where to find 1/2" temp switch or adapter

[jetfixr]

I did the jeep fan upgrade. Problem is, now I am looking for a temp switch to thread into my head. Currently there is a 1/2" npt plug in the head, but all the temps switches I find online are 3/8", or 1/8" with a 3/8" adapter. Where can I find a 1/2 temp switch?

All you need is a reducer bushing. Should be able to get a bushing and the temp. switch/sensor at NAPA.

any autoparts store hardware store or home improvement store has those type fittings readily available

spend a rainy day in those store lookin in the hardware bins and get familar with readily available local stuff and after a few years you can save yourself hundreds of dollars in useless shipping charges that you spend on dot com

Here's some part #s for the fan switches. I've had really bad luck with Jet and Hypertech. Finally found the sweet spot 180 t-stat 180 fan switch from Hypertech. It lasted less than a year befor the fan switch went bad. Ordered a new one. It would turn on but not off. I am using the SW-505 from AutoZone and the 180 Hypertech t-stat. It comes on a little later than I would like but at least it shuts off. Plus it was only $9.00. I'm going to try a stock 195 t-stat when when I feel like "playing" with it again.
