BMW Cooling System Parts & Accessories for BMW E36 (1992-1998) M3

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.

The fan that attaches to the water pump carries so much rotational mass that it can actually hinder the performance of your engine. To address this, we now offer out line of fan delete kits that replace everything needed to get rid of your fan and fan clutch, without causing cooling issues as a result. This Comprehensive kit is the mid-priced option, including the essentials and an upgraded aluminum thermostat housing that won't crack or break like the brittle plastic housing. 

This kit is best for someone who wants to upgrade their thermostat housing to aluminum, has already upgraded their water pump pulley, and has performed regular maintenance on their engine drive belts.

Included in this kit:

• 80* thermostat
• 1 liter of coolant
• Water Wetter coolant additive
• Low-temperature coolant temperature sensor/switch
• Aluminum thermostat housing with gaskets
• Fan delete nut

Fits the following BMWs:

Looking to improve your cooling system's performance and add some peace of mind at the same time? Look no further. This kit includes everything you need to add performance, durability and longevity to your cooling system without spending a ton of money. Best of all, the upgrade can be performed by a reasonably competent DIY enthusiast in an afternoon. The team at ECS Tuning supplies their excellent silicone radiator hoses, stainless hose clamps, and aluminum coolant bleed screw for increased durability and heat resistance. Meanwhile, a lower pressure expansion tank cap makes for a less costly "weak link" if the system builds too much pressure, potentially saving you from a costly radiator replacement that could leave you stranded. The kit also includes a gallon of Genuine BMW coolant along with 12 ounces of Red Line Water Wetter, which lowers operating temperatures and protects your cooling system from internal corrosion. All you need is this kit, a few hours of free time, and a gallon of distilled water to keep your E36 cool & running at its best!
