Bleeding heater during install?
We're getting ready to put our driver-side heater back in (the only heater in the bus). I was wondering if there's anything special that can/should be done to get all the air out. There are two points of concern for me: The heater itself, and the high point in the lines running to it.
1) The heater: Should I bench bleed / prefill this before installing it? Put it in dry? Does it matter?
2) The hoses: The hoses make a pretty steep ascent up to the point where they enter through the firewall, then from there a mild descent to the point where they connect to the valves in the engine compartment. So there's a high-point in these heater hoses at the exact point where they enter through the firewall. Is this anything I need to concern myself with? It's not the high-point in the system, obviously (the coolant reservoir / degas tank is). But it is a peak in the hoses themselves.
Thanks. Probably stupid questions, but the last stupid question I asked without waiting for an answer on bit me. Any help would be very much appreciated.
