Mishimoto MMRT-E36-92E - Aluminum Expansion Tank for E36 — Overview

This is a direct-fit aluminum expansion tank for the E36 cooling system, meant to replace the stock plastic tank that gets brittle with age and heat cycles. It fits 1992-1999 BMW E36 3 Series applications and makes sense if you are refreshing a higher-mileage car or trying to get ahead of the usual cooling system failures. On these cars, the weak point is often not if the plastic lets go, but when.

I would pick this over another OEM-style plastic replacement if the car sees track days, hot climates, or you just do not want to revisit the same job again. If you are keeping a lightly driven street car completely stock, plastic can still be fine, but aluminum is the better long-term answer here. Just make sure the rest of the cooling system is up to the same standard, because an upgraded tank will not save an old radiator hose or tired thermostat housing.
