What It Helps Fix

• Weak or no rear heat from the HVAC system
• Coolant seepage from a failing heater core
• Restricted coolant flow through the rear heater circuit
• Fogging or sweet odor caused by heater core leakage
• Uneven cabin temperature in rear-seat areas

Installation Notes and Tips

Verify rear-position fitment before installation and compare the original unit to the Spectra 94783 for hose routing, case shape, and connection layout. Drain coolant before removing the old heater core, and inspect hoses, clamps, and the HVAC case for wear or contamination while the system is open. After installation, refill and bleed the cooling system according to the vehicle service procedure.
