Already Tried:
I checked my anti freeze level which was good but it was a little gummy on the cap, I have looked into getting my thermostat changed but its under the intake manifold and a pian to get to, and Ive held a thermometer up to the heater vent after its ran for a good while and it only blew about 102 deg. inside the vent.
