The new OE-quality REIN Coolant Flange Replacement Kit (Part No. CHS0648)--brought to you by CRP Automotive--focuses on all of the parts surrounding the replacement of the cracking, leaking, swelling, or deteriorating cylinder head coolant junction flange. These kits include the flange, thermostat, temperature sensor, heater and or radiator hose(s), and associated gasket(s) and/or seal(s). Repeated thermal cycling of the plastic coolant flange leads to its deterioration and coolant leaking. The included REIN replacement coolant flange is made out of OE virgin resin for added durability, and the included replacement hose is made out of OE compound EPDM material with OE-type quick-connect hose end fittings. When replacing leaking and failing cooling system components, it is important to perform a proper coolant flush (using OE or Pentosin Pentofrost series coolant) at the same time to ensure a long life of the vehicle's cooling system. REIN Coolant Flange Replacement Kits offer a convenient Fix-It-Right-The-First-Time solution for this common but time-consuming repair!
