Is there a sensor that reads the level and if so where is it ?

ibrahimx2001

i doubt it it might be something to do with a sensor on the fan??

when i bought my car that light was on, it sort of flashes on and off randomly. and sometimes stays on for days. he told me it was something to do with a box of wires under the car near the passenger wheel.
Not sure if its true i had a look at the commections and they looked ok so i ust left it.

Let us know how you get on with it matey.

doesnt this relate to a fault with the engine cooling system electronics? does the fan run all the time?

sri-scotty
14-08-2011, 19:05
thats the wording i couldnt think of, haha.
my fan doesnt run all the time though. just normal.

Thermostat?

Ya my fan is running all the time... =[

yeah, its either the thermostat or cooling control module.

I dont know much about the G but it might get you started off on the fault.

1.4 Astra G
14-08-2011, 19:23
Yeah I took out the thermostat and put it in boiling water and it's not opening ...
Would that cause the light to stay on tho ...?

blink
14-08-2011, 19:27
i think so. it might also be on as you have taken the air con condenser out as the module controls the compressor, fans etc.

if you know the thermostat is knackered, replace it, they arent that expensive, you dont want to have the engine overheat.

is the light amber or red? cant tell from that picture. on the H, some of the lights start amber and go red oil warning for example.

Yeah mate my thermostat was at fault, it wasn't working right and one day I overheated my engine as the radiator was frozen in winter! After the whole overheating/ explosion of coolant under the bonnet and a good drain and defrost, I changed the thermostat and it worked fine again.
A good indication that your thermostat isn't working properly is the engine seeming to take forever to bring the temperature gauge on the scale and up to 85-90. That, and you don't get any warmth from your heaters when you have them on.

comes up as air con:sus: i agree with blinkturbo i go for module
if the thermostat is stuck open no problem if your on the motor way temp will drop to cold, so it could be stuck shut, my dads g its been stuck open for years but no warning light on

blink
14-08-2011, 22:10
he has taken his air con condenser out, so thats probably the cause

still want to sort the stat though

might be worth looking for aircon fuses and pull them out worth a go

Cheers lads
I've been routing at it all evening aswell as spraying my engine cover yellow =]

But no luck the fan is running constantly and the Amber light is still on?

blink
14-08-2011, 22:49
as said, the code indicates a/c fault, and the cooling control module controls that too, so thats probably the cause of the warning light

mikephillips
14-08-2011, 23:34
have you had a look inside th module to check condition? it sonuds like ac fault

1.4 Astra G
14-08-2011, 23:38
Does that module just control the a/c ? If so could I take it out 4 gud?

blink
14-08-2011, 23:44
nah, it controls the cooling system, so the fans and stuff for the engine

1.4 Astra G
16-08-2011, 01:17

A faulty thermostat will ping up A/C fault codes - when mine went I had 4 A/C related fault codes.

Get it replaced and it should be fine (Y)

went to toppart and collected the thermostat tofind outi need the thermostat housing aswell ... =[ ... so i ordered the new thermostat kit and and it turned out to be 2.50 more for the housing aswell

ask if anyone in your area has "opcom" or a fault code reader ....but the warning lamp means a fault in the cooling modual ... if you removed the condensor did you remove the wiring off the pressure switch on or near the condensor {right side } no sensor in circuit will cause a fault .... i honestly dont think your thermostat will cause this if the temp is norm ..... if your engine gets too hot you get a red w/l picture of a thermometer
the aircon system has a dedicated fan on the front of the condensor in addition to the fan behind the water rad the modual wont like this removed either good luck

ok got everything sorted after all ...
wrong part kept being ordered (shops fault) and the housing and thermostat worked out to be €60... light on the dash is off and the fan isnt running constantly anymore =] happy days ......
