BMW E46 323/328 Cooling System Refresh Kits

The engine in the E46 is known for only one weakness - the cooling system.

The ultimate assurance that you wont be left on the side of the road with an over heated engine is to refresh all the major components at the first sign of any failure.

In many cases, E46 engines last the life of the vehicle - meaning by this time there will be more wear and tear on cooling system components than predicted by BMW.

ECS offers Cooling System Refresh Kits with varying levels of components for this very reason - Three stages of ECS-assembled and Genuine BMW kits are available.
