Radiator Expansion Tank Cap For BMW E36 E46 E39 X3 E83 X5 Z4 (USA Only)

Descriptions:

Catastrophic cooling system failures are a fairly common problem for BMW vehicles. It is related to the cooling system maximum relief pressure that they had chosen to run, coupled with an almost entirely plastic set of cooling system components. The problem is that these plastic parts heat cycle hundreds of times while exposed to the degrading effects of heat and coolant, they lose some of their strength. The result can be a ruptured part somewhere in the cooling system. Especially for BMW vehicles manufactured between 1982 and 2006.

Features:

【Maintenance upgrade】If your vehicles is more than 5 years old, it's a good idea to replace the cooling system cover in order to maintain the cooling system.
