HEAT ODOR
POSSIBLE CAUSE
1. Radiator and/or air conditioning
condenser is restricted, obstructed
or dirty.
2. Electric radiator fan not operating
when A/C is on.
3. Engine is overheating (heat may
be transferred from radiator to A/C
condenser). High underhood
temperature due to engine
overheating may also transfer heat
to A/C components.
1. Has a diagnostic trouble code
(DTC) been set?
2. Coolant level low.
3. Obstructions in heater hose
fittings at engine.
4. Heater hose kinked.
5. Water pump is not pumping
coolant to heater core. When the
engine is fully warmed up, both
heater hoses should be hot to the
touch.
1. Various heat shields are used at
certain driveline components. One
or more of these shields may be
missing.
2. Is temperature gauge reading
above the normal range?
3. Radiator fan operating
incorrectly.
4. Has undercoating been applied
to any unnecessary component?
5. Engine may be running rich
causing the catalytic converter to
overheat.
CORRECTION
