Heater Core: Notes
CAUTION:
Spring-type clamps are installed as original equipment. Installation and overtightening of non-specification clamps can cause leakage at heater hose connection and damage heater core.
NOTE:
Inspect for evidence of coolant leakage at heater hose to heater core attachments. A coolant leak in heater hose could follow heater core tube to heater core and appear as a leak in heater core. Check integrity of heater hose clamps.
