The question is Phil, are you sitting with a satisfied smile on your face and heat in the car, or is your matrix and engine sitting on the floor having disolved under the attack from scalding acid.

Elf and Safety will be scouring the countryside for shifty looking Omega owners clutching tins of orange sherbert!!

PS..  I shall be trying this at the weekend cos we don't have Elf & S in Peckham.

Phil .. my reason is quite simple ... if you are flushing through constantly with a hose .. the water will be cold, so the thermostat will be closed. The water you flush with will clear the radiator and the main pipes very quickly, but with the thermostat closed as the system is "cold" the main engine block and the heater matrix, which are both "inside" the thermostat loop, will hardly get any water. By doing what I suggest the system runs to temperature, the thermostat opens, and the whole system has the water mixed ... so a couple of cycles of this and the system is clean.

Just my thoughts... nowt else ..

Quite right Entwood, I bow to your superior Intellect and Knowledge

Car OK, all Aly bits OK, acid mix is  designed to be safe at the described concentration 
As for Elf n Shifty, we don't do it here, we use common sense
BTW, if you do have a go, bear in mind what Entwood says about the final flush, he's quite right

Just an update to descaling the cooling system.
The cabin heat is now spot on!, the problem I had with occassional overheating into the red zone followed by the needle dropping to below 75deg.  is now a thing of the past & the temperature behaves as it should now, thank goodness Also, the EML has gone off and STAYED OFF for two days now!!!! Before, it would come on for no discernable reason during a run and after I cleared the code (always P0170 Lean Exhaust) it would return on the next run. All problems now gone, hopefully never to return. I think the old girl is getting to like all the attention I am lavishing on her and repaying me for my efforts

That's exactly the type of thing you should NEVER say when you've got an Omega, trust me

Hi Philrich.
How do you clear the codep0170 from the system, and any chance of a drive across to you to take a look at my heater problem.

Russ.

Hi Russ, you could come to mine next Monday or Tuesday anytime after 10am? or failing that, we are having a meet of local members on the 28th at 12noon at 'The Windmill' , formerly the Dalton Lodge, on the Southbound A19 between Hartlepool & Billingham.  PM me for contact details & arrange things?

has anybody out there got a oxygen censor to fit a 2002 petrol 2 litre omega 4 wires that they can sell to me.

This has been an interesting thread Russy - aside from your current request, can you tell us how you got on with the heater problem.  Were you able to get it fixed?

[russy]

Hi Zulu77.

the omega baron philrich was great and worked on my car and the heater is now working i would say at 80% a great effort and a major improvement .
although now the car is lumpy when first started for about 1 minute i have had camshaft centre sensor replaced but no change and i believe it is the oxygen sensor with the help of the AA patrol service advise.
so anyone got one they can sell me at a reasonable cost also any advise on removing the old one the nut seams very tight.

Thanks Russ   I'm glad that you had some resolution to the heater problem - lets hope you can get the present one sorted without too much difficulty
