Thermostat Housing Kit – M30

Product Description Is your old thermostat housing corroded and your thermostat no longer working? This is a replacement thermostat housing kit that replaces all of your faulty parts. This is the later style housing and thermostat (post ’85). Installation Note: Upon installation/cooling system overhaul, be sure to bleed the coolant system. Many people (and shops unfamiliar with BMW’s) will skip this step, resulting in sustained high temperatures and a bubbling sound. To bleed the system, back out the bleeder screw on top of housing to let the trapped air out. Once coolant begins to come out, re-tighten the bleeder screw. Installation is as per your workshop manual.
