Good morning,

can someone supply me with the part number for the thermostat link pipe seal/s, for a 2.5 V6. Can't see them listed in the "how to"


Many thanks

And just for curiosity ,what is considered to be the average time to do the job DIY then ? as my temp takes a fair while to reach 95 c now so think might be new thermostat time for me sooner than later too.

It took me about 4 hours including half hour for a brew & a butty.

I believe that 90 is fine.Mine doesnt very often reach 90 so needs a new stat.

What's the problem with the engine running cooler? I would have thought engine cooling would be good?  :)

The 'stat should regulate around 92deg

Engine stat running too cool is bad, if it thinks its cold its going to chuck in more fuel, not good for your wallet. Or the cats  ;)

You want your engine up to  operating temperature as soon as possible, otherwise it's on 'choke' for longer than necessary and using more fuel than it should.  ;)

I would've thought any cold-start enrichment would be over and done with by the time the ECU saw about 70C coolant temperature?
Anyone know different?

I guess it'll take longer than it should to get even that far, if the stat is playing silly buggers though.

Sure will.  :y :y
A new stat in both my Astra & her Smart made a huge difference in the speed at which they got to temp

My M/F tends to creap up to 90 after about 10 mins or so and after driving for 20/30 mins settles down at mid point whaich is 95 only going up to 97.5 if in slow traffic or pulling up long hills at speed.

I am sure it used to reach mid point temp ( 95 ) lot quicker than of late  despite coolant being recently flushed through and new water pump fitted.

Would be nice to save a bit of fuel as agree all is not running properly until temp reached so may invest in new stat and housing.

Thermal efficiency.
