2. Important Safety Information
Always prioritize safety when working on your vehicle. Failure to follow these guidelines may result in injury or damage to your vehicle.
- Ensure the engine is completely cool before beginning any work on the cooling system. Hot coolant and engine components can cause severe burns.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Work in a well-ventilated area.
- Dispose of old coolant properly according to local regulations. Coolant is toxic.
- Do not open the radiator cap or coolant reservoir cap when the engine is hot.
- If you are unsure about any step, consult a professional mechanic.
3. Package Contents
Your Mishimoto MMHOSE-RSX-02BL kit includes the following components:
- Upper Radiator Hose (Silicone, Blue)
- Lower Radiator Hose (Silicone, Blue)
Note: Hose clamps are typically not included and should be purchased separately if new ones are required.
4. Installation Instructions
4.1 Tools Required
- Socket Wrench Set
- Pliers (for hose clamps)
- Drain Pan
- Funnel
- Coolant (appropriate type for your vehicle)
- Rag or Shop Towels
4.2 Preparation
- Park the vehicle on a level surface and engage the parking brake.
- Allow the engine to cool completely. This is critical for safety.
- Place a drain pan under the radiator drain plug or lower radiator hose connection point.
- Carefully open the radiator drain plug or disconnect the lower radiator hose to drain the coolant.
4.3 Hose Replacement Procedure
- Once the coolant is fully drained, remove the existing hose clamps from the old radiator hoses.
- Carefully twist and pull the old hoses off the radiator and engine connections. Be prepared for any residual coolant.
- Clean the connection points on the radiator and engine to ensure a good seal for the new hoses.
- Install new or existing hose clamps onto the new Mishimoto silicone hoses before fitting them onto the connections.
- Slide the new upper and lower silicone radiator hoses onto their respective connections. Ensure they are fully seated.
- Position the hose clamps over the connection points and tighten them securely. Do not overtighten, as this can damage the hoses or connections.
- Close the radiator drain plug (if applicable).
- Refill the cooling system with the appropriate type and amount of coolant. Use a funnel to prevent spills.
- Bleed the cooling system of any trapped air. This typically involves running the engine with the radiator cap off (or reservoir cap open) until the thermostat opens and coolant circulates, topping off as needed. Consult your vehicle's service manual for specific bleeding procedures.
- Inspect all connections for leaks after the engine has reached operating temperature and cooled down again. Top off coolant if necessary.

5. Operation
Once properly installed, the Mishimoto silicone radiator hoses function as a direct replacement for your vehicle's original hoses, facilitating the flow of coolant between the engine and radiator. They are designed to withstand higher temperatures and pressures, contributing to a more reliable and efficient cooling system under various driving conditions.
6. Maintenance and Care
To ensure the longevity and optimal performance of your Mishimoto silicone radiator hoses, consider the following maintenance tips:
- Regular Inspection: Periodically inspect the hoses for any signs of wear, cracks, swelling, or leaks. Check the hose clamps for tightness.
- Cleanliness: Keep the hoses free from oil, grease, and other contaminants, which can degrade rubber and silicone over time.
- Coolant Quality: Ensure your cooling system uses the correct type of coolant and that it is maintained at the proper level and concentration.
- Avoid Abrasion: Ensure hoses are not rubbing against other engine components, which could lead to premature wear.
7. Troubleshooting
If you encounter issues after installation, refer to the table below for common problems and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Coolant Leak at Hose Connection | Loose hose clamp; Damaged hose or connection point; Incorrect hose seating | Tighten clamps; Inspect hose and connection for damage and replace if necessary; Re-seat hose fully |
| Engine Overheating | Air in cooling system; Low coolant level; Other cooling system component failure (e.g., thermostat, water pump) | Bleed air from system; Top off coolant; Diagnose and replace faulty components |
| Hose Appears Swollen or Collapsed | Excessive pressure/vacuum; Internal damage; Contamination | Inspect cooling system for pressure issues (e.g., faulty radiator cap); Replace hose if damaged |
If troubleshooting steps do not resolve the issue, contact Mishimoto customer support or a qualified mechanic.
