i replaced the coil pack on my 2.2 at the weekend, while that was off, i decided to pop the throttle body off, in doing so i had to take the coolant pipes off.
Lost maybe a 1/4 cup full.
Re-fitted it all and it works fine, but on the way to work i noticed the temp was running at a constant 81 rather than 85.
I changed the thermostat a while ago, and it previously ran bang on at 85 all the time.
I never released the cap on the coolant bottle when doing the throttle body, have i introduced an air lock in the coolant system, which is causing it to run cool? :-/
-
not sure for new models, but 81 C seems really low to me..Mine normally stays at 92-93 .. :-/
-
Wouldn't an air lock make it run hot?

Remember pre and facelift gueges show differing caliobrations. Mid guage is the best marker.... :y

Have you been on the 65o proof again? :-/ :-/

4 pots run cooler.
85 is the centre of the gauge for me, thats where its supposed to run.

90 is the centre of your gauge.
What temp does the engine ecu say its running at?

:o My 4 pot runs at about the same temperature as my dads v6 :-?

No idea, guess plug it in tomorrow?

Facelifts have different gauges, but 4 pots should run at 85, V6 at 92

Sorry, promise I haven't been drinking (thats a porkie), but for some daft reason thought you had one of those elm based laptop readers...

Both should be (just under) midpoint, and seeing as 90 is the midpoint on facelifts, 92 is too hot for the V6 (fans should be on at 92C), and low 80s tooo cold for 2.2

With the brand spankers thermostat it sat at 85c all the time. Until i popped the throttle body off

85-90 sounds right for 2.2...
not sure why you are reading low now

I am thinking air-lock / bubble? :-/
Or i hit the temp sender, as thats near the EGR :-/
-
I'm thinking poor connection on the temp sensor, but that normally causes gauge to bounce about. Thats why ecu reading would be handy...

Gauge was moving fast, i thought it was stat.
From cold it went to from 0 - 85
Stat opened
Dropped to 80
Raised to 85 again
Then dropped to 80, raised slightly to 81, stayed stable.
-
it ran hotter today, on a steady run it smoothed out and sat at just under 85. shall see what it does on the way back, but it seams to have fixed itself :)

Dyslexic fingers! ;D ;D ;D
Gist of post is correct though. Pre and post facelift numberings are different although needle deflection is the same....

Ok its confirmed as running cooler than normal. Got a tech2 plug in, the gauge is being accurate.
After i changed the stat some time ago, it would always sit at 85c on the temp, driven hard or soft, 60 cruise or 80 cruise always sat at 85c.
Today on the way home it was reading 79/78 at a 80mph cruise.
Spanking it away from the roundabouts i managed to get the temp to 85c, but as soon as i eased off, the temp dropped back to 79.
Now i got the temp from 79-85c very quickly, and it dropped just as quick.
It was 79 when i entered a housing estate, doing 30mph for a little bit (30 seconds) temp raised to 85c, then within 10 secs dropped back to 79.
Wtf is going on?
At the weekend i cleaned the throttle body and used a new gasket, cleaned the EGR. Coolant level is ok, using Vx Red.
Only new component was the coil pack, thats brand spankers from Vx.
Any ideas!?

My omega temp gauge always sits at around 80, had the thermostat changed around 2-3 months ago, genuine part, just thought this was normal for the 2.2. :-/

can you tell if the fan , esp high speed fan, is coming on when it shouldn't?
-
I can't tell when driving as 4pots only have 1 fan. but when stopped and left idling the fan stays off. only thing I can think of is the coil pack. its the only new element. I might switch them back
-
Don't you have an AC fan in front of the radiator?
and (at least on the V6) the big fan behind the rad is two speed which should be temp dependent.
I guess its no big job to switch DIS pack on the 4 pot so I guess its worth a try, but I can't figure why that would make a difference. Why did you change it originally?
If the fans are behaving , it starts to sound like the stat is sticking, even though its pretty new.. :-/

Stat is less than a year old, coil pack changed due to slighly occasional miss-fire at low revs, it just was not pulling as well as it should.
-
Shouldn't make any difference if the fans running as it's the Stat that stops the car getting to cool and will do even if the fans are running flat out.
Looks like it's the stat, after reading this I've changed my stat again, put a orginal 1 in around 3 months and gauage sat at 80 as i said before, new stat in today and it now sits a 85.
Probably the stat as can't see anything else affecting it as long as it's all been bled okay.

Its just odd that the temp dropped just as i did that work, as the day before it was running fine! :-/
