2008 Dodge Grand Caravan Overheating.
Van overheated 4 months ago... coolant
overflowed. Mechanic changed radiatior
and problem never really went away.
Temperature gauge never sat at 12 o'clock
always about 10 o'clock unless it started to
overheat. Fan has never come on. Bought
a code reader yesterday. It said I had a
P2121 and P0118. Changed the
thermostat today but same problem
exists!! Temperature gauge sometimes
moves wildly. HELP!! Please and thanks.
(It's already cost over $800).

I would purge all the air out of the system. The P2121 code is for the gas pedal position sensor.

Hi thanks. Sorry I've been drowning my sorrows! The codes are P2181 and P0118.

Try testing the ECT and possibly replacing. That's the p0118

Thank you. That's exactly what I've just been researching. I appreciate your help.
