2003 Buick Century Question: repair heater core
Answer #1Oakman January 05, 2010, 11:43Master
If the heater core in your 2003 Buick Century is clogged or leaking it should be replaced not repaired. There is an access panel on the lower side of the heater box on the passenger side which must be removed to access the heater core. You may find the specific service information you are looking for at the AuoZone website - www/autozone.com.
