I ran into a problem adapting radiator hoses for a "built" 250 in an early roundbody. I needed a bigger X-Flow radiator - so I used hoses from a 77 Granada 250 which had a X-Flow OEM. I ran into a problem with the lower hose. it was molded for the 250 Pump inlet but the radiator outlet side was too small (1-1/4?) for the 1-3/4 Aluminum aftermarket X-flow radiator. After wrestling and lubing it to no solution - I wound up using an Exhaust pipe stretcher - that expands the pipe. After putting the expander in the hose and using the air wrench on the expander , it was easily installed on the oversize radiator outlet.


I just figgered' someone might remember and use this ...

I would keep an eye on the stretched end and inspect it regularly. If any of the entrained reinforcement fibers broke in the hose while stretching it, the service life of the hose may have been reduced.

Good observation. I was surprised that the expander actually could not force any more ID at a point without much more effort. Continuing would probably cause the fault condition you caution against.
