This may qualify for the "gremlin dept"....
1972 Chevy C-10 2WD, 250/six, standard heater (no A/C).
Within the last two years (20,000 miles):
New Radiator (proper OEM core)
New Heater Core
New Radiator & Heater hoses
New T-stat (195 Stant)
Rebuilt Water Pump.
Engine comes up to operating temp within 10 minutes and stays there.
Drove to work today (1/2 hour trip), ambient air temp about 15 deg F. Heater blew not quite luke-warm air the whole way.
Got to work, left truck idling, opened hood, felt hoses: both were quite hot; heater still blowing cool/cold?
ANybody know how good the '67-'72 heaters were in the first place ?
(Hoping not to have to pull the heat box again; gotta pull the right-front fender-well to do that...
)
