  1. No problem at all to do, was quite common in the old days. Disconnect one hose from the heater core, at the heater core. Disconnect the other heater core hose from the engine and loop the first hose around and connect it at the engine. You have just bypassed the heater core. Top off coolant level and your good to go.
