Temp. guage seems to take forever to reach the 2nd line.Themostat?Would this effect M.P.G.
-
Probably thermostat mate and yep low engine temperature = lower mpg
-
Apart from thermostat and gasket ring anything else needed?

Depends on engine

It,s a 2.2
-
Petrol, diesel?
-
Might be worth running some coolant flush threw it first ;)
-
,52 2.2 petrol
-
def thermostat, good luck it's a beatch!
-
Any pics or a How To.Above doesn,t sound too good :-\
-
There's def a guide for V6, not sure about 2.2 :-\
Someone's bound to have done it though :y
-
Thermostat renewal/replacement on a 2.2 is a doddle :y

2.2 Thermostat Assembly....Part No. : 90501081 This is the VX Part Number for the complete assembly. 92deg C. thermostat can be purchased seperately and fitted in the existing housing if money is an issue but tbh, you are better off buying the whole gubbins :y
The Torque values for the thermostat housing to engine block are: 15Nm/11lbf ft. Hth :y

Just slight understatement, its 15 minute job unlike the crappy V6's which take half a friggin day to do! ;D

Best antifeeze to use?
Any idea of mix when refilling?
-
GM own is well priced on TC, always 50/50 mix with water :y
-
What about the stat itself? Buypartsby sufficient?
It seems to take a long time for the gauge to move on my (poxy) V6, so may need to go down this route myself.

I can only speak from my own experience on this question. I followed MarksDTM's advice that my problem was a faulty 'stat and he was correct :y, but I then compounded my problems by buying a cheap 'stat from a Factors and fitting it into the original housing only to have that part repeatedly stick open ....so back to square one! :-[ So in imo, only buy a genuine GM OE stat for your V6 as they are a bloody site more involved to change than a 4 pot & you only want to be doing that job once! ;D :y
-
Anyone got a Vx price for stat and housing?
Also BPB do a kit which includes the housing. Anyone any experience of these?
All hypothetical at this stage, but worth asking :y
-
Approx £45 ish,when i priced it up,but i went for thermostat only from unipart which was £9

Followed this advice from Elite Pete last November.
"I've fitted quite a few of these in the past and never had a problem :y"

Got one fitted it and so far all is good. It was the thinner housing so used a washer and couple of M8 nuts as spacers. :)
-
careful on the bolts as you remove as my friend sheared his so we had a blow torch on it with some mole grips for about 2hours trying to get the bolt out.
Looks the same as the 1.8zafira I did, 10min job
