For vehicles with production date up to 01/1994 The E36 followed the pattern of weak cooling systems set by BMW in the late 80's. But it seems these models are excessively prone to overheating, causing huge repair bills. Due to a low coolant capacity once these engines enter the "Red Zone" on the gauge, thousands of dollars in damage is already happening.Once these models have more than 60k miles they should be serviced, then every 60k miles there after. Water pumps begin to fail, thermostats housings crack, along with expansion tanks and begin to leak due to plastic construction.This kit was put together by ECS including the basic parts that need replaced. Includes: GEBA water pump with metal impeller Fan switch Thermostat Sealing gaskets URO Expansion tank & cap 1 Gallon Coolant URO upper & lower radiator hoses URO Aluminum water pump pulley Continental Accessory belts Hose clamps
