I think iv narrowed my heat fluctuation down to the cts because my fan stopped working...my check engine light will pop up when the heat rises and I might have smoke and the engine bay doesn't seem any hotter


So what I would like to know is where the sensor is located on a gsr? And if there hard to change/prices!

Please help me out

 

Bump

Anybody???

 

should be in the head near the rad hose. if not then by the t-stat. trying to rember been a while lol

 

Between the vtec solenoid and the distributor. Its black, one wire I believe. Good luck.

 

It is not the ECT sensor, it is the ECT switch, [rad fan switch] two different "units".

It is located on the thermostat housing, where lower rad hose is connected to engine.

Unplug it and jump the green and black leads, if rad fan turns on, replace the switch. 94

 

^ Yes

 

Ok you were right it's the fan switch I have a paper clip taped in there so my fans always on.......but the temp gauge still gos up then comes down so could it just be the sensor or gauge sensor

 

What do you mean, "but the temp gauge still gos up then comes down"???

Up how far and down to what?

Does it go up and down constantly?
If so,^^^ bleed the coolant system.

When was the last time thermostat was changed? 94

 

When my gauge sensor went out it would go to 1/8 past cold at a stop light, then it would hit the C when I started driving again. Just kept going back and forth.

 

It will go up 3/4 the way then come down to normal temp I just changed the thermostat and opened the bleeder just liquid came out no air

 

So is the car overheating you think? You should either get an automotive thermometer or just replace the sending unit for $14 since they do eventually go bad.

I don't think it's overheating my fan is on and it doesn't feel overly hot to the touch the valve cover u can pretty much keep your hand on but it's just nerve racking to see my temp shoot up

Where is the sending unit??

 

Does it stay at normal once it goes there? 94

 

It's stay normal when I first drive it then it will randomly go up then come back to half way and stay there usually

 

Sounds like the sending unit then.

Its the one wire black/yel

 

I don't think it's that I unplugged it and the check engine light came on so its working right???

 

Actually it's the yellow/green one wire sensor.94

 

Would you KNOW if the car was overheating by opening the hood??? I can keep my hand on the valve cover and the radiator hoses they aren't really hot

 

If you can keep your hand on the rad hoses. it's a good bet your not overheating.

A thermo gun is the best way to be sure.

Also, if rad fan "cycles" turns on and off. it is a sign engine temp. is normal. 94

 

I have a paper clip in it so the fans always on I just drove the car pretty far just got home the temp stayed normal idk seems like once the car is warmed up good it's fine but thanks for the help!
