cutting out
 

I have a 2002 chrysler voyager 2.5 crd and recently it's started cutting out. So far it's happened 4 times. I've noticed that it seems to happen as soon as the needle touches the half way point on the thermostat. I waited 10 minutes and the thermostat dropped just below the half way point, the car starts and drives fine. This seems to happen in heavy traffic only (I drove to Birmingham from London and back and had no problems. Needle remained below the halfway point whilst going at speed). The last time or happened I turned the heater on full and this keeps the needle to the quarter mark...no cutting out. My mechanic is telling me the connection is coincidental and has changed the cam shaft sensor (was showing a fault) but it's still doing it. ... I really hope someone has some ideas as I don't want the whole engine to go. This is my first ever thread so I hope I've done it correctly.
Ps ... when it cuts out it turns over normally but does not fire/catch

Under normal conditions the needles should remain beneath the halfway point unless its very hot and you stay in a traffic jam for a long time.
So my best guess is that your thermostat and/or fan(switch) is failing.
But that still doesn't explain cutting out of the engine. The combination of the 2 possible errors would lead me to the suspicion the fan or fanswitch creating some sort of electronic failure causing the engine to cut off.
So I would check and and eventual replace:
*Thermostat (see: https://www.chryslerforum.com/forum/...-broken-23454/ )
*fanswitch
*Fan

Disclaimer: My suggestions and ideas are based upon a (very) basic auto mechanical knowledge and in this case not on my experiences with Chrysler technicals. :cool:

thanks
 

Thanks...all ideas welcomed. I'd like to be able to give my mechanic lots of food for thought.

in any case check out the thermostat trick in the link I provided, that trick can save you a lot of money if your stat is broken.

Cant remember who got the credits for that brilliant idea, was it Leedsman?

Don't forget than when Camshaft fault comes up to also change the crank sensor as they both work together.
From your description you have a faulty sensor or wiring but I'd go for sensor. It's known that sensors loose their waveform when hot and on way out.

Thanks guys....I'm taking notes.

hmmm... I mentioned Leedsman in my post, and I suddenly realize I haven't seen him in a while.. last activity 23-7 :confused:

- agree Vmaxxer
- where is Leedsman ?

He's got no right to go on holiday without a dispensation from the Doctor...
