So i've been noticing that my 98 gsr doesnt heat up all the way. I changed out the thermastat so that's working fine. I'm even running a jrsc at 8psi but for whatever reason it's just not heating up all the way i'm at about 30% on the tempature guage.

What's the problem

 

30%... isn't that's where it's supposed to be at? 1/3 of the gauge... correct me if i'm wrong.

 

It will be damn near 1/2 with an OEM thermostat. When you replaced it, did you go with an OE?

Did you properly bleed the coolant system after you replaced the thermostat?

 

yeah i had it done professionally with the oem one. I think the fan is coming on to early and not letting it heat up properly
