2002 Temp Gauge Skyrockets In Prolonged Idle and Coolant Gurgles at Shutoff.
So my 2002's temp gauge will creep to the max if I idle for any period after running for more then 10 min or so. It also will idle rough sometimes, (jump between 800 and 1500 rpm.) When I shut it off I hear a gurgling sound coming from the radiator/coolant reservoir. My reservoir level is slightly below the MIN line and dosent move even at full running temp/redlining gauge. I was thinking maybe its just a low coolant issue? Or a thermostat problem? I have a 270 mile roadtrip on Monday and need to figure this out ASAP.
