RE: Radiator Cap

["Farmer" <pharmer@domain.elided>]

George,

I can't help you with the IH specifics.  However, I can tell you that my '74
travelall was running with a 7lb cap, which I replaced with a 13,14,or 15lb
cap (can't remember which).  This was on advice of some cooling specialists
who said that I needed a higher cap for higher altitudes (I'm at 7k feet).
Well, that's true - but it ignores the fact that the cooling system wasn't
up to it!  My radiator promptly died the death of a thousand leaks.  Of
course, now that I've got a new radiator core, and a 14 (?) lb cap, it cools
really well! ;-)

So if your radiator is in good shape, then I'd think you could go to 12 lbs
at sealevel & 14 at altitude.  I'm sure somebody will fine-tune these
numbers.  Otherwise, if your radiator is kinda bad, and you aren't towing in
the heat, you might coax a few more years out of it by keeping that 7lb cap
on.
