Audi A4 Quattro Engine Coolant Hose Flange Kits

Rein Upgraded Aluminum coolant flange replacement kits are built with direct-fit, premium components to provide a complete and convenient solution for a typically time-consuming repair. These kits address all critical parts involved in replacing cracked, leaking, swollen, or deteriorated cylinder head coolant junction flanges-including the flange itself, thermostat, temperature sensor, heater and/or radiator hose(s), and all required gaskets and seals. Plastic flanges often fail due to repeated thermal cycling, leading to warping and coolant leaks. Rein upgrades the flange to durable aluminum for extended service life, while the replacement hose(s) feature premium rubber compounds and factory-style quick-connect fittings for secure, reliable installation.To ensure lasting results, Rein recommends replacing all compromised cooling components and performing a full coolant flush using high-quality coolants such as Pentosin Pentofrost. Rein kits offer a Fix-It-Right-The-First-Time solution to restore long-term cooling system performance.

Rein OE Quality coolant flange replacement kits are made up of direct-fitting premium material components. They focus on all of the parts surrounding the replacement of the cracking, leaking, swelling or deteriorating cylinder head coolant junction flange, including 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 deformation and coolant leaking. The included replacement coolant flange is made out of virgin OE-type resin for added durability, and the included replacement hose(s) are made out of OE-type rubber compound with OE-type quick-connect hose end fittings. Replacing leaking and failing cooling system components and performing a proper coolant flush at the same time will ensure a long life of the vehicle’s cooling system. Rein recommends OE or Pentosin Pentofrost series coolants for this job. Rein coolant flange replacement kits offer a convenient Fix-It-Right-The-First-Time solution for this common but time consuming repair!
