Has my thermostat had it?

[DrR]

Temperature gauage has started to wiggle about abit, when rolling down hill can see it dropping, only about 2 nothces.

When i did a track day while back i must have cooked something, because harder i accelerated the gauage went right down!

sounds more like a fault with the temp sensor or related wiring. Either that or you're really low on water or have a huge airlock

 

[DrR]

Hmm can't imagine it being low on water, it's not chanaged in 18k.

A : Is there water in it?
B : Does the heater work?


If all above answers are yes, its just a renault and its fine!

 

[DrR]

yeah water is half way between min and max, never moved since i have it.

Pretty sure the heater still works to, i'll check next trip out.

 

[SBV116]

[DrR]

when it's the watertemp sensor and it keeps playing up then it will eventually also make the car run a lot worse. The ecu will think for example it is still running cold and limit the revs , like mine always does a bit of kangaroo-ing when on cold.

I've heard/seen cases where the tempsensor was faulty and the car ran like when cold , bit of spluttering etc.

Car has twice not let me go over 2800 revs when cold, just dies.

change the sensor . It cured a LOT of likewise problems
