I want to pass on another item about the cooling lines that you may
want to consider. Many years ago when I first installed new hoses, I
also decided it might be a good idea to also change the metal lines
to SS. On my vehicle the metal lines were supported from a bracket
near the front of the engine. The bracket and the upper piece of the
clamp had been covered at the factory with some type thick woven
material I assume for insulation. When I unbolted the support bracket
to remove the metal tubes there were rather large spots of rust on
the lines where they had been clamped. I removed the rust spots that
were almost through the metal lines and discovered it was a good
thing I changed the lines as it would not have been very long until
they rusted through and probably would have squirted oil on the
nearby exhaust manifold. Apparently the fabric they used under the
clamp retained enough moisture to cause the rust.
