thermostat area leak

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...

OP has a V6 not V8, just don't know OHV or SOHC.

Good catch, I didn't notice.

If you have never done so, for the price, i would go ahead and get a thermostat a gasket and change them. Along with the housing if it is indeed the plastic one. Also save yourself a headache and get a motorcraft oem Tstat. If you have a heater core line running to the housing go ahead and change that to while your there. Shouldnt be more than 40-50$ From memory there isnt alot there to leak coolant other than the housing/hoses.

Welcome to this forum! A cooling system pressure tester is a good tool to have. You could connect it after you made a repair on the cooling system to pressure test everything so that you don't find out while driving. Autozone loans them if you don't want to buy one.
