V6 Xantia......... the beginning of another adventure

[Trainman]

Right, thanks chaps, I whack the LEXIA on it tonight when I get home and see what it says...... Thank you

[Trainman]

Further update, Lexia wouldn't connect...... And by the time I'd sussed out why it was to late to messing, turned out to be a dodgy USB port.

Anyway, I checked the hoses and they seemed to be OK with the top one getting warm, however, when I felt the radiator it was stone cold. I had the car running from cold to normal running temperature, fans came on at about 70 degrees and I had no warning lights, as soon as I closed the bonnet and began to drive off the water temp light and STOP light came on....

Annoying is the only way I can see that mini adventure ending hopefully the issue will be solved with the next session without a load more grief Steve

[Trainman]

It's driving me nuts Will,I'm going to have another go with the Lexia in the morning..

[CitroJim]

Steve, did the radiator eventually get warm?

[Trainman]

Steve, did the radiator eventually get warm?

No Jim, car got to normal running temperature and rad still cold........

[KP]

Could be a dead stat thats blocked then and causing the sensor warning to come on as it knows the engine should be much warmer than that.

When was the coolant last changed in it?

Also where is the vaporiser plumbed into in the cooling circuit as they take a lot of heat out of the water??

[Trainman]

I managed to get the LEXIA on it this morning, the only ECU it showed as "talking" to was the engine one and this had no faults...

I decided to try something a bit stupid, when the car up to the normal running temperature I unscrewed the pressure release on the rad to see if there was any air in there, there was a bit but nothing major..... the surprise was that the coolant that came out was lukewarm....

So, im beginning to would if you could be right Will. It's strange for it to suddenly go though, or is it?

[CitroJim]

Vapouriser is normally plumbed into the heater matrix lines Will..

It'll be worth bleeding the system Steve. It's really easy, open the rad valve with the engine not running until coolant issues from there very freely. Then remove and leave off the expansion tank cap and start up and then remove airbox (standard first step in any V6 job!) and when the engine is up to temperature open the bleeders - two brass Allen headed screws one near the green coolant temperature sensor on the top hose casting and the other on the thermostat body.

If that does not make life happy then it'll be a good idea to swap the 'stat as Will says. Nice job for Paul that...

[Trainman]

Thanks Jim, your a star, it's having a service tomorrow and I've just picked up the matrix, plus the exhaust has arrived. Hopefully she should be a happy bunny soon.....

[Trainman]

Right, then I've had the engine bay apart, well air filter removed, checked the flow of water from Header tank to radiator, all good, got the car up to temperature, opened the top hose bleed screw got hot water, opened the other bleed screw, nothing..... no air, no water just nothing......

[myglaren]

Water pump?

[Trainman]

I'm so frustrated with it at the moment, everything was fine until the other day now I'm getting to the point where I'm wondering if I should have bought it.

I don't want to feel like that, I love the car........but.......

The one thing I have noticed is the the LHM is low, so I'm wondering if that could be giving me a false reading on the STOP light, I will call and get some LHM this afternoon on my way to work. Then see what that does tomorrow.

[citroenxm]

What about leaving it for a week at the fellas place in north wales and seeing if he can sort it all out.

Not saying he can.. but he might be able to.. have a chat wil kp i think he did it.. not sure if he is happy with the service or not though..

[Trainman]

I'm more than happy to do that, although I've heard he's a bit of rouge......

I'm going to sort out the LHM in the morning and then make a decision
