How to install a temp sending unit on your Teryx (pics)
What's up guy's?
I installed a temp gauge on my 08 teryx and thought I would show how I did mine.
If you take your engine cover off you will see your thermostat housing below the shiffter on the passenger side. If you look on the front side of the lower section of that housing, you will see a boss that looks like the same one that your factory hot light switch is threaded and screwed into. Remove the radiator hose & top of the housing (you will have a small amount of coolant loss), remove the thermostat.
Center punch the boss shown and dril out the boss. Make sure to go slow and keep yourself square so as to keep your hole in the center all the way through until you reach the inside of the housing. Tap it with a 1/8" NPT tap (check your fitting for your drill & tap size). Clean any shavings that have made it into the housing out. and install your fitting. Be sure to use thread salent on the threads of the fitting. Now just hook up your wire and run to your gauge, your done!
You can leave the housing in tact, drill your hole, (the drill bit will remove it's own shavings as you drill) put grease on your tap and this will keep most of the shavings out of the housing then you can remove the factory fitting and use compressed air and blow through both holes and clean it out that way. Easier, but not the best way but it's your machine!
