My f-150 is leaking engine coolant. Why?
I had a water pump problem so we installed a new pump. After driving for about 100 miles the truck started over heating radically and discharging all it's coolant. I then replaced the thermostat and gasket with a new one, but the problem persisted. A new radiator was then installed, and the problem was fixed. After driving around town for a few days I parked in my diveway and to my dismay coolant was again leaking from what appears to be the general area around or below(?) the thermostat housing. Any suggestions?
