PFA Reproduction DB5 and Early DB6 Thermostat Housing

New Aston Martin DB5 & Early DB6 Thermostat Housing

We’re excited to announce the availability of a newly reproduced thermostat housing for Aston Martin DB5 and early DB6 models. After decades of service, original units often have severe corrosion. This leads to compromised threads and sealing faces, and ultimately, coolant leaks. Our high-quality replacement ensures your classic Aston Martin’s cooling system performs reliably.

Addressing Common Classic Parts Issues

Original DB5 and early DB6 thermostat housings are now about 60 years old. Over time, exposure to coolant and heat causes significant corrosion. This makes them highly susceptible to failure. It typically manifests as stripped threads for the temperature sensor or uneven sealing surfaces. These issues lead to frustrating and potentially damaging coolant loss. Our new production solves these common problems. It offers a fresh, robust component that’s ready to install.

Enhanced Design for Superior Reliability

We meticulously crafted our thermostat housing to replicate the original. But we also added a subtle yet significant improvement. We incorporated an extra 2mm of material to the height of the temperature capillary boss. This thoughtful enhancement provides greater thread engagement for the temperature sender. It improves its security. It also reduces the likelihood of future issues from vibration or thermal expansion. This ensures a more reliable and leak-free connection for your DB5 or DB6’s temperature gauge.

Precision Manufacturing with New Tooling

We manufactured these Aston Martin thermostat housings using brand new tooling as of January 2025. This ensures exceptional precision, consistent quality, and an exact fit. Our commitment to using modern manufacturing techniques, while respecting the original design, means you receive a part that meets the highest standards for your vintage vehicle.
