Hyundai Sonata Complete Engines

Keep it fast and furious, or just practical and efficient, with the right engine for your Hyundai Sonata. Engine jargon is like a whole other language that frequently mystifies, but don't worry: It's simple enough to demystify the language around Hyundai Sonata engines and help you find the right one for your ride.

How do you know if you need a long block in the sedan?

A Hyundai long block replacement is advisable if its component short block and attached head are damaged irreparably. The long block is essentially the engine head bolted to a short block. Long blocks typically have more parts at the time of installation although they may still require some additional external parts, such as the valve covers, oil pan, and the intake and exhaust manifolds

If you already have these parts from an existing engine, then you won't need to purchase any additional parts for the vehicle.

When should you get a Hyundai short block?

If your sedan's current engine short block is damaged beyond repair, consider purchasing and installing a short block. Installing a short block gives you the opportunity to customize the parts, like adding a turbo. For example, since a short block is a sub-assembly that requires building, you can bore out the actual engine for more cylinder capacity.

You can install a premium camshaft, and you can balance out rotating assemblies. These tweaks result in higher fuel efficiency and improved performance of the vehicle. Experts agree that short block work is extremely accessible to both experienced mechanics and beginners or enthusiasts, which makes short blocks even more attractive.

What does DOHC stand for?

Dual overhead camshaft, or DOHC, is a layout of valvetrain containing two camshafts within the cylinder head. DOHC has more space between intake and exhaust valves, improving airflow at high speeds. This spacious layout permits optimal room for the position of the spark plug. The DOHC spark plug position results in high-efficiency combustion.

What is the significance of Hyundai VIN C?

"VIN" stands for vehicle identification number. The "C" indicates the engine type and specific year, typically appearing in the eighth digit of a Hyundai Sonata VIN. "C" is the Hyundai Sonata VIN digit for a DOHC four-cylinder engine extracted from a Sonata released in a very specific calendar year. Other Sonata VIN codes and meanings are located in your owner's manual or online. These identifying numbers and letters convey pertinent information you or your mechanic may find helpful, such as:

  • Manufacturer
  • Body type
  • Trim Level
  • Manufacturing Plant
  • Manufacturing Month
What does Hyundai OEM Sonata engine mean?

"OEM" stands for Original Equipment Manufacturer. OEMs make complete engines for the Sonata or other Hyundai vehicles and sell them under an OEM brand name, such as LKQ and Keystone. Some experts believe that OEM products are the closest to the original Hyundai brand in terms of size, fit, compatibility, and quality. Your other brand options include private label and aftermarket engines. All are comparable choices, but most replacement Hyundai Sonata complete engines happen to be OEM.
