knackered thermostat cause th temp gague overheating light to stay on along with the fan?

22nd October 2011, 22:29

does the top hose get hot

22nd October 2011, 22:39

sure does.

i'm just wondering cause i plugged into it at work and put the code into autodata and this is one of the probable causes. already changed the top sensor but hot air comes out of heaters, but the top rad hose is very very very very hot. to the point you could scold yourself poss lol

22nd October 2011, 22:41

so waters going through the stat i reckon its worth a try changing stat

22nd October 2011, 22:42

sounds like stat is stuck open also could be a air lock in water system from when you changed the sensor

Yes it would although not on a saxo it happened to me on an Austin metro.

its possible but id be suprised if that is the thermostat, i take it if your working in a garage you know how to test one so just do that, takes about 5 minutes if that.

Problem sounds more like a leak/airlock

Partial blockage in radiator or faulty water pump?

23rd October 2011, 12:51

It wouldn`t hurt to flush the radiator,if there`s hot air from the blowers I wouldn`t of thought there`s too much of an air lock though.

water pump is new just currently got the stat on the hob we'll see if it opens but it has come away from the plastic houseing so i think that maybe the problem.

EDIT; stat opened

going to put the new one in anyway and bleed the system a few times.

keep us posted mate also what car is this for cos dont you have a car your breaking if so pull rad of that

23rd October 2011, 15:05

for my 2001 furio mate, could do but i think that is worse wise than mine as there is oil in coolant aswell. flushed rad again and all clear not a hint of rust/ crap.

23rd October 2011, 15:07

if you suspect your furio one is fucked then flush the other 1 about 10 times till clear water comes out and pop it on see if it works if it does go and buy a new rad

23rd October 2011, 15:15

tbf mate i don't think the problem is with the cooling system it'self more electrical or thinking about it could my gague be fubar'd ? cause it never seems to go above 1/2 way and even with the two sensors dissconnected it still goes up

23rd October 2011, 15:18

im having same prob with my fuel gage could be the earth in the clocks

23rd October 2011, 15:28

hmmmm i think i'll have to take the clocks out then. are they milti- plug type? and could i run a seperate earth to check?

23rd October 2011, 15:31

if there mk 2 there 2 plug and as for the earth im not sure im gonna do mk2 dial conversion on my mk1 so i havent looked into repairing mine

23rd October 2011, 15:33
