Thermostat?

That little red light that indicates low coolant keeps popping up on my dash. I topped it up but it keeps comin back. I'm 90% sure that its not leaking, and also the car takes ages to reach normal running temp. It must be the thermostat yeah? Stuck half open or somefing.
Just wanted a second opinion.

Re: Thermostat?

yeah its the sesor on the coolant resivoir (spelling). Its like $40 to replace or you can get rid of it or...maybe its just dirty. Mines does it all the time but i dont notice it anymore i just always check my temp guage

Re: Thermostat?

that's the stupidest idea i've heard... if he replaces it, then it will actually warn him of coolant loss and possibly save his engine in the future...
if he pulls the light out of the cluster and a hose busts, he wont know about it till the temperature guage hits red...

Please don't do that !!

I agree with Menco, its probably the sesor on the coolant resivoir, not a major problem, just keep an eye on your coolant levels until you get it fixed.

Re: Thermostat?

is the sensor in the EF similar to EA/EB?

i was always having trouble with the sensor sinking causing the coolant light to come on in my old EA.

Re: Thermostat?

If it's slow to warm up and is losing some coolant you may need a new radiator cap.

Re: Thermostat?

The floats on the sensors have a bad habbit of cracking with age.
they get very fine cracks in them and over a little while they fill up and just sink.
I bought a new one the other week for $50.
