How do you bypass the heater core on a 1988 Ford Bronco II?

Answer 1

I actually had to do that on an old Cherokee I once owned because the core was leaking and I didn't have the money to fix it. I just disconnected the hoses from the heater core and coupled them together, end to end, with some hardware and hose clamps. Those hoses are usually different sizes, so you might have to fiddle around a little. Measure the inside diameter of the hoses, then run down to the local hardware or home supply store and find the little pieces parts that you need to make it work. FriPilot

I also once did this, although on a 1979 F100. In a real rush, try a 5/8" deep socket. I think heater hose size is pretty standard on Fords, 5/8" ID. I don't recommend this except in an emergency, as you don't just lose heat (get closer baby!! yeah that's it!!), you also lose your defroster. Makes for interesting driving. I swear I never saw the cop that popped me for speeding despite the fact he was just parked by the roadside, but I couldn't tell him my excuse!
