It's a Friday afternoon and you're parked on the shoulder of the interstate staring at an illuminated coolant temperature light on the dash of your BMW. One tradeoff of the performance provided by modern BMW models is the all-too-common water pump failures. Luckily, Mishimoto has stepped up to provide a high-quality electric water pump replacement for the BMW N52 engine! The Mishimoto N52 water pump is a direct replacement for the OEM water pump and includes replacement mounting hardware for a seamless and hassle-free installation. Because we know BMW electrical connectors like to crumble, we've also included a replacement connector and pigtail for a secure and reliable connection. To further protect your cooling system and improve water pump lubrication, refill your system with Mishimoto Liquid Chillandreg Synthetic Engine Coolant. As with all our products, this water pump is covered by the Mishimoto Lifetime Warranty.
