Material Matters: Aluminium vs. Plastic
In the realm of thermostat housings, the material selection plays a pivotal role in the component’s performance and longevity. Plastic thermostat housings, while initially economical, are notorious for their susceptibility to high temperatures and pressure, which can lead to warping and cracking over time. This degradation compromises the housing’s integrity and poses significant risks to the engine’s cooling system.
On the other hand, aluminium thermostat housings present a robust alternative. Known for their superior strength and thermal conductivity, aluminium housings can endure higher operational temperatures without losing structural integrity. Unlike plastic, aluminium does not degrade as quickly, offering a more resilient solution that matches the rigours of high-performance engines.
Thermal Expansion and Contraction
The aluminium’s resistance to thermal expansion and contraction further enhances its reliability, ensuring a consistent seal that prevents leaks. This reliability is particularly beneficial in performance-oriented vehicles like the BMW E46, where maintaining precise engine temperatures is crucial.
The transition from plastic to aluminium represents not just an upgrade in material but a significant improvement in the overall performance and dependability of the vehicle’s cooling system.

The material’s thermal conductivity also efficiently manages engine heat, contributing to a stable operating temperature. Furthermore, aluminium thermostat housings are long-lasting, requiring fewer replacements over the vehicle’s lifespan.
Long-Term Cost Savings
This durability translates to long-term cost savings, as the frequency of repairs and replacements is significantly reduced. For E46 owners looking to maintain their vehicle’s performance and reliability, the benefits of switching to an aluminium thermostat housing are clear and compelling.
Installation Process
Replacing the thermostat housing on a BMW E46 requires careful preparation and the right tools. Begin by ensuring the engine is completely cool to avoid any risk of burns or other injuries. Disconnect the battery to eliminate any chance of electrical shorts during the procedure.
Using a socket set and screwdrivers, remove any components obstructing access to the thermostat housing, such as hoses or sensors. Carefully detach the existing plastic housing, taking note of the positioning and alignment for reference during reinstallation.
Once the old housing is removed, clean the mounting surface thoroughly to ensure a proper seal for the new aluminium housing. Position the new aluminium housing and secure it using the bolts removed earlier, tightening them to the manufacturer specified torque settings with a torque wrench.
Reattach any removed hoses or sensors, ensuring all connections are secure to prevent leaks. Reconnect the battery, refill the coolant if necessary, and start the engine to check for leaks or irregularities. This methodical approach ensures a successful installation, providing enhanced reliability and performance for the vehicle.
