hey i bought a temp sensor a few months ago the first one quit the second one worked for a few months a went crazy with the rpms and quit that for a few weeks worked fine again and got stuck on hot so i bought a new one again and now this is stuck on cold any ideas?

 

Is the connection to the sensor good? Is the port opening to the sensor have any obstructions?

 

the connection seems good this cooling system is killing me just replaced the thermostat radiator the res and temp sensor X2 could di electric grease help the connection if thats bad? oh and the thermo is bad already top hose hot bottom hose ice cold

 

if you mean both hoses going in and out of the radiator are different temps that's not your thermostat, something is obstructing somewhere. thoses hoses share the radiator.

 

First off what temp sensor did you buy as there are technically 3? One for the fan switch on the thermostat housing (round two pin plug), one on the head (round 2 pin plug that sends signal to the ecu, aka tw sensor) and a one pin plug on the head that sends signal to the gauge temperature. Why did you think it was bad? Was it overheating? Did you bleed the system of air after you did the thermostat and sensor? Upper radiator hose hot bottom cold would indicate thermostat isn't opening but need to know if you bled the air out?

 

i bought the sensor to the gauge cause its gone out three times now and usually its stuck on hot and now its stuck on cold. i just did a system flush and refilled it and i bleed the system and no matter what the bottom hose has no pressure and doesnt get hot im lost as a now the only thing i left left i could replace is the sensor on the thermo housing and the water pump but the top hose still cycles fluid into the radiator
