BMW's cooling system has long been a known weak spot, with the water pump and thermostat being two of the most common trouble areas. This remains true even in the latest B-Series engines found in 2016 and newer BMW models. This kit includes a brand-new OEM Pierburg water pump, a Bremmen thermostat (now referred to as a Heat Management Module), and one gallon of BMW's G48 coolant concentrate (enough to make two gallons of 50/50 coolant). Avoid spending thousands at the dealership or over $600 on Genuine BMW parts! These components can be replaced with high-quality OEM parts in just an afternoon using basic hand tools.

It is important that your coolant system is serviced at regular intervals to ensure a long life. Over time, coolant systems are exposed to high temperatures and repeated thermal cycling, which causes warping, cracking, and hardening of plastics and rubber components in the coolant system. This can lead to coolant leaks and overheating, which can result in extensive engine damage if not resolved in a timely manner. This Water Pump & Thermostat kit helps to address a few of the most problematic parts, replacing these items entirely to keep your cooling system running optimally and efficiently.

When it comes to your temperature gauge on your instrument cluster your thermostat plays a large role in where that temperature needle ends up. There are many cases where the vehicle will run a bit cool according to that gauge, oftentimes meaning the thermostat has failed and is stuck open allowing coolant to continuously circulate. The other more damaging side is when it closes shut and keeps the engine from cooling down properly. All vehicles are designed to operate in an ideal temperature range for the ultimate efficiency, life, and performance.
