APDI 9010542 HVAC Heater Core

Heater Core Overview

The APDI heater core, part number 9010542, is a direct HVAC replacement for Toyota Tacoma applications. It is built with aluminum construction and aluminum tanks to support efficient heat transfer in the cabin heating system.

Compatible with Toyota Tacoma models, this heater core matches the listed inlet and outlet pipe diameters for a proper HVAC connection. The compact core dimensions help it align with the factory heater core location in the vehicle’s heating and cooling system.

Key Features

• Aluminum construction for consistent thermal performance.
• Aluminum core and tank materials for corrosion-resistant HVAC service.
• 5/8-inch inlet and outlet pipe diameters.
• Core dimensions: 10-3/8 in. height, 6-3/4 in. width, 1-1/4 in. thickness.
• APDI part number 9010542 for catalog and fitment reference.

Detailed Description

APDI 9010542 is a heater core for Toyota Tacoma trucks with fitment covering 2005-2015 models and 2016 models built through 08/2015. As the heat exchanger inside the HVAC system, it transfers engine heat into the cabin air stream so the heater can deliver warm air through the vents. The aluminum core, tanks, and construction support efficient heat exchange while keeping the unit lightweight and compact. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Weak or inconsistent cabin heat.
• Coolant seepage from a damaged heater core.
• Restricted heat output caused by internal blockage.
• HVAC performance loss from a corroded or leaking core.

Installation Notes and Tips

Verify the Tacoma model year and the 08/2015 build cutoff before ordering. Compare the inlet and outlet pipe diameters and core dimensions to the original unit to confirm proper HVAC fitment. Because heater core replacement typically requires access to the HVAC case, inspect related hoses and seals during service.

Quality Assurance

APDI offers replacement HVAC components for vehicle heating and cooling systems, and this heater core is built to match the listed application requirements for Toyota Tacoma fitment.
