I finally got my 70 cougar out after a 3 year nap...been starting it on and off in the garage during the big sleep.
Took it out on the road and she roared back to life. Drove for a while and then it started to overheat. 351 Cleveland with automatic - no ac. Replacement 24 inch radiator and original fan shroud and blade.
Checked the following.
Removed thermostat - flow going through radiator.
Flushed out the fluids - Prestone valve in place and ran it for a long time.Water is crystal clear.
Drained radiator through lower valve - clear water running through.
Water pump is nice and quiet - replaced three years ago also.
I could not get the lower block plugs removed so did not get that done.New freeze plugs put in three years ago when block was detailed.
WHAT COULD THIS BE?
WHAT SHOULD I DO NEXT BEFORE TAKING IT THE LOCAL GARAGE.
TRYING TO SAVE A FEW BUCKS WHEREVER I CAN.
