4.6. New fault appeared yesterday, happened again several times today. The car drives normally but when left standing, it cuts out completely after a while. It's an electrical cut out, instant. The temp is fine and aux fans are fine. This happens approx every 8 minutes of stationary tick over.

After leaving it a while it restarts. If I leave the bonnet open, it's fine. It wont do it when it's getting movement cooling.

Something appears to be suffering from heat soak, but what? I'm suspecting a relay, but someone may already have covered this issue.

I've searched but found nothing.

Thank you if you can be of any help.

It will be the crank sensor, generally as they get warm with heat sink from the motor they fail. Good news is, easy to fit a new one and cheap part to buy.

Thanks guys, I've just realised that the aircon fans are not working either, related do you think?

No error codes btw

The condenser fans, which is what I think you mean when you say "a/c fans". Are considered ghost fans by many forum members because they don't usually come on. I see mine turn on from time to time. Using a scan gauge I see that they usually come on when the coolant temp is at 210F and cool it back down to 199F and then kick off. The viscous fan clutch seems to do a pretty good job coolant the entire system alone. I NEVER see them turn on in the winter :) .

I live in tropical far north of Australia and I've only seen mine cut in once or twice in the last 4 years. Our average summer temp is 36c and 90% humidity. I still believe the cutting out problem will be the crank sensor.

ps if you said that the blower fans (inside the car) were faulty I would have suggested that you check the fuse box :thumb:

DOH! Forget that, they are fine. I was talking about the A/C blower fans, not the condenser fans. I was thinking about fusebox problems but the original crank sensor must be it, I'll replace that. Thank you so much guys, I would never ever have found that, will let you know.
