## Questions & Answers

**Q: How do u find out if this fits your vehicle? I have an Oldsmobile Bravada (GM)**
A: I made it work.  You are gonna need to know the size of hole and thread size of your water outlet/thermostat housing and then see if the switch/sensor matches those dimensions.  I have an 1983 K20 that I installed a dual fan assembly from a dodge charger into and wired up this control to my trucks thermostat housing's temperature switch.  Yours is probably different and will require some homework to wire it up--hint:  hotrod forums are great for research.

**Q: how long in warranty last.mine has stop working**
A: Idh

**Q: Does this have a hi and low modes or just on and off?**
A: Just one setting. I used it for about two months with a dual fan setup but kept having issues so I built a relay pack.

**Q: Whats the thread size of the probe?**
A: 1/8 pipe (1/8 NPT)
