Well…
David took my bus for a thorough test drive through Bozeman pass and indeed she overheated as previously described
The fan clutch will be here Monday. They will try again to fix her up. She is starting well now but Lilly is still protesting road life in the summer heat.
I think the fan clutch might be the answer, because if the alarm goes off at 250 climbing a hill, sometimes if I throw it into neutral after I gun it up to 75 going Downhill I can catch enough fast air that the temp will drop a few degrees to turn the engine alarm off. It’s certainly not much more than if the fan was going off at the proper temp and speed to prevent the heat climbing, but it does suggest that extra air during heavy lifting will help.
Makes sense anyway.
So now I’m looking at Monday.
What an adventure you’ve had, Adeline!! I have loved watching your process, and progress all throughout. Thank you for your posts, and sharing this amazing adventure!
