Radiator Rebuilt For Our 84FC

[Eric Johnson]

Hi Ed,
We also had a great time at the Spring Texas rally and hope we'll see you folks
again in
April. Seems to me that having some Louisiana Birds at the Lone Star rallies
sure adds a
lot of life to the party!

On the subject of the radiator, the shop advised me not to get a new core since
they
found less than 10% plugged tubes. They rodded it out and repaired a couple of
small
leaks on the top tank seams. I put it back in and ran down to I-10 to fill up
at the Flying J.
The coach jacket water temperature is running measurably cooler, slightly under
180
degrees, at 60-65 mph.

Looks like I cured the small hose leaks we noticed at the rally. Combination of
double
clamping those joints with the copper tubing and used gasket shellac with a
single clamp
on the pipe joints close to the block. Carefully positioned the clamps so they
can be
tightened up from below.
