water pump or thermostat problem.... my money would be on the water pump......
It may still be pushing a bit of water down the pipe to resovoir, but not round the radiator where its needed.
Hope you get it sorted.

Symptons sound identical to my recent water pump failure.. COMMON issue with the Leons.

Get it checked by a decent garage, mate. Although replacing it will mean cam belt as well... you need the belt off, obviously, to remove the pump so it's usually worthwhile changing that while in the area.

Ideally, get a pump with a metal impeller fitted. 9 times out of 10, when the standard pump fails it's due to the plastic impeller snapping, losing fins or just erroding. Try find an Audi TT pump. (I hear they have metal impellers).
