I have a 1999 Dodge Intrepid 2.7 L DOHC that continues to run hot. I have replaced the thermostat, fans, relief value and have done a radiator flush.
After I have had these things done the car does fine for about a week then back to the same old crap. I can drive about 40 miles in the morning time nothing happens. In the afternoon about 20 miles then the temp gauge starts rising so I turn on my heater for about 5 minutes till it goes down then turn the ac back on for the next 20 miles home and does fine.
If I turn the car off for about 10 minutes or less then crank it back up the temp gauge jumps way up there I sit and let it idle till it goes back down on its own without the heater.
If anyone has had the same problem please let me know what you did to fix it.
