just wondering what temp degree of t stat is everyone using?????

89Laredo

195, same as factory...

canadian88xj

ok sweet does your temp guage say its running at 125?

Trev1006

176 but I have cam and such

89Laredo

no... Thats way too cold.
I run 210 with no fan shroud or electric fan no matter what outside temp it is.

Should be between the 2nd and middle line.

Trev1006

Your therm stuck open by chance? Hows the heat?

canadian88xj

oh ok i thought my guage was ****ed. it goes from 40 (cold) to 125 (hot) and it sits at max thats normal then??

i have a **** ton of heat

tjwalker

99% of 4.0 applications should run a 195 degree thermostat.

Buy your stats directly from Jeep for the best reliability and STABILITY of coolant temp.

I buy plenty of aftermarket parts. I buy my thermostats directly from Jeep.

89Laredo

Ahh... you have the metric gauges.
That too hot then. lol

It should never go much over the line in the middle of the temp gauge.

ohh ok so i prob bought a bunk t stat then ?

89Laredo

Could be alot of things, did it stay at the right temp before you changed the tstat?

I would never let it go above this red line:

canadian88xj

no it kept boiling over out the resevoir. i put a new tstat, new rad, new water pump, new hoses, new tem sensor, and new reservoir cap on it. it doesnt boil over anymore but it def runs hot

tjwalker

There CAN be some inaccuracy between the coolant temp sensor and the dash gauge.

I always verify using an infrared point and shoot thermometer pointed directly at the thermostat housing. That gets you close to the actual coolant temperature.

Don't want to be chasing a ghost.....test.

yeah true will try that out
