Review FAE Jaguar Xjs Engine Cooling Fan Switch fits 1987–1995

The **FAE 37320** is a high-performance, precision-engineered electric cooling fan switch designed specifically for Jaguar XJS models produced between 1987 and 1995, catering to the demands of both classic car enthusiasts and performance-minded drivers seeking optimal engine cooling efficiency. This switch is meticulously crafted to replace the factory cooling fan relay, offering a robust and reliable solution that enhances the longevity and performance of the vehicle s cooling system. Built with high-quality materials, including durable brass contacts and a robust plastic housing, the FAE 37320 ensures consistent electrical conductivity while resisting corrosion and wear over extended periods of use. Its compact yet sturdy design allows for seamless integration into the vehicle s existing wiring harness, minimizing installation complexity and ensuring a clean, professional fit. The switch operates on a simple yet effective principle, utilizing a thermal or time-delay mechanism to activate the cooling fan only when the engine temperature exceeds a predetermined threshold, thereby preventing overheating while conserving electrical power when unnecessary. This not only protects the engine from thermal stress but also contributes to the overall efficiency of the vehicle s electrical system. Ideal for both stock and modified Jaguar XJS applications, the FAE 37320 is a trusted upgrade for those looking to maintain optimal cooling performance without compromising on reliability or ease of installation. Whether restoring a classic XJS to its original glory or pushing a modified engine to its limits, this switch serves as an essential component for ensuring peak cooling efficiency and engine protection.

3. **Compatibility with Modified Systems** If the vehicle has aftermarket modifications (e.g., upgraded radiators, custom cooling setups, or electronic fan controls), the stock switch may not integrate perfectly, requiring additional adjustments.

4. **Limited Longevity in Harsh Conditions** Extreme heat, moisture, or electrical interference (e.g., from other faulty components) can still affect the switch s lifespan, though it should last significantly longer than a failing original.

5. **No Warranty on Some Retailers** Some online sellers offer no return or warranty policies, leaving buyers without recourse if the part fails shortly after purchase.
