Title: oil temp in red?
Post by: D3f1anCE on 29 July 2012, 12:15:34
hi guys got another issue i hope you could help with? after nearly 5 weeks off the road due to needing a new crank case sensor and no tax...i finally got my 2.5 v6 elite auto back yesterday in time for a family trip out...whilst stuck in traffic i noticed the oil temp dial was shooting up into the red section whilst the car was stationary and when in motion it was hovvering around the 130 degrees mark . i got the car off the road as quickly as possible and gave it 5 hours to cool down but it did it again on a second drive that day!i have also notice that it keeps needing me to check coolant level and top up,yet i have never seen any trace of water dripping from the engine?i have noticed a minor oil leak around the bottom of the gearbox and sump...any ideas ? do i just need to buy oil and top it up? or is it something more deadly i need to address? :o

That will be coolant temp.

Coolant leak in the v of the engine perhaps?

No oil temp on the omega so it will be the coolant temp  :y

If your loosing water and can't see any puddles on the floor, you may have a knackerd HBV.
You will find it at the back of the engine (drivers side)

Looks like a flying saucer with 3 large water pipes and 1 small vacuum pipe on it.

Rob will be along with a picky of it in a minute   lol

Around £40 all in from your local Vx. dealer, easy enough to fit but you do need to confirm this is the source of your problems first.

further diagnosis required. Aux belt in one piece? Waterpump in one piece? Stat not stuck? Coolant airlocks?
