Under the hood of your Toyota, there's a couple of key parts that keep everything working properly. A timing belt is a notched rubber belt that allows the crankshaft to turn the camshaft. Drive belts (AKA serpentine belts), provide power to the air conditioning, power steering, cooling fan, and more. You should get both belts inspected during oil changes, as if they stop working it could cause major engine damage. You can check the belts for fraying or signs of wear and tear. You also might hear loud sqealing noises if they are wearing out. Coolant hoses provide for coolant flow between the engine, radiation, and heating blocks. Get your hoses inspected twice a year.
