Might have to go down this route - where would you get the dye etc?

« on: 14 January 2020, 21:48:09 »Another area, is on the top left side of the Radiator. It can have a airline crack in it, but the coolant can go down over the week. I had the same symptoms on my Omega, (it is a 2.6), As suggested on here, removed the plastic cover, over the radiators then pressurised the coolant system. The leak could be seen then. Replaced the radiator no coolant low warning since. Except when HBV went.
Already replace the radiator, so possibly rules that out.
The HBV is looking a possibility from what's been said, coz also, last year i went through a phase where i couldn't get any heat into the car, but temps were normal.
It then suddenly started working again about 6 mths ago. Hmmmm ;-)

I'm putting about 1.5 litres in every week.
Also, the expansion tank was new a couple of years ago.

I hope not :-) He's been looking after my cars for over 20 yrs now.
Just have to wait and see what he says.
One more question though, as i said, I'm refilling the coolant every week with 50/50 mix of antifrees (costing me a fortune). Do you think that, as long as I keep an eye on this, I will be ok to carry on running the car as normal? Don't wan't to cause any damage if i can help it.

Indeed it does have to be going somewhere.
I've had a pressure test done on it and that came back normal.
I've also got it booked in with my mechanic again next week to try to find out what is going on.(He seems to think it may be vapourising somewhere internally)
Although it doesn't fill you with confidence when he asks you what will i do if this is terminal

Have also experienced a leak at the rear end of the transfer pipe on the drivers side of the Desmond. In both instances, you're looking for evidence of coolant at the back of the engine between the steering box and starter.
It could also be the head gasket, but you don't describe anything re than coolant loss, so start with the simple stuff first
I really appreciate your thoughts.
As far as i can tell, there's no mixing of coolant and oil (gunge on oil filler cap etc) which is, i believe a sign of the head gasket failing. Also i had the gasket replaced about 12 months ago.
I don't see any physical signs of a leak left on the road under the car, so my question is, could the HBV still be the problem even without leaving a stain under the car?
Again, thanks for you ideas.

I need help !
I've got a 2.2 CD (Z22XE).
Had timing belt done, New water pump, new thermostat and new radiator.
There are no leaks that can be seen anywhere.
However, i'm having to refill the coolant bottle EVERY WEEK when i get the check coolant level warning.
I've had a pressure test done on it and that's coming back fine.
Does anyone have any thoughts as to where my coolant could be going.
Thanks

Underneath, you can see the brackets, and the sensor plug (ignore the extra wires I have in the same area, that's all LPG stuff)
All done!
Simple when you can see what to look for :-)
Thx again

Thx very much.
I assume that the sensor connector is part of the said bracket.

I'm trying to work out how the coolant expansion tank on my 2.2 yx22e is secured to the car, before i decide whether swapping it out as the sensor is buggered is a job for me or a mechanic :-)
Can anyone give me any tips?

Omega General Help / Re: Flushing Heater Matrix
« on: 20 March 2018, 13:10:18 »
OK, sorry to be a pain over this :-)
Is there any special procedure for removing these connectors from the heater matrix, or is it just brute force?
I have done the following..
1. Removed the small green ring
2. Unlocked the locking ring and pulled it back.
After this nothing wants to move. So, is there anything else that needs to be done to get these bloody pipes off :-)
