my temperature is still rising on my guage. i want to replace the coolant temp sensor. I am getting the coolant light and i am wondering if that could be my problem, one of the wires. At advanced auto i am confused on which one to get as there is two any help would be appreciated.

 

The coolant temp. sensor, the one thats located in the drivers side head is for the gauge and it has one wire that connects to it, the sensor in the water pump has two terminals.

 

It is not clear, but if you are getting a low coolant light, it has nothing to do with the two previously mentioned sensors. The low coolant sensor is on the radiator and commonly goes bad. Or maybe you just have low coolant.

 

i am sorry i did not make it clear enough. i am getting a low coolant light. i am also still geetting to the very hot range on my guage which is why i believe its not my gauge thats reading wrong but rather the sensor on the waterpump that is allowing it to get that high?

 

I'm pretty sure I posted Rob/Shoebox's link for you, on how to test the sensor accuracy. Lot cheaper to test than to replace.

 

can u resend the link i cant seem to find it.

 

Click on "How to's" in Rob's signature.

 

update on this problem i replaced both sensors and now the car is running a lot cooler now and the fans actually kick on as soon as i start the car. i believe the problem is fixed but only time will tell.

 

The fans should not kick on when you start the car. They should only come on with the AC, or when they coolant temp exceeds 226*F.

 

what should i do to fix this? and the heat is on but idk if that activates the fans?

 

Heat position will not activate the fans. AC or defrost function will. Fans running at startup is usually due to a trouble code. Most common cause is a blown fuse for the AIR pump. But there are other codes that turn on the fans.

 

ok so now my temperature is slowly but surely rose to about the last white hash mark on the temp gauge. is there anything else i can do to combat this? i guess i could turn on the a/c but i would rather not have the a/c running constantly.

 

It does this with the fans running from startup, never shutting off?

 

well i did what u said and put the a/c relay back in and the fans stopped turning on at startup and im back to square one. the problem is back with the fans not coming on.. i replaced all the sensors and properly bled air out via shoebox guide.

 

i might of installed the wrong thermostat what do u guys think?? left is new right is old.
