- Case IH 685
- Case IH 695
- Case IH 885
- Case IH 895 (with AC)
Important: To ensure correct fitment, you must match your tractor's Original Equipment Manufacturer (OEM) part number to one of the following OEM part numbers:
- 83673C4
- 84673C3
- 84673C4
- 84673C5
- 84673C6
- 847673C5
Failure to verify OEM part number compatibility may result in incorrect fitment and potential damage.
Safety Information
Always prioritize safety when working with tractor components and cooling systems. Failure to follow safety precautions can result in serious injury or damage to equipment.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, gloves, and protective clothing.
- Engine Coolant: Engine coolant is toxic. Avoid skin contact and ingestion. Dispose of used coolant responsibly according to local regulations.
- Hot Surfaces: The engine and cooling system components can become extremely hot. Allow the engine to cool completely before performing any maintenance or installation.
- Pressure Release: Never open a hot radiator cap. Allow the system to cool and release pressure slowly by turning the cap to the first stop before fully removing it.
- Vehicle Stability: Ensure the tractor is parked on a level surface, the engine is off, and the parking brake is engaged. Use wheel chocks if necessary.
- Professional Assistance: If you are unsure about any step of the installation or maintenance process, consult a qualified mechanic.
Setup and Installation
The following steps outline a general procedure for replacing a tractor radiator. Specific steps may vary based on your tractor model. Refer to your tractor's service manual for detailed instructions.
- Preparation: Park the tractor on a level surface, engage the parking brake, and turn off the engine. Allow the engine and cooling system to cool completely. Gather necessary tools (wrenches, pliers, drain pan, new coolant, etc.).
- Drain Coolant: Place a suitable drain pan under the radiator draincock. Carefully open the draincock and the radiator cap (once cool) to allow the coolant to drain completely. Dispose of old coolant properly.
- Disconnect Hoses and Sensors: Disconnect the upper and lower radiator hoses from the radiator. If present, disconnect any fan shroud, overflow hose, or electrical sensors attached to the radiator.
- Remove Mounting Hardware: Locate and remove all bolts, clamps, or brackets securing the old radiator to the tractor frame.
- Remove Old Radiator: Carefully lift and remove the old radiator from the tractor. Be mindful of its weight and any remaining fluid.
- Inspect Area: Clean the radiator mounting area and inspect for any damage or corrosion.
- Install New Radiator: Carefully position the new Eagle Radiator into the mounting location. Ensure it sits correctly on its mounts.
- Secure Radiator: Reinstall all mounting hardware, bolts, clamps, and brackets. Tighten securely according to manufacturer specifications.
- Reconnect Components: Reconnect the upper and lower radiator hoses, overflow hose, fan shroud, and any electrical sensors. Ensure all connections are tight and secure to prevent leaks.
- Refill Coolant: Fill the radiator with the appropriate type and amount of new engine coolant as specified by your tractor manufacturer. Fill slowly to allow air to escape.
- Bleed Air: Start the engine and allow it to reach operating temperature with the radiator cap off (or partially open if specified by tractor manual) to bleed any trapped air from the system. Monitor coolant level and top off as needed. Once air is bled, replace the radiator cap.
- Check for Leaks: After the engine has run and cooled, thoroughly inspect all connections and the radiator for any signs of leaks.
Operating Principles
The radiator is a critical component of your tractor's cooling system, responsible for dissipating heat from the engine coolant. Proper operation relies on maintaining adequate coolant levels and ensuring unrestricted airflow through the radiator fins.
- Coolant Level: Regularly check the coolant level in the overflow reservoir and, when the engine is cold, in the radiator itself. Maintain the coolant level between the 'MIN' and 'MAX' marks.
- Temperature Monitoring: Pay attention to your tractor's engine temperature gauge. Consistent overheating can indicate a problem with the cooling system, including the radiator.
- Airflow: Ensure the radiator fins are free from debris (dirt, leaves, insects) to allow for efficient heat exchange. Blocked fins reduce cooling capacity.
Maintenance
Regular maintenance of your Eagle Radiator will help ensure its long life and optimal performance.
- Visual Inspection (Monthly): Inspect the radiator for any signs of leaks, corrosion, or damage to the fins. Check hoses for cracks or deterioration.
- Clean Radiator Fins (Quarterly or as needed): Use compressed air or a soft brush to gently remove dirt, dust, and debris from the radiator fins. Always blow air from the back (engine side) towards the front to push debris out. Avoid using high-pressure water directly on the fins, as this can bend them.
- Coolant Quality and Level (Monthly): Check the coolant level and condition. If the coolant appears discolored or contains particles, it may be time for a flush and refill.
- Coolant Flush and Replacement (Every 2-5 years or as per tractor manual): Follow your tractor manufacturer's recommendations for coolant flush and replacement intervals. Use only the specified type of coolant.
- Hose and Clamp Inspection: Periodically check radiator hoses for firmness and elasticity. Replace any hoses that are soft, brittle, or swollen. Ensure all hose clamps are tight.
Troubleshooting
This section addresses common issues related to the cooling system. If you encounter problems, consult this guide before seeking professional assistance.
| Symptom | Possible Cause | Solution |
|---|---|---|
| Engine Overheating | Low coolant level, blocked radiator fins, faulty thermostat, water pump failure, restricted coolant flow. | Check coolant level and top off. Clean radiator fins. Inspect thermostat and water pump. Check for kinks in hoses. |
| Coolant Leaks | Loose hose clamps, damaged hoses, radiator core damage, faulty radiator cap. | Tighten clamps, replace damaged hoses. Inspect radiator for visible damage. Replace radiator cap. |
| Low Coolant Level (Frequent) | External leak, internal engine leak (e.g., head gasket), faulty radiator cap. | Inspect entire cooling system for leaks. Consult a mechanic for internal leak diagnosis. Replace radiator cap. |
| Poor Heater Performance | Low coolant level, air in cooling system, clogged heater core. | Check and top off coolant. Bleed air from the system. Consult a mechanic for heater core issues. |
