Description Reviews As our beloved R56 MINIs get older, they’ll need a little more love and maintenance to keep up with the pack. Over years of tinkering under the hood, one piece that doesn’t seem to stand the test of time is the OEM coolant T-Fitting. This T-Fitting is a very important three-way intersection that connects the Turbocharger and the Thermostat Housing to the coolant expansion tank. Typically breaking this T-Fitting means replacing the entire coolant line, but we’ve isolated the weak link so you can simply swap out the cheap plastic T-Fitting for a much more durable, black anodized aluminum version that will allow you to keep the rest of your coolant hose system intact. If you need they whole line, we recommend this one! Instruction link
