Cruisers usually have a heavy-duty oil-to-water oil cooler, it feeds coolant from the radiator thru a block-mounted oil cooler. If you have this cooler (and some of the newer Bronc's DO as evidenced by the recent thread on exactly that subject) then you might be able to use the Police Package hoses. Remember though that the Crown Vic doesn't necessarliy mount the engine & radiator exactly the same as a Bronco so the hoses may not be long enough for the application. If you're friendly with a junkyard or know someone with a Hollanders interchange manual they can look it up for you or you could check with a dealer & see if the Bronco hose shares a part number with a tow-package equiped Crown Vic because those should both have the HD cooler, if the numbers match then the cruiser hoses should work.
Either that or someone here who knows for sure will pipe up & tell us <grin>
