Upgrade your BMW's cooling system with the Mosselman Thermostat Installation Kit from Turner Motorsport, ensuring a top-quality, reliable setup for your engine.

The water pumps in BMW N54 models are known for failure near 80,000 miles. This is a very common issue that often times leaves the owner stranded. This kit provides a single stop for the water pump and thermostat replacement to save the search and get you back on the road.

Included in this kit:

Thermostat
Water pump
Genuine BMW coolant
Mounting hardware required for both the thermostat and water pump

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.

Why not upgrade when you're due for a replacement? The ECS Tuning silicone hose replacement fixes these issue with two key features in their design. Offering this hose in a much more heat resistant silicone instead of OE rubber and having the hose wrapped in aluminum. The aluminum coating acts as a heat shield to further protect the silicone as well as reducing the temperatures forced on the coolant running through the hose. 

Replaces OE hose #11537545665

Enhance the flexibility of your BMW's coolant system with the Vargas Turbo Technologies 90-Degree Coolant Tank Fitting. Ideal for applications such as single turbo setups or forward-facing intake manifolds, this fitting provides extra clearance and versatile hose routing options.

Key Benefits:

• Allows hose to run straight down, increasing clearance
• Made of durable 6061-T6 aluminum for long-lasting performance
• Anodized black finish for enhanced durability and corrosion resistance
• Includes fitting and clamp for easy installation

Upgrade your BMW's coolant system with the Vargas Turbo Technologies 90-Degree Coolant Tank Fitting for improved performance and versatility.

Upgrade your cooling system with durable silicone hoses that offer extended life and enhanced heat tolerance. Say goodbye to stock limitations and opt for silicone hoses that retain OEM fitment while overcoming typical OEM hose flaws. These hoses are designed to resist deterioration and softening due to coolant heat cycles, ensuring prolonged longevity compared to traditional rubber hoses.

Specifically, this hose connects from the thermostat housing outlet to the front of the cylinder head. Its features include:

• Inclusive of both upper and lower clamps for easy installation.
• Crafted from 4-Ply reinforced silicone, ensuring superior durability compared to OE rubber hoses that are prone to failure.
• Internal layer lined with Flourosilicone for exceptional chemical resistance.
• Silicone construction provides reduced thermal conductivity, enhanced resistance to ozone, and UV degradation, thereby boosting overall performance and longevity.
