Historically, BMW vehicles have been plagued with rather frequent cooling system failures. A majority of these failures are a result of the use of plastic components in a high-temperature application. Although failure isn’t immediate, over time the frequent heat cycling of these plastic components results in increased fragility, fatigue, and eventual failure.
A few components we see failing on E36 models include the radiator end tanks, radiator expansion tank, and the mechanical fan. We already offer two aluminum radiator options, and we have an electric-fan conversion kit in the works. An expansion tank is our last stop for product development on the E36 (for n
