Product Details

This heater core is used in the vehicle’s heating system to transfer heat from engine coolant into the cabin air stream. For 2007-2010 Toyota Sienna front HVAC service, Spectra 99313 provides a replacement option for restoring heater output when the original core is restricted, leaking, or no longer transferring heat efficiently. The part number 99313 is also referenced in interchange listings for related aftermarket applications.

Common Issues It Can Address

• Weak or uneven cabin heat in a Toyota Sienna
• Coolant odor or moisture from a leaking heater core
• Reduced defrost performance caused by poor heater output
• Restricted coolant flow through the HVAC heater core
• Heating system performance loss in front HVAC operation

Installation Notes

Verify the vehicle year, make, model, and front-position fitment before installation. Heater core replacement typically requires access to the HVAC case and cooling system, so the cooling system should be drained and refilled according to factory service procedures. Inspect hoses, seals, and related HVAC components during service to confirm the repair addresses the source of the heating issue.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control processes are used to produce heater cores that meet or exceed original equipment performance expectations.
