Additionally, Zionsville Autosports' radiators
do not become weak or brittle due to constant temperature cycling.
Glass reinforced nylon will eventually deteriorate resulting in a
cracked or broken radiator neck. This failure has become more
common due to the increased temperatures in the current generation
of BMW engines. The normal operating temperature of a Double Vanos
engine is around 110° C (230° F). Unfortunately, there is no way
to tell what the real temperature is in the engine without special
equipment. According to the BMW WDS, the instrument cluster
temperature display will read normal between 75°-113° C (167°-235.4°
F). Nylon just doesn't hold up under these conditions.
