Engine & Tranny problems 2

[Gregory OConnor]

I wonder if humid air is a better heat sink then cool air?? Here in
California it is a common maintenance practice to pull and rod a
radiator. The Radiator size and dynamics are set up to maintain a
given range of temp. Too big a radiator, too cool a running temp is
also not desired. If your rad is blocked in core or compramized on
surface 20 or 30% I would think it could prove the 10% heat issue you
have.???? I think pulling the radiator for rodding and inspection
would never be a $waste even if it does not prove to be the cause of
your heat issue
