Update - Thermostat and radiator service, with 6,000 pound in tow.

[Terry Neal]

Evening Curt,

My guess is the correlation for much of the cooling system repairs on
these Detroits would be best expressed in terms of years rather than
miles. Most automotive heating/cooling hoses have a "safe" life around
maybe 5-7 years in my opinion. These are all original hoses etc that I
am replacing so feel am pushing my luck in running them any longer on
the coach. The rad core was shot, maybe it would have lasted another
5,000 miles but I seriously doubt it.

I pulled the turbo & blower off for better access to all the other
parts. Figured I might as well rebuild them & replace all the bearings
while at it. Also had a gasket failure at the blower mounting flange.

I do have a history for all the work on the coach & it was pretty
complete when I purchased it.

The coach is parked at my Land Rover shop in Billings. Plugged into
240-50 amp service & water & sewer hookups. I have done some of the
work on it myself but also have employees that work on it when time permits.

It's also getting stripped and is about ready for repaint when it warms
up some.

Plan to be able to use it quite a lot when it's all finished.

Mexico is calling...The report is that they have some beer & tequila
left down there.
