Product Description

This Arrowhead thermostat housing is designed for the cooling system of select Toyota vehicles. The thermostat housing plays a crucial role in regulating engine temperature by securely housing the thermostat and directing coolant flow. Constructed from durable black plastic, it features a cylindrical outlet and a flanged base with two mounting holes for secure installation.

This part is specifically compatible with Toyota models, including variants such as the Toyota Yaris 1.5. To ensure proper fitment, always confirm your vehicle's model, year, engine size, and engine code before placing an order.

A faulty thermostat housing can lead to issues such as coolant leaks, overheating, or irregular engine temperature readings. You may notice symptoms like visible coolant seepage, frequent overheating, or fluctuating temperature gauges.

It is important to replace a worn or damaged thermostat housing promptly to prevent coolant loss and maintain optimal engine operating temperature. Always inspect the housing during routine cooling system maintenance or when experiencing related symptoms.
