Any help would be greatly appreciated!!!
Have you checked your coolant level? Also if your gauge isn't reading hot, maybe you have a bad sensor.
Also check your water pump and see if it's seeping coolant. With the engine off, loosen the belt and spin the pump pulley by hand and see if it's turning freely.
Maybe the RCM is bad as well?
