The cooling system on the XR4Ti is fairly unique. If there is
another car with more individual hoses in the cooling system,
we have yet to see it. Compound this with the changes
throughout the model run and it gets even more complex. We
have a good inventory of the hoses and other cooling related
components that fit 1985-87 XR4Ti and some (where similar
or noted) for 88-1989 cars.

Cooling System (Scorpio)
In addition to our stock of cooling system components for the XR4Ti
we have added the various Scorpio related items to our inventory.
The Scorpio's cooling system is only slightly less complicated than
the XR4Ti's, it's only saving grace is the parts do not vary all that
much from year to year. Again, as with the XR4, components that
we offer are from the O.E. supplier or Ford originals.

pE Radiator- new original equipment Ford radiators at a very
attractive prices. Don't be mislead into buying substandard
fabricated or fits-all radiators when we can supply new Ford ones
for less.
