Cooling System Service Kits | Audi B5 A4 1.8T

A critical maintenance need in your Audi is refreshing the Cooling System.

The components and coolant are subjected to extreme temperatures and drastic fluctuations between hot and cold under even normal driving conditions. Excessive heat from competitive conditions exponentially increase the stress on your system. This causes deterioration of hoses and housings, which inevitably lead to coolant leaks and improper cooling of your engine.

Regular replacement of system components and flushing your coolant are important to ensure proper function.
