Coolant Thermostat Housing 25192230 for Vauxhall Opel 1.6 1.8 FAQs

How do I ensure this part is compatible with my specific vehicle?

This thermostat housing is designed for Vauxhall and Opel models, specifically the Astra H/J, Insignia, and Zafira equipped with 1.6L or 1.8L petrol engines (Engine codes like A16XER or B16XER). It replaces multiple OE numbers, including 25192230, 55564890, and 1338256. To avoid compatibility disputes and ensure a leak-free fit, we strongly recommend cross-referencing your original part number or checking your vehicle’s VIN before ordering. While this is a high-quality aftermarket component built to OEM specifications, verifying the physical appearance against your current unit is the best way to confirm a perfect match.

What are the signs that I need to replace my thermostat housing?

You should replace your thermostat assembly if you experience engine overheating, a "Check Engine" light related to cooling, or if the engine takes an unusually long time to reach operating temperature. Our assembly solves these issues using a high-quality wax element that opens at precise temperatures to maintain the ideal thermal range. This prevents engine "sludge" and reduces emissions. Replacing a cracked or sticking unit with our stainless steel reinforced housing prevents catastrophic coolant loss, protecting your engine from expensive internal damage while significantly improving overall fuel efficiency and performance.

What are the installation requirements and safety precautions?

For your safety and to maintain warranty eligibility, this part must be installed by a certified professional mechanic. Cooling systems are pressurized and can cause severe burns; never attempt to open or replace the housing while the engine is hot. Please ensure the mounting surface is clean and the included corrosion-resistant gasket is seated correctly to prevent leaks. Note that we are not liable for labor costs or engine damage resulting from improper DIY installation. This product is intended strictly for the specified vehicle applications; use in modified or unintended engines voids all guarantees.

What makes this product reliable, and what does the warranty cover?

Our thermostat housing is built for longevity, featuring a stainless steel main body and valve paired with a specialized rubber seal that resists chemical corrosion and extreme thermal cycling. Unlike standard units, it is designed to perform in the harshest engine bay conditions. We offer an unmatched 7-year warranty against manufacturing defects and a 365-day satisfaction guarantee. If the product fails to meet performance standards within these timeframes, our after-sales team will provide a replacement or resolution. This commitment ensures your vehicle remains reliable for years to come, reducing the frequency of repairs.
