Car Overheating Due to Heater Core Leakage: Symptoms and Solution
Is your car overheating? Are you noticing temperature gauge spikes, especially during winter months when you're using the heater? A heater core leakage might be the culprit.
*Symptoms of Heater Core Leakage:*
1. Overheating engine
2. Temperature gauge fluctuations
3. Coolant leaks under the dashboard or on the passenger floor
4. Foggy or misty windshield
5. Reduced heater performance
6. Sweet, syrupy smell inside the car (coolant odor)
7. Green or yellow fluid dripping from the heater core
*Causes of Heater Core Leakage:*
1. Corrosion or rust
2. Age and wear
3. Clogged or blocked heater core
4. Poor coolant maintenance
*Solution:*
1. Inspect and replace the heater core if damaged
2. Repair or replace hoses and connections
3. Flush and refill coolant system
4. Use a rust-inhibiting coolant (never tap water)
5. Check and replace thermostat if necessary
*Why Never Use Tap Water:*
1. Tap water contains minerals that promote rust and corrosion
2. Rust can damage engine components, radiator, and heater core
3. Tap water can cause coolant system failure
*Benefits of Using Coolant:*
1. Prevents rust and corrosion
2. Maintains optimal engine temperature
3. Ensures efficient heater performance
4. Protects engine components and radiator
*Best Practices:*
1. Check coolant level regularly
2. Use a 50/50 coolant-to-water ratio
3. Change coolant every 30,000-50,000 miles
4. Inspect heater core and hoses annually
