Add strength to your cooling system and replace your water pump The secret of any reliable performance car is a rock-solid cooling system. Unfortunately, the N54's stock cooling system has several shortcomings that get in the way of reliable, repeatable, dependable performance. Turner Motorsport has spent years behind the wheel of modified N54-powered BMWs, and we've figured out what it takes to keep your N54 cool and happy. Using a combination of in-house designed parts and carefully-selected aftermarket components, we've put together an all-inclusive package that will allow you to replace your water pump and beef up your cooling system at the same time. Here's what's included: New water pump with replacement screws New thermostat Billet thermostat hose adapter (a great replacement for the stock, crack-prone plastic part!) Silicone coolant outlet hose Aluminized silicone water pump hose (aluminized for heat resistance to stay cool!) Heavy Duty aluminum coolant bleed screw (replace the strip-prone plastic screw!) New hose clamps 1 gallon of Genuine BMW coolant (just add distilled water at your desired ratio) Red Line Water Wetter (trust us, this stuff works - we've been running it for years!)Add strength to your cooling system and replace your water pump The secret of any reliable performance car is a rock-solid cooling system.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.

Kit includes

Wahler Thermostat
1 liter of Coolant

The stock thermostat is designed to open at 97C. This leaves your engine running fairly hot, and running for quite awhile before your thermostat will begin operation. With the Mishimoto Racing thermostat, the activation temperature becomes 74C. That's 23C cooler, meaning you can rest easy knowing your engine will stay cooler to help avoid all the problems that can be associated with an engine running hot. 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.
