i saw the thread but just want to know what everyone thinks????

metal or plastic????

No question "plastic". The metal one is not machined to the same tolerance. If you have a look between the two you can notice the difference. When I had the complete timing belt done I supplied the dealer with a metal impeller water pump and when they completed the final check on the complete timing belt job they noticed that the water temperature was running to high when the car was idling. The water temperature dropped once the car took up drive. The result was the metal impeller. They replaced this with the plastic one and everything was fine except I was out of pocket for the metal water pump and the R & R to swap the pump out. Go plastic.

I'm glad to see someone else had the same experience as me......

I found the same although it cant be said of all pumps, maybe there is a good metal impeller pump out there..

Thats a BIG surprise Wak !

For a couple of years on here we have always read that the best thing to do was to replace the water pump (when we change the cam belt) for a meatl one as the plastic ones break up !

Could it be a co-incidence and that the 'econ' button controlling
the fans was switched on or off during their idling test with the metal impeller ?

Well APS can supply a good quality metal part. Their argument is that the plastic blades break off the OEM part and can cause more problems.

For what it's worth I had my metal pump fitted by APS earlier this year and the temperature gauge has sat rock solid at 90.

So for me, it's metal everytime.

No problems here with metal - even in last summer's heat when idling in traffic jams...

I had metal put in mine and have had no problems

I fitted a metal one.
Awesomegti fit the metal ones to any they change.
Cant remeber the make of it now but this has been mentioned before so do a search on the topic or phone Awesome and ask them.
Out of interest I measured every dimension for comparison between the two pumps and found NO differences!

Yep Awesome replaced mine with metal last year too, no probs!

thats a co-incidence cause i phoned awesome today to ask and they are sending me the metal one they use

thanks guys

Ive got a metal one and have not experienced any problems

I have to agree, I was looking to going metal after all the posts on here, Andy Whats your views on this

I dont know why John, the info has been on my page for a year or two at least since I had my water pump changed to metal and then replaced back to plastic.

I highlighted it however....

that was one brand, English made I believe. I hear there are a few others, HEPU is one brand that I believe is German, if I could get a loan of one I can compare it to an oem plastic and tell you if the dimensions are the same.

Those who have had them fitted are either running good pumps or their thermostats are already degraded hence they wont see an issue until a new thermostat is fitted.
