Installation Notes

Verify the vehicle year, make, model, and heater core position before installation. Compare the original unit to HT398357C for inlet and outlet layout, case fit, and HVAC configuration. On GM van platforms, access to the heater core typically requires removal of interior HVAC components, so confirm the exact application before disassembly.
