Coolant, also known as antifreeze, is crucial for maintaining the engine's temperature within optimal limits. It circulates through the engine and radiator, absorbing heat and preventing the engine from overheating.

Identifying the Source of the Leak

• Inspection Tips: Look for cracks or damage on the radiator body and hoses.

2. Water Pump

• Signs of a Leak: Wetness or a drip around the water pump.
• Inspection Tips: Check the seal and the condition of the water pump. A weep hole leak or seal degradation can cause leaks.

3. Hoses and Clamps

• Signs of a Leak: Cracks or splits in the hoses, loose or corroded clamps.
• Inspection Tips: Squeeze the hoses to check for brittleness and look for any signs of wear or damage.

4. Heater Core

• Signs of a Leak: Fogging inside the car, a sweet smell, and wetness inside the passenger compartment.
• Inspection Tips: Inspect the heater core which is typically located inside the dashboard.
