thread size for Coolant sensor

[SimonPK]

I've spent the last day and a half putting my KLZE in and all I have left to do is to finish off the wiring, extend the brake booster and cruise tubes and the reason for my post is to drill & tap the hole for the 3rd coolant sensor which my 93 gs has.<p>I need to know what size the thread is so I can do this - please let me know.<p>By the way getting the axles off was the worst part - I had to cut the nuts off in the end with a grinder!

Its been a while but i think i used a 1/2 in. pipe thread, be sure to stuffa rag inthe coolant pipe.
