Omega General Help / heater - rear saloon vent always hot

« on: 18 September 2007, 19:24:03 »

I have a 2.2 petrol saloon and the front heater/demister/air con all work fine, but whatever temp is set on the controls on the dash, the rear vents, (at the back of the centre arm rest), are always hot. On a warm day when the front is blowing cold air we have to have the rear vents closed as the air coming out is hot, even when the air con is on and working in the front! Very annoying for the kids in the back.

Anyone got any suggestions please? [smiley=2vrolijk_08.gif]

I don't believe it!

I was really worried about the way the car was running with the new sensor in, so I cleaned the old one up by wiping it down with white spirit, and put it back in, thinking at least it was running OK before, even if the light was on on the dashboard.

Guess what? When I put the old one back in everything worked fine! Performance was back to A1 and all lights on the dashboard go out straight away! I have given it a run to see if it comes back on, but as yet I have not been able make the control light come on again.

I can only think that the old one was getting a bit grimey on the face of the sensor which goes next to the cam cog. Having cleaned it with White Spirit and removed the grime it seems to be working fine!

On the one hand, I am pleased it is working OK now, though I am not sure if it will last, could be days could be years.

On the other hand I am annoyed that having paid a lot of money for a new sensor and done the work to fit it, it doesn't seem to work properly.

I will keep an eye on it for now and see how it goes and whether the light comes back on. I will also see if I can get my money back on the sensor on the basis it didn't work in the way it should.

Many thanks to all who have given their time, trouble and wonderful advice.

Hi TD.

It is the one in a cogged circle which is the Auto Trans light.

It was fine until I fitted the new cam sensor!

I have fitted a new gasket but the only plugs I had to undo were the cam sensor itself at the front and the plugs/coil unit at the back. Other than that it was just a case of 10 nuts on top, 2 nuts holding the coil unit in place, 3 spring clips on the hoses and 2 nuts on the front cam cover to give enough room to remove the cam sensor nut.

I have done 40 miles this afternoon and they won't go off at all! The cars feel a bit lumpy, is sluggish and wont rev over 4500rpm.

I dont think the excess oil is an issue because the engine revs up ok without misfiring so I think the plus are fine.

I have fitted the new cam sensor this morning (Sat) and all looked fine.

When i checked it af ter completion all the lights went out and every thing ran OK.

I checked the oil level 'cause I am going on hols next weekend and added about quater of a litre as it was in the middle of the marks.

When I went to go out in it about half an hour later,  the Exhaust Emmissions light, (looks like a little engine), and the other one which is an "!" in a square in the panel under the radio/clock, refused to go out after starting. The car is sluggish pulling away and in neutral won't rev above 4500rpm. I have stopped and started it a few times and run it for about 2 miles to see if it would go out, but so far no luck!

Whilst fitting the new cam sensor I noticed that the 2 rear plugs had oil at the bottom of the hole they sit in, (I assume the gasket wasn't sealing too well), so I mopped as much up as I could with kitchen towel and then removed the plugs, cleaned them and replaced them. Inevitably some oil will have run into the cylinder, but I thought this would burn off in a short while anyway. I fitted a new gasket with the can sensor anyway so if the old gasket wasn't brilliant this would cure the problem.

Anyway when I finished the job everything was fine - engine ran A1, all lights went out on the dash, so I went for a well earned cuppa. As I say, I went to use it 30 mins later and the other control light is now staying on!

I am desperate as I am supposed to be towing my caravan with this next weekend or the kids won't get a holiday!

Any suggestions please?

It may be sad - but I'm extremely grateful!

I will sort one from the local Vauxhall Dealer in the morning - and thanks to everyone for all the help!

I have seen new cam sensors on EBay from as little as £8.88 plus P&P.

Are they any good as they seem very cheap compared to Vauxhall prices.

Any idea how hard they are to fit?

(Have to say - this site rocks!! The speed of responses and the helpfulness is outstanding!)

When starting, if the light stays on, it does turn over a few times before starting and doesn't pick up quite as quickly, but after a few seconds it seems to run OK.

If the light goes out it starts immediately and revs fine from the start, but it often comes on whilst moving, though it doesn't seem to affect performance when it does.

It does seem to pull away ok even if the light is on.

I will see if I can find a local garage who can give me an readout of the code/s.

Many thanks

Thanks for the response and help anyway.
I am new to the forum - do you know anyone I can contact or will someone contact me via the forum?
I am not sure how it works!

I have a 2002 2.2GLS petrol saloon with 71k on the clock.

Over the last 9 months the little car & spanner dashboard light, (control indicator for engine electronics according to the owners manual), has started coming on more and more frequently.
When I start from cold it is fine for ages, but when I start from warm it often stays on.
If I stop and turn the engine off, turn the ignition on and wait for the lights to go out, the restart the engine it usually goes out. When do this it sometimes stays off completely, but lately it is coming on again whilst driving.

Is this a common occurence and what do I do sort it. I am a good DIY mechanic and can fix most things - it is just that I don't know what the problem is and I can't afford to pay a Dealer a small fortune to tell me what is up before telling me it will cost another small fortune to fix it!

Any suggestion please?

Omega General Help / Re: Identification of cooling system part.

« on: 03 June 2007, 17:51:54 »

May I add, it's a common point of failure.

It's job, is to direct coolant in and out of the cabin, dependant on where your temperature controls are set.

This is where the vaccum pipe comes in

Brilliant! Many thanks - I will get one tomorrow and tell the wife to get her overalls on!!

Omega General Help / Identification of cooling system part.

« on: 03 June 2007, 17:03:15 »

Hi guys!
I have a 2.2, petrol, GLS, auto saloon, Feb 2002.

It has developed a water leak and I know where it is from, I just don't know what the part is called!

It is between the bulkhead and the back of the engine, at the top on the drivers side. It is black plastic and has a circular top with what looks like a thin plastic vacuum type pipe coming out of the centre of the top. Underneath this is a thick part hanging down with 2 water hoses attached to one side and 1 water hose attached to the other. 1 of the water hoses comes out of the bulkhead amd immediately curls down and under and attaches to this part. Another of the water hoses is "T"'d of another main water hose and also attaches to this part. I am not sure where the 3rd water hose goes to.

Anyone got any ideas what it is called and what it does, (apart from leak!).

I have had a good look and the hoses look OK, it seems to be leaking from underneath the top, but it is dry either side of the leak point so I don't think it is one of the hoses. It seems to be much worse when the engine is up to running temperature, but whether this is due to temperature or pressure I am not sure.

Any suggestions.
