Our Stage 2 E36 3 Series Cooling System Overhaul Kit includes all the common preventative maintenance parts to keep your cooling system from failing at an inconvenient time, including some recommended upgrades to add peace of mind. This overhaul service typically needs to be performed at 80-100,000 miles due to plastic fatigue on the radiator tanks and thermostat housing.

Stage 2 Kit Includes:

  • CSF OE Plus Radiator; drop-in fit that functions as well or better than your existing radiator with newer technology, a higher-performance core, and B-Tube technology
  • Stewart Components/EMP performance water pump - now with a lifetime warranty! This is a premium water pump packed with features like improved vein design for better flow, an oversized bearing, and the best seals available. 
  • Silicone radiator hose kit for added durability to the cooling system
  • Aluminum thermostat housing - upgrade from factory plastic
  • Thermostat housing gasket
  • Thermostat - 88 degree
  • Radiator/expansion tank cap
  • Accessory belt

This kit fits 6-cylinder E36 3-Series cars (323, 325, 328, and M3). Kit will not fit the Z3/MZ3.
