Omega Electrical and Audio Help / Rear Speedo and ABS Sensor

« on: 26 October 2013, 15:15:57 »

Dear All,

having problems with intermittent loss of speedo and ABS/Traction control warning lights coming on. Think this is possibly the rear near side abs sensor playing up or similar. Was looking to disconnect and clean up connections but need some advice as to where and how the plugs come apart. Can the cable be physically pulled off the back of teh sensor for cleaning or is it disconnected further back at a multi plug? Any help or tips/pictures would be of great assistance.

Regards

Omega General Help / Re: Coolant Leak at rear of Engine

« on: 29 March 2012, 19:04:49 »

Had a guy with a camera on this and it seemed to be a pipe leaking. Have changed the HBV already and checked as much as possible without having access to the crowded area low down at rear of the engine. I  will try and get some more definitive info for you guys to analyse.

Omega General Help / Handbrake problem

« on: 03 September 2011, 21:00:09 »

Dear All, handbrake on the omega travels a long way before the car holds. Is this an easy adjustment? Is there an adjustment or should the slack be taken up automatically. Any advice would be most helpful.

Omega General Help / Cam Belt Change and Assistance

« on: 29 August 2011, 11:37:52 »

Dear All, following on from previosuly described cooling problems, should it become necessary to change the water pump on the car i was thinking that it would be worthwhile changing the cambelt at the same time. I understand some members of the forum do assist with this kind of work. I am fine doing basic mechanics but wondered if anybodycould assist should this need doing and what sort of charge i would be looking at getting an "expert" involved. I live on the outskirts of Peterborough, Cambs. many thanks in anticipation of any advice.

Omega General Help / Re: Cooling Problems and Servo Vacumn Pipe Query

« on: 29 August 2011, 11:31:18 »

Have changed HBV and thermostat but no change in situation. Car drives fine on motorway with temp at about 94-96 degrees. temperature climbs when i hit traffic and fans then cut in at around 98 to 100.Just a bit concerned that car is running too hot. From earlier comments it would seem the water pump is ok as car drives fine for a number of miles without really overheating. So looks like a radiator efficiency issue perhaps. Have flushed the system as per the guide and no sign of any oily sludge. have had k-seal in the system to stop a minor leak previously. Just wondering whether it is worth changing the radiator. Any thoughts/advice welcome. Cheers

Dear All,
many thanks for your input. I am going to try and repair the servo hose for the time being. I have managed to get some parts (elbow bend specifically) from the local vauxhall dealer for a couple of pounds.
With regards teh overheating the only other thing i have read on the web about is the HBV as a possible cause for pressurising teh system. Anybody had any experience of this ?

Omega General Help / Cooling Problems and Servo Vacumn Pipe Query

« on: 23 August 2011, 10:53:17 »

Dear All, my 2.5 V6 engine temperature gets very hot. Runs at over 95 most of the time and when in traffic up to the red line. Fan is working fine (thankfully). This has been a gradual change as car used to run on 90 all the time. I have flushed the radiator but this made minimal difference. I am looking at changing the thermostat or water pump. Is it more likely to be one more than the other?
I also have  adamaged servo vacumn pipe. It has two "t" pieces in it. I am having trouble sourcing one from breakers etc. Is there a suggested parts person who might help before i go to the main dealer? Many thanks in anticipation of any advice.

Dear All, thank you for your suggestions. Paper clip test has been performed both with car running and switched off. The only code that shows is a 12. I believe this is the code that indicates the start and end of the diagnostic run. Will take on board the suggestions and try changing the crankshaft sensor and also look at the timing belt tension. Cheers
