Anyone I use locally?
Not really, I did but he screwed me, then I had another, same thing.
If all you are looking to do is replace the coolant temp sensor it cant be that hard.
Where is it located on the DII?
As for the intermittent, it could be a loose connection.
There is a shop on Chicago Drive in Wyoming that was recommended to me by another DI owner, I forget the name of it, I would know it if I saw it though.

 

Oh I was just wondering in case I had something more challanging.

I think I can get the temp sensor. Its behind the Alt slightly under the plenum, not the most easy to get to location.

 

The alt is easy to remove, the hardest part will be resetting the clock/stereo/HVAC.
If you get something more challenging shout, I can recommend people for big things.

 

Great thanks again for the input.

 

pix of the little rascal, would check plug for corrosion before removing with a deepwell socket over the sensor.

 

I have a 2000 disco II that blew a coolant hose and overheated. Lost a lot of fluid. Didnt know it til red light came on. Shut down and fixed. hose and refilled system but the red light is on and the guage goes all the way hot on start and then off the guage cold with red ligbt still on. Is there a purge valve or is there a procedure for purging the system? Next thing I will try is cleaning the sensor. I am not a mechanic. IS it difficult to replace the sensor described in pre ious posts? I have it sold and want it fixed for the lady before she comes to pay me. New to forum.

 

You have air in the cooling system most likely.
It needs to be bled, start a new thread on how to bled the cooling system or do a search, it has been covered alot.

 

I think you need to take the intake manifold off to access that sensor.
Getting the intake manifold off is quite a PITA and will run you into money
unless you DIY.

If you can reach the plug for that sensor - there may be just coolant which has leaked into the plug and corroded the contacts.

With that said - the sensor is a thermistor.

A resistor which changes resistance according to heat.

The Navy did a study (attached) failure rate looks low.

 

Just an FYI, that sensor can be removed with the intake in place. Takes a special socket though.

 

i dont remember a special socket, but i do know i replaced mine with the intake in place. i think i have to shift the ac compressor out of the way.
