I think that's normal for a V6.

Someone will confirm, or contradict ;D

Yes that IS perfectly normal for a 2.5 V6. :y

Engines fully heated up do,  but as long as there is not a strong smell of oil or smoke/steam showing anywhere, that should be perfectly ok. :y

Monitor it for a couple of days, and report back.

I would Andy.  It is a cheap way of ensuring the mix is right, and it is all as it should be from a date you will be aware of. :y

......in addition Andy.....;do you know when the cam belt / tensioners / water pump where last changed?

If it was 40k miles ago or more they need changing. :y

If you change the coolant, make sure you use genuine VX antifreeze with a 50/50 mix.

Post by: andyroo on 03 June 2008, 17:08:27
will do , cheers :y do you know if you can easily change the air con button and heated seat button on dash as they are worn, also bulb behind speedo gone is that an easy fix :-/

Coolant change will do it no harm at all. you need a 50/50 mix for compleat protection, and as you have no idea when it was done last you should do it. use vx pink coolant and be advsed that if yo drain via the rad drain you will only get about  50% of the old stuff out. so flush out well untill the water is clear, then add about 5.5ltres of pink coolant  to the system. job done. :y

Don't think you can change the buttons.

Have a read through the Maintenace Guide section for changing dash bulbs.

In terms of the dash board bulbs follow the thread in the link below for everything you need to know

http://www.omegaowners.com/forum/YaBB.pl?num=1211046787

As for the switches they are straightforward to replace. :y :y but other will no doubt advise on  the precise details :y

Switches just pull out and can be changed for the earlier hard type not the soft feel they fitted to mini facelift.

But not the buttons??????

 When i mention switches i mean the whole switch including the button part, i dont see any point in taking it apart when they are so cheap and easy to do. ::)

Dash bulbs 10 - 15 minutes.
For "buttons" guess you will need to change the two switches.

If the hot smell you describe smells of burning oil then most likely your cam cover gaskets are leaking oil onto the exhaust...the switches just pop out with a small screw driver blade popping them out, got a couple here if you need em £5 plus postage for the two you need...as said the bulb is easy too...

Normal running temp for 2.5v6 is about 92-95 (the fans cut in at 95 to cool the car back down) engine tends to run hotter at slower speeds as there is less air flow to keep it cool...

Chris made a great point and if you are convinced that it is not a burning oil smell it may very well be coolant from a leaking HBV - I had this exact problem with a 'hot engine smell' burning coolant from the HBV.
Worth a look. :y

hi all
just a quick question, whats a HBV ??? i want to do as much as i can to my omega but as it stands i only really know where to put the petrol an oil lol.  :y

All Omegas should run at around mid-point on the gauge.
Title: Re: very hot engine

My 2.5TD normally runs at around the 95 mark.
However, when climbing hills it'll creep up rather quickly towards 98-100. I've wired-up the two rad fans to run as I need them, but this makes little or no difference to these temperatures.
I've changed the water pump, and also have the viscous fan fitted. The actual flow of water is now first-rate, but I'm worried about towing our caravan. The slightest gradient sees the gauge creeping upwards rather worryingly, though not into the red.
Is all this normal, or should I be trying something else?

At around 97/98 on gauge, the actual temp is 110C, which is the limit of the safe working limit.

About 100 - 120k, these BMWs started to silt up rad.  Check the rad is not partially blocked.

My TD never goes above 96 on gauge, got it up to 97 racing up the passes in the lakes ::).  I do not have viscous on.
