I have a 4.2 in a 2000 E150. after 15-20 mins. driving, temp guage goes up. No fluid loss, and burping & running heater to dissipate heat helps. Cool nights not as serious effect. Radiator, pump, & thermo. changed by previous owner. I changed fan clutch, 2nd thermo., cap, & pressure washed condensor and radiator. Door chime continues after driving starts, ABS light on after driving short time, & oil temp light comes on with rising temp guage. It powered down the first time I drove it a distance and had these problems. Limped it back and above work done since. Have seen the posts here but nothing relevent since first of the year and no solutions. Anyone with fresh ideas? Cool driving weather you don't see as much.
The 4.2 runs great but does get a little rough running as temp goes up. Are there any coolant flow valves I'm unaware of? All lines heat up & heater & air works. Read about sensors for temp guage & computer but no changes yet.
