Cooling Fans

[Gary406]

no. if you disconnect the sensor they run constant.

[tadunce]

Yes, when you disconnect sensor fans start immediately. Even car key is in your pocket.
Nobody can tell me where the problem is.. I have changed relays and sensor.. No effect.
When i am in a traffic jam, temperature little by little raises up and i have to turn AC on

Sometimes, when the air is taken from the inside the car, not from the outside, fans start without AC..

@Gary - any luck yet chuck?
@Tadunce - is that the only other sensor you've tried, one from the scrap yard?

[tadunce]

You want to say, that a "new one" can be broken too?

[tadunce]

And more..
Mates have said that 2.1td fans goes to the second level of working in about 100oC.. 97oC i think. Am i right?

[Gary406]

ordered the sensor today from dealers.

£24 +vat so bout 30 quids.

is it easy changing this ?

[tadunce]

Yes, its very simple.
Take a wrench in your hand, take off a brown wire and spin sensor counterclockwise. Take a new one ant spin it clockwise. Put on brown wire and you are done here

[Gary406]

thanks mate .

[tadunce]

And you should disconnect battery, because if you take off brown wire, fans will start immediately

[Gary406]

changed my sensor today.

no1 mentioned the coolant squirting 10 foot high did they

me and my 7 year old got soaked wet through in anti freez when i took old sensor out.

taudance. it is the one on the right isnt it ? i had a blue one on the left and browny red one on the right ?

hope ive changed right one

[Gary406]

well it apears on service box that the blue sensor should be on the right and maroon (brown) sensor on the left.

but mine is oposite. doesnt really matter i supose . both in same place (coolant)

[Gary406]

does any1 know what the blue one is for ?

my fault was definately the brown one. i only touched it with my finger and the fans kicked in.

anyway ive just rang dealers and ordered the blue sensor as well. may as well do both temperature sensors

[tadunce]

Brown is on the right.
And there was no problem to change it to me, who could even think about you became wet

"Taudance" - you made my day, mate

[Gary406]

i just guessed your name there mate sorry

i'm gonna change the blue one as well. apperantly dealers said that is for your engine temperature

[tadunce]

No problem ;)

Can it be, that blue one send information of temperature to your dashboard?
Or is it for different reasons?
