85c Thermostat | BMW M60

My water pump started seeping coolant out of the shaft, and I already stress way too much about my e30 overheating with an M60 in it. So much so that I've installed extra gauges and additional ducting to try and help it out/keep track. While not actually overheating (often), I wanted to go a step further.

This upgrade isn't new - the forums discuss it a ton, and I'm sure there are a few videos out there too. Being that my M60 is installed in an E30, maybe this take could be more helpful to you.
