Dash Coolant Temp

I took care of the oil temps and pressure in another post and this is the dash coolant sender, goes directly to dash, does not talk to PCM.

Since the left and right heads are the same, they plug the the hole for the PCM sender on the passenger side head. Here it is with plug removed:



Stock sender of course has english threads so I used a big fat drill bit and a 3/4NPT tap



and done with sensor installed. dash has no idea it's not talking to an old truck motor anymore.



It works great. Dash says 200, fan comes on, then goes off at a reading of 190. It's dead on with the PCM sensor on the other head.
