which impeller type on water pump

[Jules59]

2005 Fabia VRS; had a new ASZ engine installed in 2007 after original was hydrau-locked.

Does this engine have a metal or plastic impeller on the water pump?

When I change the cambelt later this year, should I use a plastic or metal impeller water pump ?

Ive read conflicting reasons for using a plastic or metal impeller.(the metal is said to cause more damage if it fails hence the use of plastic but lasts longer than the plastic).

Your opinions sought .

Thanks.

Plastic and you should replace it with plastic

+1 on plastic....I fit OEM waterpumps to mine...far rather have the time to fix it with just the posibility of a slight overheat which can be controlled....than the terminal failure of the metal impeller sticking causing the timing belt to shread....and the lovely sound of valves to pistons kissing!!!

ok . the decision is now obvious - many thanks.
