Why Your Heater Core Might Need Replacing

Before diving into the replacement process, it’s essential to understand the signs that indicate your heater core needs attention. Here are some common symptoms:

• Sweet smell inside the car: A sweet, almost syrupy smell coming from the vents is a telltale sign of coolant leaking from the heater core.
• Foggy windshield: If you notice your windshield fogging up even when the defroster is on, it could be due to coolant leaking onto the windshield.
• Low coolant levels: A leaking heater core can lead to a gradual decrease in coolant levels in your car’s reservoir.

Gathering Your Tools and Supplies

Replacing the heater core in a 2000 Lincoln Town Car is a significant undertaking, requiring a specific set of tools and materials. Gather the following before you begin:

• A complete set of metric wrenches and sockets: You’ll need a variety of sizes to loosen and tighten bolts and nuts.
