as i was coming home tonight dash lights dimmed then failed warning lights all came on then car overheated any ideas? battery is now flat.

Auxillary Belt snapped is my guess.

id say its the fan belt snapped, or pulley given up, seeing as it drives the waterpump and alternator

thanks people guessed somthing like that just too cold to be looking tonight!

Agreed on this, no drive to alternator, or waterpump points to auxillary belt fubard.   :(

You must have carried on driving for some time to have flattened the battery.
Hopefully the cold weather will have prevented too much damage(!).

No mention of flat battery until after the event;

Overheating:  The temperature will rise instantly, as there is no coolant pumping around the engine.

Also, driving for a fair distance is not easy when you have no power steering, and on an Omega, power steering is mandatory lol  :y

If the auxiliary/fan belt snapped, then the first thing you should have noticed is the red charge light coming on, then as you turned off to check, you'd have noticed that you'd lost all assistance of your steering. It would've taken a mile or two on driving for the engine to overheat. As for the battery now being flat, I've no idea. I agree with Brickhead but was trying to be diplomatic  ;)

I can say all this cos all the above happened in that order to me a few weeks ago when my fan belt snapped.  ;) My battery had enough charge to restart my car 3 times as I started it to coast down a long hill on my way home and then start it to drive it up the ramp of the recovery truck.  :y :y

had no warning apart from dull dash untill temp light came on i stopped and it failed to restart.

got a good look today and yes the belt is gone anyone recomend a good place to order a new one?

Send a PM to AndyC, he is a Vauxhall parts manager and will supply the belt at Trade Card prices for OOF members.

PM or email AndyC details:

thanks very much thats appricated :y

You need to investigate why the belt went as well because it will just throw the new belt if the cause isn't rectified! Is the tensioner siezed? Water pump?

any help with water pump location please!
does this belt affect timing at all?

anyone?

There's a diagram in this thread:

Tried to copy/paste it in but it wouldn't do it....

No effect on timing.    :y

guess the tensioner is done! should i be able to turn it by hand? i cant

Bearings are siezed then. Ask andyc when you ask about your aux belt :y

If you update your profile with your location maybe one of us can help  :y

is the tensioner an easy fix?

You just want the tensioner wheel with the bearing.  Undo nut in centre (15mm), remove old, fit new and retighten nut  :y  2 minutes!!  Refit belt as per diagram above.

exellent you lot have saved me some serious time before i've even started. ;D
one other question i have a front wheel hub to replace also and have read some silly torque figures for tightening it! over 300nm would i just get away with tight as i can on a 3' bit of scaffhold?

If it really does have to be that tight, use a trolley jack to raise the 3ft Scaff Bar on a very good ratchet and socket, then lower/raise/lower/raise etc until you have reached the desired torque.  :y

thing is cant find a torque wrench that goes that high!

Do the work then ask your local garage to torque it up for you.

A  paperclip test should reveal all:

as kneepad suggests.
code number will further illuminate matters without confusing the issue with engine noises.
