well... I tried installing where the OEM tempatue sensor is screwed in the Koyo Radiator and just falls in because the Thread is to small.. you guys know if im connecting it where its suppose to go..???? I can say these Amber Gauges look beautiful

 

There is no OEM temperature sensor on the radiator. Are you talking about the one on the top of the rad? If so that is the coolant level sensor and you want to put that back ASAP. The instructions show you a crappy way and place to put the gauge. They want you to drill and tap threads into a pipe and cut out a section of your rad hose to fit that in. Pretty bad place to put it since if your tstat fails you wont know and you'll overheat. What thread size is the sensor? If it's 1/8" NPT you can put in the stock temp sensor location on the block.

 

got a PIc, i need one ASAP????

 

Pic of what? The coolant level sensor? It's right on top of the rad in the middle. If you're talking about the stock water temp sensor its right next to the stock oil pressure sender under the oil filter pedestal.
