So I’ve been chasing a cooling issue on my 2008 we 135i. I originally thought it was the water pump because when I did the bmw water pump test there was no stream coming from the reservoir. I switched the water pump out, still nothing, then I switched out my thermostat and still nothing, and most recently I switched out the buss fuse In the power distribution box on top of the battery because that had been the reason on my old 335i but still not working, I’ve got no idea what to do next and any thoughts or advice would be greatly appreciated.
