Hi all,
At 205,000 miles my 3FE suddenly started overheating. It'll run fine for 20-30 minutes at normal operating temp, then spike up and when I pull over coolant is overflowing. I replaced the radiator, cap, hoses and fan clutch 5000 miles ago. Note- apparently a certain idiot (me) didn't install the brand new thermostat sitting in my parts kit, been running the past 5000 w/no thermostat. First thought was an air bubble so I flushed the system 3 times with distilled, refilled with distilled/Toyo red, issue continues.
Obviously head gasket comes to mind, but:
Thanks in advance!

Obviously head gasket comes to mind, but:
-oil is clean, no coolant, changed and checked
-coolant is clean
-tested for exhaust gases in coolant, negative
-no white smoke
I'm leaning heavily towards water pump, looking for other ideas before I disassemble the girl. If I do the water pump, aside from the obvious (all hoses) anything else I should do while I'm in there since fan clutch is practically new? Going to pull the radiator for access and rebuild the PS while I'm at it.Thanks in advance!
