Hi folks,

getting mad while trying to change the temperature sensor from idiot light to Rally pack. Totally stuck in the block. Meanwhile its complete "round", even with big pliers no movement. The sensor is now completeley f*cked, as in the end the material broke. Any idea? Used already tons of WD40. Will it help to try it again with a warm/hot motor or....?
Any suggestions are appreciated, at the moment I am very close to take a big hammer as I am now in the 6th month restoring the car and one problem is solved while two new appear...it starts getting frustating.

Thanks,

Marc

 

Pipe wrench.

 

Try PB-Blaster. The stuff works miracles. Spray around threads once or twice a day for a about a week, then try the pipe wrench mentioned by don71. But you have to give the PB Blaster time to work. If you cannot find PB Blaster, a home-made version can be mixed from transmission fluid and acetone. Check out this video link:

Good Luck!!

 

Should be in the intake manifold. There's likely a lot of build up/corrosion around the threads on the bottom side, so if you can't get it out with the sugestions above, maybe try something like CLR to dissolve as much of that as you can. Might require pulling the intake, though.

 

the pb blaster is good....use that and put a torch(propane, mapp or acetylene propane will take more time) on whats left of the sensor get it nice and hot around the entire bottom and some vice grips to unscrew it

 

I'd break it off and put a little heat on it with an easy out.

 

X2 on don '71's pipe wrench suggestion. If the sensor is rounded off, a pipe wrench can still grab it and have a good grip on the body on the sensor.

 

X3. Pipe wrench.

Heat will help, too, but, of course, watch out for flammables, including wires, hoses, and gasoline.

Be careful not to cook anything. Penetrant oil and the pipe wrench is a good first start.

 

ATF/Acetone kicks *** ... but not in this case. Heat to glowing red, then a properly adjusted pipe wrench will spin that puppy loose. It's a water tight joint so I wouldn't spend a lot of time trying to get a liquid to wick down it ... it's not gonna happen.

 

Use visegrips with rounded jaws.
