Replacement of the heater core on a 1993 Mazda Protege is going to first require the removal of the entire dashboard. Once that is removed then the heater control box will need to be removed and disassembled in order to get access to the heater core inside.

In dash. Look for 2 hoses on firewall-it's behind them. Replacement is not a job for a novice.

Not necessarily. It depends on what you mean by a bad heater core. The core will either be leaking or stopped up. If it is leaking, then it can cause the engine to overheat and the only fix is to replace it. A clogged or plugged heater core can sometimes be fixed by flushing it. You can also temporarily bypass the heater core until you can get it fixed. Just connect the inlet & outlet heater hoses together.

To bypass the heater core you need to remove the two water hoses going through the firewall from the engine compartment to the heater core and connect them together so that the water loops around back to the engine.

Yes, you can bypass the core. Find the hoses to the heater core. Remove them from the core ... as a worst case scenario, cut them. Install a double male hose connector with clamps on the hose ends to complete the bypass fix. . mm
