1996 Vauxhall Omega MV6 3.0
A high perfromance motorway muncher!
The car has just started to overheat last week. I've checked the obvious, including the water levels, water in the oil as possible head gasket failure and fan operation. All seem normal so I'm not sure - any ideas???
The engine management light flashed on for a second last week, but has not come on since.
The car is booked into a garage next week to try to identify problems.
Exhaust manifold has little crack and is blowing a small amount.
Seems to be a problem with any radio I fit- I have tried two so far. If the volume is above a certain limit, which varies, the unit seems to keep cutting out and re-setting until I can get the volume down to a very low level.
This is an ex City of London police car and has been serviced every 13 weeks before I got it. I have replaced the interior with a leather one from a later model which was scrapped.
Not sure if police tweaked the suspension as it handles like a dream and is fun in the wet due to the rear wheel drive.
Lovely car to drive and super smooth.
Would you buy another car from this manufacturer? Yes

Regarding the radio, its possible that it has the Bose sound system in which case the output of the radio is fed into an amplifier. Hence only line level outputs of the radio should be connected to this, and not speaker outputs. Its possible then you are overloading the amps with speaker outs of your radio, use a radio with line outputs or remove the power amplifiers.
I have an Omega GLS 2.0 16V auto, no problems ever with overheating. Check the fan is working OK (its very quiet!) and that the radiator is not airlocked. Also check water pump as they can easily go and take the timing belt with them! Should sit at around 95 (mid gauge) most of the time. Also check thermostatic switch is working OK.
Reference the problem with the stereo; I think it will be highly unlikely that it has anything to do with the Bose sound system, as only the 3L Elite came with this. The police spec MV6 is basically an Elite with all the luxuries taken out, and so would not have had the Bose system in.
