Any GURUS have experience retrofitting a classic with an overflow tank? I don't have one on the 1984 and can only assume that it didn't come with it, or it wasn't replaced during the engine overhaul. As a result, the coach runs a low coolant level an inch or so below the sight glass window. The only way to check the level is to remove the cap before starting out and inserting a piece of paper towel in the tank, and looking for liquid on the paper towel when pulled out. If I replace the missing coolant, it will be an inch below the sight glass when cool the next morning.

Also, we came thru the Palm Springs area in 95 degree weather last week, pulling a fairly light enclosed trailer (2500lbs) On a moderate grade the old analog temp gauge went up to 190 as did the electronic Digipanel. I slowed down to  45 and dropped down a gear with rpm's at 1800. After a few miles, the temp went to the green on the Digipanel  at 180 degrees, confirmed by the analog gauge. I was wondering if the close proximity of the trailer being towed, 5 ft, was inhibiting the radiator fan from blowing out the heat?
