FUSCH Engine Coolant Thermostat Housing Assembly for Honda Accord & Element 2.4L (2003–2011) – OE Replace 19301-RAA-A02, Metal/PPS

FUSCH Engine Coolant Thermostat Housing Assembly replaces OE 19301-RAA-A02 to regulate coolant flow and help maintain optimal engine temperature for Honda Accord and Element 2.4L models.

This replacement thermostat housing assembly is engineered to match the fit and function of the original unit used on Honda Accord 2.4L (2003–2007) and Honda Element 2.4L (2003–2011). Built from reinforced metal and PPS polymer, and sealed with a nitrile rubber O-ring, the assembly delivers corrosion resistance and thermal stability under typical automotive operating conditions. It’s supplied ready to install and tagged with the equivalent part numbers 19301-RAA-A02 / 19301RAAA02 for straightforward identification.

How does this thermostat assembly affect engine performance?

The thermostat housing directs coolant through the thermostat so the engine warms up efficiently and avoids prolonged cold operation or overheating. Maintaining proper operating temperature helps the engine run closer to its designed efficiency band and reduces wear over time.

• Direct replacement for the original thermostat housing with correct mounting points.
• Thermally stable PPS and metal construction resists deformation at high temperature.
• Nitrile O-ring provides a secure, oil-resistant seal to limit leaks.

Is installation straightforward for a DIY mechanic?

Yes — the assembly is manufactured to match OE fit, form, and function so it installs using the factory mounting locations and hardware. Basic mechanical skills and common hand tools are sufficient for most installations, though a service manual or torque specifications are recommended.

• Comes as a complete housing assembly — no separate thermostat or gasket required unless specified.
• Compatible with factory hoses and clamps on listed Honda models.
• Replace coolant after installation and bleed the system following vehicle procedures.

What materials and construction features ensure durability?

The housing combines high-strength metal with PPS (polyphenylene sulfide) polymer to balance toughness and heat resistance. The nitrile rubber O-ring resists oil and coolant exposure to maintain a leak-free seal over many heat cycles.

• PPS polymer offers dimensional stability at elevated temperatures.
• Metal reinforcement at critical mounting and sealing surfaces for long-term reliability.
• Nitrile O-ring engineered to limit coolant seepage and resist oil contamination.

Which vehicles and part numbers does this unit replace?

This FUSCH assembly is designed as a direct replacement for Honda part numbers 19301-RAA-A02 and 19301RAAA02. It fits the Honda Accord 2.4L from 2003–2007 and Honda Element 2.4L from 2003–2011 when used in the stock cooling system configuration.

• Replaces OE: 19301-RAA-A02 / 19301RAAA02 for quick cross-reference.
• Confirmed fit: Honda Accord 2.4L (2003–2007); Honda Element 2.4L (2003–2011).
• Sold as one complete thermostat housing assembly in the package.

Who is this for? The FUSCH thermostat housing assembly is intended for owners and technicians servicing Honda Accord and Element models with the 2.4L engine who need a cost-effective, OE-compatible replacement. It’s suitable for DIY enthusiasts comfortable with basic cooling-system work, independent repair shops that require reliable aftermarket parts, and fleet managers maintaining older Honda vehicles. For best results, verify part numbers and vehicle compatibility before purchase, and follow vehicle-specific bleeding and torque procedures during installation.
