Thread: V8 coolant temp sender part number

HI J,

throught i was going a bit mad when i started reading ur thread. know how the over fueling feel like the beast has done it and is at moment running very rich (faulty afm, got a replacement one $400) i went through what u r doin and found that my temp sensor was ok. someone years back posted this for someone else with similar problem

the whole page is not bad (its got lots of other stuff as well and the whole site not bad) it has helped me a great deal and still use it to smooth the beast out but i dont mind the extra fuel, love the power it puts out

Thanks Jessie.

I'll do the volt adjustment on the AFM when I get home. When I adjusted it going by ohms the engine was cold.

I have the remapped fuel chip fitted from John Davis so will adjust it to the higher volts and see what happens.

I'll replace the coolant temp sensor anyway as it probably isn't 100% after 13 years of use.

Mine doesn't seem to be using any more fuel than I would expect it too but it has been running like this for months as I can't really remember when it started. However it is still getting decent economy figures.

Originally it spat a little fuel and black soot at startup. You couldn't see it but it would mark the garage door. However I don't know what it did when at operating temp (pre adjusting AFM)
When I got to work this morning I put a piece of white paper over the exhaust for about 30 seconds while idling and it come away perfectly clean. I'll do the same thing when I leave this afternoon.

In my experience, all petrol engines do that.
They have to run rich on a cold start &, combined with condensation in the exhaust, always leave their mark if parked against a wall, door or another car.

always leave their mark

dito here both mine do it, they like a cats trying to outdo each other, but the rangie wins hand down.

Ummmmm welllll so what you are saying is I have fallen foul of a Landy quirk?
Louise's 2004 Corolla doesn't do it although I don't mean to compare a 94 Land Rover to an 04 Toyota

My 97 Rodeo didn't do it either. Well maybe a little bit.

Well I might just replace the replace the coolant sensor (or put it in my Landy parts stash) check the AFM adjustment and leave it at that.

Well if I didn't research stuff like this at work then I would die of boredom

Jessie you can't fine me if I don't go to the meeting either

Thanks guys.

I just finished doing the voltage thing.

It was already on 1.273v and didn't spit anything on start up when leaving work or when getting home.

I cranked it up to 1.5v and it was spitting out the exhaust a lot. So I backed it off again to 1.3v and it spat a little so backed it off to 1.273v and left it at that and it appears fine again.

I reset the ECU between fiddles.

What I find interesting is that I don't really know if the liquid coming out the exhaust is petrol or water. It doesn't really strike me as petrol but if you increase the volts more liquid comes out. So either it is petrol or the higher volts pushes more pressure out the exhaust which spits the water???

Jessie have you adjusted your TPS like in the link? The RAVE says to just bolt up and plug it in
However it doesn't mention anything about adjusting the AFM either.

J,
sure have, had to grove out the holes to make the adjustment, i have also adjusted the throttle disk (butterfly) base idle, and a couple of adjustments. if you need a hand (and that just one as my left arm is out of action) let me know.

other reason that there is a bit of moisture coming out might be due to the v8's running hot at idle and the exhaust cooling causing condensation to come out of the pipe, ie running rich runs hotter more condensation, lean runs cooler less condensation.
and of cause this only a theory
