Picked up new stat, the rubber gasket is already on the stat housing.
Is it worth taking this off, then putting a tiny bit of grease around the rubber gasket, then re-seating?
Or just apply to the surface/stat housing on the engine block where it's mounting to?
-
If the seal is happily in place, simply fit it ;)

Ta :y
A little job for the weekend :)
-
10 mins max to change ,any longer than that then you shouldnt be working on an engine lol :y
-
You still got time to do it tonight..its dark and cold....ideal job.. ;D ;D
-
Done it before :y
Was one of my very first jobs that I did :)

I remember :y. Probably a good excuse to flush the coolant through as you have to partially drain anyway :)

That's why I bought a bottle of coolant too :y although it's not long since it has a good change. Belt and water pump was changed last year.

Hummm something is still not right, only warmed up to ~80c on the gauge today really. Huge chunk of the first part of my commute is stop/start 50mph average down the M3. Bit more speed on M25, saw it rose very slightly.
Oddly, when I came off motorway for Heathrow (and came to a stop) it went to 85 quite quickly. But going around the Heathrow perimeter road, it would range from 80/85, tending to go to 85 when stopped.
Stop/start driving saw it around 82 :-\
Parked up at the office, it went past 85 up to 90. Then stat must have opened more and brought it back down to 80, then onto 85 again. Fan did not turn on, so must have been via the stat.
I do have a slight leak from the coolant pipe on the stat that runs to the throttle body, but then temp changes don't appear right.
Normally once on 85c it would stay there, no matter what. :-\

What is the heater temperature like? On hot is it pumping out very hot or just warm?
I have a 2.6 that has hot air from the heater, but the actual temperature gauge barely gets to the first mark on the gauge. I am thinking that maybe the sender unit that isn't registering the correct temp to the gauge.
On an old VW Golf GTi MkIV that we had years ago, the sender unit also sent the temperature readings to the ecu regarding the air fuel mixture, so a dodgy sensor gave the wrong info resulting in incorrect fuelling. Don't know whether this aspect applies to an Omega....

Heat is good, perhaps not the cooking heat it's been before. But still very hot.
I'm thinking air pockets/trapped air, but then I might not get heat at-all :-\

Heater set to Hi, fan to one bar, then expansion cap off and run it until the fans kick in twice, cap back on and give it a run, then report back :y
Don't forget, start this from cold and once done, again from cold, check the stat to rad hose as it warms up :y
-
Getting fan to kick in a? That's quite hard on the 2.2, only tend to hear that on a hot summers day ;D
I did run it for a bit, burping the air out, but will admit, did not keep cap off the whole time. Put it back on when warming up.
-
That's where you've gone wrong, cap stays off until it's hot :y
-
I might do this before my drive home, get it hot with cap off, before setting off.
Might look like a bit of a n00b reving the car with bonnet up in the multi-story at work, but ahh well ;D
-

Surely your new nipper is now old enough to to change a stat. :D ;D

Bet that Kirsty Gallacher would give you a hand burping it ::)

Don't rev it, just left it warm up naturally at idle... key is heater temp on Hi to ensure a full supply through the matrix and fan on its lowest setting so as not to draw too much heat from the coolant :y

Fair enough :y
Although from experience it takes the 4pots feking ages to heat up. :)

My little 1.4 would sit there all day without the fans kicking in. Don't think I've ever heard them.

Do they actually work? ::)

Why wouldn't they? It's not a 15 year old banger you know. ;D

Currently sat in the car, as predicted taking ages to heat up. Normally have to rev it a bit to get it to warm up. If it does not lift off end stop in next 5 mins, i will be asking it to heat up a bit quicker ;D ;D

Typical yoof... no patience ;D

Well it kind of worked. Got it to 85/7c. Never going to get fans on, when car is on top floor of a multi story with wind blowing.
Popped cap on, left work. For about 3 miles stayed at 85c, then dipped down to 79c where it stayed no matter what. Heaters hot max, cold max, stop start traffic, 40/50/60/70mph all same speed.
It did finally pick up to 85c when I came off the motorway, stopped and pulled away at lights. Then through town it stayed at 85c. :-\
One thing I've not tried thinking about it, is run on petrol, not LPG. Might have to try that....

Dash reading correctly?

Dash reading correctly?
My code reader thing appears to have stopped working, so can only assume so.

Best you fix it then. Takes the mess of wind pissing out of the equation ;)

Time for a new thread on that. Need to get a dedicated one, the cheapo mobile based one has been unreliable.
-
when i did my 2.2 as advised on here..cap off...heat set to high..no blowers on..left it running burping hoses as I went along and fans kicked in a few times,,took about 45 minutes and when heat came through,,realy hot,cap back on and took it for a run and was great heat....since then heat died down so flushed again and results were good...however now need to flush the whole system again with stat out then flush with water and then flush matrix separately ..then refill with antifreeze and then run it all up again.. :y :y
-
Heat is always fine :y
Today it refused to go above 75c for most of my commute, yet there was plenty of heat! Went up to 80c after leaving motorway and in traffic. Never hit 85 but traffic was kind today, less stop start.
Ordered a new code reader. So shall see.
