Engine Does Not Tick Over When Hot

[elbon50]

Engine starts from cold & runs well, accelerates strongly, etc

BUT

When it reaches full running temperature it stalls at tickover revs

Any ideas please ?

Not enough bypass air getting past the throttle, open the idle air bleed a few turns.

[elbon50]

OK thanks Paul

Will try that

[elbon50]

Yes, opened idle air bleed a few turns

Engine now not stalling when hot

BUT

It hunts between about 1100 & 1800 revs when hot

Changed coolant recently but i think its fully bled out now

Keep bleeding. And when you're done, bleed some more!

Yes I did wonder if it may be that

Don't seem to be getting any more air out

But may be some still in there

Air trapped in the coolant going to the waxstat giving it too much bypass air when hot, as said above bleed it out.

You can test the waxstat as the culprit by blocking off the 5p sized hole inside the throttle body with your finger, the revs should drop to 800-900.

If you know someone with a high lift jack (for 4x4s) then use that, can really raise the back then. Its how I do mine.

Or fit a manual choke then loop off the feed lines to the throttle body as, other than the filler cap, that's the highest point that the coolant reaches in the engine bay. Makes bleeding the coolant a lot easier and the air isn't heated up as much (debatable benefit).

Another tip, when setting the idle with the idle screw make sure everything electrical including lights, blowers etc is turned off. Made this mistake before and revs kept dropping too low.
