- 2002 Expl 4x4 XLT 4.6L
Hello everyone, thanks for sites like this. My vehicle: 2002 Explorer auto 4x4 4.6L. 120k miles. I had oil on my oil filter, found thru sites like this it is probably the gasket behind the housing. I switched it and everything looked good, so a few days later, I replaced the upper rad hose and the thermostat. I put in the new thermostat and then wrapped the o-ring around the upper housing and assembled it. I idled it for a while and all looked good. Came home the next day and saw coolant on the ground. It's dripping coolant even though the vehicle has not been driven since the day before. When the engine is on, there is pretty much a steady stream of coolant leaking. Took it apart, bought a new o-ring and this time I just dropped in on top of the new thermostat, bolted it together, still have a steady coolant leak. I had no coolant leak before this repair. Any ideas what to do?
