Cooling System Refresh Kit - Level 2 - E60 E61 N54
This cooling overhaul will cover just about everything you could replace on the 535's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N54 engine. But to properly maintain these cars for the long term, the rest of the cooling system must be refreshed and preventatively replaced. Here you can add a radiator, expansion tank, 535 cooling hoses, and the BMW antifreeze
