How bad a leak? Low coolant can cause heater not to function. After radiator change, check heater hoses at firewall for hot. If 1 is cold/cool you probably have a plugged core. Backflushing may fix it. If both hot problem is inside with control system. If your truck has heater hose control valve check that too for open.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
