Longish post – need your help.
2003 Explorer Eddie Bauer 4.0 l live in NW Washington
178247 miles
rebuilt transmission and transaxle in July
Back on August 6, I was heading to Doctor for job mandated physical. 1 mile from appointment the gauge zooms up to max temp and light comes on. Not much choice, I continued to appointment. Explorer is now spewing coolant to the extent that someone called the fire dept. AAA took the rig and me back home. Found the thermostat housing had a lovely hole out the backside. Replaced housing “Dorman” (it was available) complete housing assy with thermostat and cover. For next 2 weeks had occasional overheat on gauges but then quickly went back to normal. Coolant drained and vac’d back in a couple times. 50/50 mix. Another trip, this time the overheat didn’t go back down. Scanner shows 325 degrees. AAA took the rig and me back home. Found Dorman had provided a thermostat that doesn’t always open. Replaced with Motorcraft thermostat 180 degrees. Rig now runs (usually) at 192 . Rig has been on dozens of 40 mile +trips and a couple 200 + trips without any overheat problems. Last Thursday rig shows overheat that wouldn’t go back to normal. As I was almost home I just drove it. Block tester shows yellow. Next steps ?
