Protect the fuel system. Don't be lured by bargain-basement gasoline prices. Change the air filter. Air filter should be changed once a year or after 12,000 miles. Maintain the cooling system.
Coolant helps cool the engine and prevents the water from freezing in the radiator.
Coolant also lubricates the engine block, radiator and bearings in the water pump. Don't wipe glass surfaces. You run the risk of scratching it. Use a wet cloth to clean glass and always use fluid when operating the wipers. Lube grease fittings regularly.
