Cylinder Heads

Cylinder heads may not grab headlines, but they are pivotal components in a truck’s engine. Attached to the top of the engine block, these parts seal off the cylinders to create a closed combustion chamber. The heads house crucial elements such as valves, spark plugs, and injectors, which all work in tandem to control the intake of air and fuel, as well as the exhaust of combustion gases. The design and condition of cylinder heads significantly influence an engine's performance and fuel efficiency.

Quality matters when it comes to cylinder heads. The construction material needs to be durable to withstand the intense heat and pressure generated by the engine. Most cylinder heads are made from either cast iron or aluminum.

• Material: Aluminum heads are lighter but cast iron heads offer greater durability.
• Valve Seats: Hardened valve seats can extend the component's lifespan.
• Cooling Fins: These dissipate heat and help keep the engine cool.
• Warning Signs: Time for a Replacement?

Recognizing when to replace the cylinder head is crucial for avoiding engine damage. Indicators that you might need a new one include:

• Overheating engine
• Loss of engine power
• Increased oil or coolant consumption
• Visible cracks on the cylinder head

Ignoring these signs can lead to severe engine issues that are both complicated and costly to repair.

Regular cleaning can extend the life of cylinder heads. Deposits can build up over time, reducing the engine's efficiency. It’s advisable to check for warping or cracking during routine engine maintenance and to replace the gasket to ensure a proper seal.

Choosing the correct cylinder head is no trivial task. In the Big Rig shop, you'll find a wide assortment of cylinder heads suitable for various makes and models. Whether it's a heavy-duty cast iron piece or a lightweight aluminum option, there's something for every need and budget. A truck equipped with the right cylinder head doesn’t just meet performance expectations—it exceeds them.
