Hard to find coolant leak

[dougimes]

I have a hard to find coolant leak, losing a gallon every 50 miles.

my observations.

only happens while operating.
only visible liquid is down wind (while driving) of the overflow tube. coating the right axle and leaf springs. no other trace above that.

system holds pressure. After you stop, a few hours later I still have pressure in the coolant system.


oil looks normal. not foamy, or brown.


anyone seen anything like this?

Does your radiator need to be rodded out?

Possibly that, and check the radiator cap for correct pressure. (and type). ours did that untill we changed it.
Same on the deuce actually.

I replaced the radiator cap with new, 13psi type.

Not sure what the correct pressure should be. that is the one that came up for the Gladiator.

let you know if it fixes it.
