The CAT 246 skid steer loader is known for its versatility and reliability on construction sites, landscaping jobs, and other heavy-duty tasks. However, like all machinery, maintaining its components is essential to ensuring optimal performance. One common maintenance issue for skid steer owners is understanding how and where to connect heater hoses, which play a crucial role in the machine's heating system.
Whether you're working in cold weather conditions or looking to add or replace a heater system, knowing the correct way to connect the heater hoses is important for both functionality and safety. This article will walk you through the necessary steps to ensure that your heater hoses are connected properly on a CAT 246, providing useful tips, common challenges, and additional insights into the importance of the machine’s cooling and heating systems.
Understanding the Heater Hose System in the CAT 246
The heater hoses in your CAT 246 skid steer are responsible for circulating coolant from the engine to the heater core. This system is especially important in colder climates, as it keeps the operator warm and prevents freezing of critical components like the engine and hydraulic systems.
The heater itself draws coolant from the engine cooling system, which is then heated and circulated through the cab area by a fan. The coolant returns to the engine, where it is again heated and continues circulating in a closed-loop system. Heater hoses are typically made of rubber and connected to the engine’s water pump and heater core.
Common Issues with Heater Hose Connections
A few problems may arise when connecting or replacing heater hoses, and being aware of them can save time and trouble in the long run:
Correctly identifying where to connect the heater hoses is key to maintaining a well-functioning system. The CAT 246 has two primary connections for the heater hoses: one for the inlet and one for the outlet.
While properly connecting the heater hoses is important, there are other related factors to consider for the optimal performance of your CAT 246's heating system:
A user shared their experience of replacing the heater hoses on their CAT 246. They explained that after the hoses were installed, they took the machine out in cold weather and noticed that the cab was not warming up as expected. Upon further inspection, they discovered that the inlet hose had been routed incorrectly, reducing the flow of coolant to the heater core. By rerouting the hose and securing all connections, the problem was resolved, and the cab heater worked as intended.
Another operator had trouble with leaks after replacing the heater hoses, despite using brand new hoses and clamps. The issue was traced back to a worn-out connection point on the engine block. After replacing the damaged part, the system functioned perfectly.
Conclusion: Ensuring Proper Heater Hose Installation
Proper installation and maintenance of the heater hoses on your CAT 246 skid steer are crucial for ensuring reliable operation, especially in cold weather. By understanding where to connect the hoses and following the tips provided, you can ensure the heater system performs optimally, keeping the operator comfortable and preventing freezing-related damage. Regular maintenance checks and using the correct coolant will further help keep your machine in good working condition for years to come.
By staying proactive and informed, operators can avoid common problems and keep their skid steer performing well throughout the seasons.

Common Issues with Heater Hose Connections
A few problems may arise when connecting or replacing heater hoses, and being aware of them can save time and trouble in the long run:
- Leaks: One of the most common issues with heater hoses is leaks, which can occur at the hose connection points, often due to improper tightening or deterioration of the hose material. Leaking coolant can cause the heating system to fail and could potentially lead to engine overheating.
- Incorrect Routing: Ensuring that the heater hoses are routed correctly can be a challenge. If the hoses are not routed in the right direction, coolant might not flow efficiently through the heater core, leading to poor cabin heating and potential engine cooling issues.
- Clogged Heater Core: Over time, dirt, rust, or other debris can clog the heater core, reducing the flow of coolant. This can cause a decrease in heating performance and potentially damage the entire system.
- Worn or Damaged Hoses: Like other rubber components, heater hoses can degrade due to age, heat, and pressure. Worn-out hoses may need to be replaced, which can require disassembling parts of the machine’s engine compartment to access the heater lines.
Correctly identifying where to connect the heater hoses is key to maintaining a well-functioning system. The CAT 246 has two primary connections for the heater hoses: one for the inlet and one for the outlet.
- Inlet Hose Connection: The inlet hose connects to the engine’s water pump, where coolant is drawn into the system. On the CAT 246, this connection is typically located near the water pump, which is at the front of the engine compartment.
- The coolant flows from the water pump through the inlet hose into the heater core. The inlet hose should be connected firmly and securely to prevent any coolant leakage, which could compromise the entire system.
- The coolant flows from the water pump through the inlet hose into the heater core. The inlet hose should be connected firmly and securely to prevent any coolant leakage, which could compromise the entire system.
- Outlet Hose Connection: The outlet hose returns the coolant from the heater core back to the engine. On most models, the outlet hose connects near the top of the engine block or close to the thermostat. This is where the heated coolant is sent back to the engine to maintain optimal temperature levels.
- It's important that the outlet hose is routed without any kinks, as this can restrict the coolant flow and affect heating performance.
- It's important that the outlet hose is routed without any kinks, as this can restrict the coolant flow and affect heating performance.
- Ensure Proper Hose Length: When replacing or installing heater hoses, always check that the new hoses are the correct length. Too short, and the hoses might not reach their connections; too long, and you risk improper routing, which can cause coolant flow issues.
- Use Quality Hose Clamps: Secure the hoses with sturdy, corrosion-resistant hose clamps. Over time, hose clamps can wear out, leading to leaks. Tighten them securely, but be careful not to overtighten, as this can damage the hose.
- Check for Leaks After Installation: After connecting the heater hoses, it’s important to check the system for leaks. Run the engine for a few minutes and inspect both the inlet and outlet hoses for any signs of coolant leakage. This will ensure that the system is working properly.
- Consider Hose Insulation: In colder climates, it’s a good idea to insulate the heater hoses. This can help maintain the temperature of the coolant as it travels from the engine to the heater core, enhancing cabin heating and reducing the risk of freezing.
While properly connecting the heater hoses is important, there are other related factors to consider for the optimal performance of your CAT 246's heating system:
- Coolant Quality: Always use the recommended coolant type for your CAT 246. Poor-quality coolant or the wrong mixture of antifreeze and water can cause issues with the heater and cooling systems, including corrosion and blockages in the hoses.
- Regular Maintenance: Regularly check the heater hoses for signs of wear, cracks, or leaks. It’s a good idea to inspect the heater core and coolant lines at every service interval to ensure everything is functioning properly.
- Winterization: If you plan to store your CAT 246 during the winter months, make sure to winterize the machine. This includes draining any remaining water from the system, checking the coolant levels, and ensuring that the heater hoses are properly protected from freezing temperatures.
