i want to install my water temp sender in the location of the stock sender for the cluster. only thing is i dont know the thread specs of that hole. can i assume it is the same as the oil pressure sender (1/8" BSPT) ?
I don’t think the stock temp sender location is 1/8. I think it’s 3/8".
But I could be wrong.
If there isn’t any coolant in the block just take the unit out and see
what the size is.
