Installing a Block Heater in a CAT 226B Skid Steer

[MikePhua]

Installing a block heater in your CAT 226B skid steer is a great way to ensure your engine starts more easily during cold weather, especially in areas that experience freezing temperatures. Block heaters warm up the engine coolant, helping to reduce engine strain and extend the life of your equipment. Below, we’ll walk through the process of installing a block heater in a CAT 226B, offering useful insights and tips for a smooth installation.
Why Install a Block Heater?
Block heaters are typically installed in colder climates to make it easier for diesel engines to start in freezing temperatures. When the engine is cold, the oil thickens and the battery’s capacity to start the engine decreases. The block heater prevents this by warming the engine block, making it easier for the engine to start and reducing wear. It also helps the engine run more efficiently after startup.
Choosing the Right Block Heater
Before starting the installation process, it’s crucial to choose the right block heater for your CAT 226B skid steer. The engine’s model and size will determine the appropriate type of block heater. It is recommended to use the manufacturer’s specifications to ensure compatibility with your skid steer. Additionally, block heaters come in different designs, such as:

• Frost Plug Heaters: These are the most common type for diesel engines. They are installed where the engine block’s frost plug is located.
  
• Heating Pad: This type is placed on the engine block to heat it directly.
  

For the CAT 226B, a frost plug heater is typically the best option as it fits well with the engine design.
Tools and Materials Needed
Before beginning the installation, gather the following tools and materials:

• Block heater (frost plug type)
  
• Socket set and wrenches
  
• Torque wrench
  
• Screwdrivers
  
• Electrical wiring and connectors (if necessary)
  
• Anti-seize lubricant
  
• Rags or towels
  
• Safety gloves
  

Steps to Install the Block Heater

1. Prepare the Equipment
   • Park the CAT 226B on a flat, stable surface and engage the parking brake.
     
   • Disconnect the battery to avoid any electrical hazards during the installation.
     
2. Locate the Frost Plug
   • The frost plug is usually located on the engine block. It may be helpful to consult your skid steer’s manual for the exact location. In many cases, it is on the side or rear of the engine block.
     
   • Use a flashlight if necessary to identify the frost plug clearly.
     
3. Remove the Frost Plug
   • Using a socket set and wrenches, remove the existing frost plug. This may require a bit of force, as the plug can be tightly secured in place. Use a hammer to carefully tap it out, or a specialized tool designed for frost plug removal.
     
   • Be cautious during this step to avoid damaging the engine block.
     
4. Install the Block Heater
   • Once the frost plug is removed, clean the area where the heater will be installed. Apply anti-seize lubricant around the rim of the frost plug hole to help with future removal.
     
   • Insert the new block heater into the hole, ensuring it is seated properly. Depending on the model of block heater, it may come with a sealing washer or gasket that should be placed in position.
     
   • Tighten the heater securely using a socket and wrench, but be careful not to overtighten it as this could damage the block or heater.
     
5. Reassemble and Connect Electrical Wiring
   • If your block heater requires electrical connections, follow the manufacturer’s instructions to wire it properly. Most block heaters have a power cord that extends from the heater and connects to an external power supply.
     
   • Ensure the wiring is routed safely and securely, avoiding any moving parts or areas prone to heat damage. Use zip ties or other fasteners to secure the wires.
     
   • Reconnect the battery to restore electrical power to the skid steer.
     
6. Test the Installation
   • Once the block heater is installed and the electrical connections are secure, it’s time to test the heater. Plug the heater into a power source and allow it to warm up for several hours before attempting to start the engine.
     
   • Check for any leaks around the heater area and ensure that it is operating correctly. The engine should turn over more easily once the coolant is warmed.
     

Final Tips

• Regular Maintenance: Make sure to periodically check the block heater for wear and tear, as well as the connections for corrosion. Clean any dirt or debris that may accumulate around the heater to ensure optimal performance.
  
• Use the Heater Wisely: When temperatures are very cold, plug in the block heater a few hours before you plan to use the skid steer. For temperatures slightly below freezing, a shorter time (1-2 hours) may suffice.
  
• Winter Safety: Always follow proper safety procedures when working with electrical components and engine parts. Wear gloves and safety goggles to protect yourself during the installation.
  

Conclusion
Installing a block heater in your CAT 226B skid steer is a simple and effective way to ensure it starts smoothly in cold weather. By following the steps outlined above, you can easily perform the installation yourself and avoid the frustration of dealing with a frozen engine. Not only will it improve the overall reliability of your skid steer during winter months, but it will also help extend its lifespan by reducing engine wear.
