Cord uses 1", 1 1\8", 1 1\2" & 2" I.D. straight hoses which you can order from Rock Auto and cut to length. Only the upper rad hoses are easy to change. The hoses between the blower and the thermostat housings aren't hard either but do take some time. The remaining hoses require the water pump to be removed which required most of a day and ample patience.
