Re: Coolant hose diagram
Generally, its the small hose, 5/8 inch diameter, from intake next to thermostat housing, to smaller nipple on core.
Then larger hose, 3/4 inch diameter, to water pump nipple being horizontal on pump.
All on engine are pass side.
Feel both hoses for warmth.
If both warm, then temperature door in heater is not working.
Does TEMP lever have resistance when moving?
If not, check lever behind panel is not broken and also check movement at other end of cable on heater.
If all moves, door may have become loose from its axis.
Is there air moving in other positions? DEF, FEET, DASH?
