1. Warning lights and indicators – No one likes to see the engine light illuminate on the dashboard, but when one of the warning lights comes on and stays on while driving, check your owner manual and follow its advice. Waiting to do repairs can be costly and even dangerous.
2. Oil – Engine oil not only lubricates and cools internal engine parts, it collects and traps dirt, as well as contaminates from the combustion process. That is why you should have it changed regularly.
3. Air filter – Don’t let your vehicle’s air filter get too dirty. A clogged filter restricts airflow, robbing horsepower and potentially fuel economy. If you’re unsure about when to change the filter, have your ACDelco affiliated technician check it out.
4. Heater/Defroster – The heater/defroster in your vehicle draws its heat from the circulation of hot engine coolant. If you smell a sweet, syrupy odor inside the vehicle or spot a greasy mist on the inside of the window, there may be a leak in the heater core. Have it checked out.
5. Tire pressure – Under-inflated tires waste gas and can prematurely wear out the tires, because they generate more friction on the road. Making sure your tires are properly inflated is one of the easiest things you can do to optimize fuel economy and tire longevity.
