When your car’s heating system is defective, your comfort and driving may be impacted. Several signs indicate that your car's heating system needs to be repaired: Lack of heat Unusual odours Unusual sounds coming from fans or under the hood Incorrectly directed ventilation When your car’s heating system has a leak or a defective part, several problems can occur. If the antifreeze doesn’t have the right density, the result may be a lack of heat, which will increase fuel consumption and have a negative impact on your car's engine performance. If the thermostat stays on, you could also experience a lack of heat, and the check engine light could light up. We recommend having the heating system checked every year, and antifreeze density and condition tested seasonally.
