Mechanic taking apart of an engine out from under the hood

An engine can last anywhere from 50 to 500,000 miles depending mostly on how well you maintain it. While some engines are certainly more reliable than others, all of them depend on maintenance to fulfill their greatest potential. Craig Johnson Automotive in Rowland Heights, CA has provided for you some of the determining factors of engine lifespan, to help you make sure your engine lasts as long as it possibly can.

fleet of vehicles

The heads on your commercial or fleet diesel are one of the most integral parts of your engine. The heads are comprised of the valvetrain, exhaust ports, intake ports, and injector ports. In essence, a head’s purpose is to regulate and time the intake of fresh air, the release of exhaust, the compression of fuel and air that provides combustion, and the entry point for fuel into the cylinder. The head is where all the complex aspects of engine operation occur...without it, you just have a chunk of metal with pistons in it, and no way to make them move. Here’s what you need to know about your heads, from Craig Johnson Automotive in Rowland Heights, CA.

checking your a/c coolant

Your vehicle's cooling system is one of the most important systems in your vehicle. Inside your engine, spark plugs ignite the fuel within the cylinders to produce small explosions that propel your vehicle down the road. With small explosions comes scorching temperatures that can destroy your engine if not controlled. There are two types of cooling systems - liquid-cooled and air-cooled.
