I replaced my thermostat, rad hoses and ECT sensor last weekend. All went well until I tried removing the old ECT sensor. It snapped off at the head, leaving the body and threads inside the block. I finally got it out by drilling a hole in it and using what is laughingly referred to as an "easy out." (It is neither "easy" nor will it always get it "out.")
Checking for solution on line, I found a LOT of people break off their coolant temp sensors in the block or heads. Being a bit gun-shy so to speak, when I installed the new AC Delco temp sensor, I was VERY careful. There was a fair bit of teflon tape on the threads from the factory and it didn't screw down as far as the old one. It was getting tighter and tighter, to the point that I was worried about breaking off the new one. I finally stopped before the wavy washer made contact with the block.
I will monitor it for leaks but I don't really want to go through all the hassle again to tighten it if it doesn't need it. It is a tapered thread; there are several turns of Teflon tape on the threads and it is tightened to about the right spec (even if it didn't tighten down all the way.) I have done lots of plumbing, and I wouldn't tighten any tapered thread fitting more than I did.
Anyone else experience a new sensor that didn't go all the way in? Did you ever experience a subsequent leak?
Thanks
