Heater Core: Initial Inspection and Diagnostic Overview
SYSTEM INSPECTION
1. Look for evidence of coolant leakage at the hoses or heater core attachments.
2. Check the system for loose heater water hose clamps.
3. If a leak is found and the heater water hose clamps are tight, check the heater core tubes for distortion or evidence of being bent out of shape.
Severe distortion of the heater core tubes could cause leakage at the heater water hose connection.
