6 inline. I replaced the tank and bled it multiple times on a current battery maintainer of 50 amps 14.4v
Not the first time bleeding, I have been with bmws for a while so I’m just a little confused whethe the thermostat opens only at high fan 84’ water pump works, fan works at variable speeds even when gassing it (with full heat on) agh I just wish ista would start working on my laptop. Hopefully I can see some figures … maybe sensors ,,,
