Audi B6 A4 1.8T Cooling Flange
The cooling flange, located on the rear of the cylinder head, lives in a tough neighborhood where it is exposed to very high temperatures and repeated thermal cycling. Heat-hardening causes housing warpage and cracking that leads to coolant loss and possible engine damage from overheating.
With summer heat upon us, this is a great time to give your cooling system a thorough overall inspection.
ECS Tuning stocks parts and factory-approved coolant formulas to protect your cooling system and keep you motoring.
