I'm sure this question has been asked and answered before but here goes;
What is the thread size/count for the coolant temp switch on a 1990 YJ 4 Cyl.
I am finishing up the final parts of the SBC swap, since I am using the stock gauges I am going to drill and tap a hole for the stock coolant temp sensor in the edlebrock intake. I thought it might be 1/8 NPT but no luck. Help is greatly appreciated.
