Product Details

What It Helps Fix

• Weak or no cabin heat in a 2001-2005 Lexus IS300
• Coolant odor inside the vehicle from a leaking heater core
• Fogging or film on the windshield caused by HVAC coolant leakage
• Restricted coolant flow through the heater circuit
• Temperature inconsistency from a failing heater core assembly

Installation Notes

Fits 2001-2005 Lexus IS300, heater core. Verify inlet and outlet pipe size, core dimensions, and HVAC housing layout before installation. Because heater core replacement often requires access through the dash or HVAC case, compare the removed part to APDI 9010457 before reassembly.

Quality Assurance

Built with aluminum core and tank materials for a replacement HVAC application. Confirm fitment against the vehicle’s year, make, and model before installation.
