Verify the vehicle’s HVAC configuration before ordering, especially on 2001-2004 applications noted as compatible with select models lacking air conditioning. Confirm the rear position and compare the original unit to the Spectra 99265 before installation. Flush the cooling system and inspect hoses, seals, and related HVAC components during service to help prevent repeat contamination.
