Coolant Temperature Sensor stuck

[boostedgst523]

Like the title states, my coolant temperature sensor is stuck. I've tried a wrench, penetrating oil, and vice grips and it still won't come out. I've been battling with this sensor so much that I stripped it a little. Is there any other way possible to remove the coolant temperature sensor? Any advice and tips are appreciated. Please help

Have you tried a ratchet with a socket on it? That will give you alot more bite/torque than with a wrench or vice grips. Maybe putting a little heat on it with a propane or mapp gas torch would help break it loose.

Try heat depending on where the sensor is, be careful about using too much heat. after you heat it take a non scented candle and see if the wax will wick into the threads.. Dont over do it , just a little wax.

Unfortunately, it's too stripped to get a ratchet with a socket on it. I didn't have deep sockets that's why I tried the other ways.

I'll try to heat it as you both said and I'll get back to you guys
Thanks for the quick replies guys.

I tried everything advised and I ended up stripping the $hit out of it . I have no idea as to how I'm gonna remove the sensor. If worst comes to worst, I think I'll just have to buy the lower part of the thermostat housing (if that's even possible). Other than that, I'm clueless.

Try a good pair of vise grips.

Try a good pair of vise grips.

i ended up tapping the sensor lose with a hammer and vice grips. Took quite a while because the sensor kept stripping off the cts. But got it out

Best thing to do with a stuck bolt, sensor, etc... Heat the area AROUND the bolt (or whatever), until it gets good and hot. Not red hot if you are using oxy-acetylene, just too hot to touch, and try to keep the heat away from the bolt. Yes, some heat will radiate to the bolt and heat it up too, but not as much. This will make the hole expand. Next, spray the bolt/sensor with penetrating lube, and let it sit for a while. Between the expansion of the hole, and the adding of the penetrating lube, it will break loose. You may have to do it a couple times, but it will work.

Junkyard trip + new thermostat housing. Just add gaskets!

Would this work on over tightened bolts?

on an overtightened bolt, you would want to heat the bolt so it would grow longer, this would loosen it a little so you could take it out...
