Gibby here is the guide for changing the HBV on the V6 engine.The 2.2 is similar I think.Its right at the back of the engine and wiull be awkward.The bottom picture shows the small vacuum pipe on top of the valve which you need to pull off to see if you then get any heat in the car.If you do (or dont) get heat in the car after youve taken it off,post your results here and Im sure more advice will be offered.

Hi sir, so does this HBV usually need replacement or there is something to do for it to function properly? And if it needs to be replaced where could it be bought? Thanks, I wish you good health.

Are the pipes to the bulkhead very hot? If not, remove the vac pipe from the top of the HBV, and see if the pipes get hot.

Hello Sir, hope all is well with you. I've bought all necessary items for the work now, and if weather permit I be working on the car tomorrow. But there is one more thing which I'm not sure of, you are talking of removing the pipe(s) from HBV, but on the link posted to me on how to work around HBV, instructs to drain the coolant from the vehicle, now by removing the pipe from the HBV will not affect the engine during the testing? Sorry if I'm mistaken please advise, I want to be double sure be4 I start working on the vehicle. Thanks, may the Lord bless you for the good work you are doing to me.

You only need to remove the small vacuum pipe from the top of the HBV. This shouldn't let any water out (if it does, you need a new HBV!).

This just forces the HBV into the position where the heater matrix gets hot water.

Gibby.Dont go fitting any new parts until the problem has been fully diagnosed.As suggested,pull the little vac hose of the top of the HBV and see what happens.Then report back.

Good afternoon sir, I'm just coming from the vehicle now. It seems this omega is somehow different because the scuttle is grued to the stripe of rubber attached to windsreen. I tried to remove nuts and clips holding the scuttle but it couldn't be detatched from the rubber attached to the windscreen. Actually I follwed the instructions on the link you posted to me. Any further instructions if possible sir? thanks very much for the assistance you are rendering to me. be blessed.

Hi sir, I tried to remove the scuttle panel today but the windscreen rubber which need to be released was a problem, I wanted to remove it with a flat bladed screw driver but my worry was, if I do that will it be possible to refit it or there is a need to buy another one?  Please advise, Thanks

Have you removed the small vac pipe from the top of the HBV, doesn`t need scuttle removing to do that

I tried to look around but couldn't see the HBV, so I thought removing the scuttle panel could expose it. How could I possibly do it? Sorry for Troubling you sir, please advise.

To the right of the brake master cylinder you`ll see two hoses coming from the bulkhead, follow these across and down and you`ll see the HBV.
In this pic the hoses are removed and a yellow and green length of hosepipe has been connected. Where these hoses are connected is where you`ll find your heater matrix hoses which you need to follow. HTH

Huh, I see, in my car those two pipes are on the other side of the engine, they are running from the bulhead to the radiator in front. However, it seems I have an idea now. Tomorrow weather permit I'll have a go and I will report the outcome. Once again thanks very much Sir, Wishing you a merry Xmass and long life. Good night.

Hi Sir, thus true, those are a/c pipes I noted this evening after coming from work. I tried to  work around but the big problem is the LPG system covering most part of the space. So I think the possible way is to remove the scuttle, and Im planning to do over the weekend. But my concern is the rubber plastic running across the bottom of the windscreen, is it easily fitted back when removed? Thnks once again.

[albitz]

Dont remove it.Just pull it up where the little fixings are to access the fixings and remove them.
