Audi VW Cooling Fan Switch - Rein 1J0959481A

Product Information

An Engine Cooling Fan Switch monitors the engine temperature and controls the operation of the cooling fan, which helps regulate the engine's temperature by drawing air through the radiator. When the engine reaches a specific temperature, the switch activates the cooling fan to help dissipate heat and prevent overheating.

• Overheating Engine: A malfunctioning cooling fan switch may fail to activate the cooling fan, causing the engine to overheat. If the fan doesn’t turn on when needed, the engine temperature can rise dangerously high, potentially leading to serious engine damage
• Constantly Running Cooling Fan: If the switch is stuck in the "on" position, the cooling fan may run continuously, even when the engine is cool. This can lead to unnecessary battery drain and increased wear on the fan motor

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
