BMW Cooling Overhaul Kits

The water pump is a known weak point across all BMW models, requiring servicing every 60,000 miles. Along with the water pump, it’s wise to replace the thermostat to ensure your cooling system operates at peak efficiency.

This kit features a 90°C (194°F) thermostat from Hamburg Technic, which opens approximately 15°C earlier than the standard factory thermostat. This lower temperature is particularly advantageous for performance-focused applications.

What's Included:

Genuine BMW Mechanical Water Pump Assembly (11517846361) Hamburg Technic Performance Thermostat - 90°C/194°F (11537586885) Genuine BMW Coolant/Antifreeze - Diluted, 1 Gallon (82141467704) Benefits of a Lower Thermostat Temperature:

Enhanced Engine Cooling: Opens sooner to reduce engine temperature more effectively. Improved Performance: Keeps engine components cooler, allowing for better performance in high-stress conditions. Extended Engine Life: Reduces thermal stress on engine parts, promoting longevity. Prevents Overheating: Helps to avoid overheating in demanding driving scenarios. Optimized Fuel Efficiency: Maintains ideal engine temperature for efficient fuel combustion. Elevate your BMW's cooling system and performance with this expertly curated kit from Turner Motorsport.

The water pumps in these BMW models are known for failure near 80,000 miles is a very common issue often times leaving the owner stranded. This kit provides a single stop for water pump and thermostat replacement needs to save the search and get you back on the road.

Kit includes:

• Genuine BMW Thermostat
• OEM Pierburg Electric Water Pump
• Genuine BMW Antifreeze/Coolant
• OEM Mounting hardware required for both the thermostat and water pump

Looking to improve your cooling system's performance and add some peace of mind at the same time? Look no further. This kit includes everything you need to add performance, durability and longevity to your cooling system without spending a ton of money. Best of all, the upgrade can be performed by a reasonably competent DIY enthusiast in an afternoon. The team at ECS Tuning supplies their excellent silicone radiator hoses, stainless hose clamps, and aluminum coolant bleed screw for increased durability and heat resistance. Meanwhile, a lower pressure expansion tank cap makes for a less costly "weak link" if the system builds too much pressure, potentially saving you from a costly radiator replacement that could leave you stranded. The kit also includes a gallon of Genuine BMW coolant along with 12 ounces of Red Line Water Wetter, which lowers operating temperatures and protects your cooling system from internal corrosion. All you need is this kit, a few hours of free time, and a gallon of distilled water to keep your E36 cool & running at its best!

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.
