Replacing these coolant lines or at least checking them is really a
good idea. On my 82 PT 40 I got to do this on the side of the road.
This is no fun and usually a nasty dirty job. these coolant lines
provide the coolant for the engine air compressor and a leak can
cause significant engine coolant loss resulting in engine overheating
in a very short time so all who have suggested checking them are
right. In addition to engine overheating even if you catch the leak
in time it still makes a hell of a mess on the bus and tow vehicle.

This is no fun and usually a nasty dirty job. these coolant lines
provide the coolant for the engine air compressor and a leak can
cause significant engine coolant loss resulting in engine overheating
in a very short time so all who have suggested checking them are
right. In addition to engine overheating even if you catch the leak
in time it still makes a hell of a mess on the bus and tow vehicle.
