I'm going to be picking up a water temp gauge soon, and I was wondering what range of temperature I should use. Is 100 - 250 deg F high enough, Or should I go with 140 - 280 deg.? Thanks!

 

I think the one I have only goes up to 250 Kraig and ive never seen it go past 190 so I would say 280 would be a little over kill ..........hopefully your engine will never see 280! lol but you know how "expert" my oppnion is lmao!

 

The low number on mine is 100. When I installed my new radiator, the needle barely makes it past the 150 mark at any time...that includes Texas Summer in traffic with A/C on. I would just get the 100-250 gauge.

over 235 your motors quits.....

 

What coolant are you running? Evan's coolant has a higher temp because it transfers heat from the block better. But 250 should be high enough.

 

I dont think you should be running evans with a stock or near stock engine. Heck, if I remember right evans is very corrosive internals of the rotary. And like someone said, if your engine would be FUBAR long before you got up to 280.
