Customer Questions & Answers
-
Question:
What is the purpose of the MOTOKU High Pressure Radiator Cap with Temp Gauge?
Answer: The MOTOKU High Pressure Radiator Cap with Temp Gauge serves to enhance the cooling system of your Honda motorcycle or ATV by maintaining optimal pressure. By regulating pressure at 1.8 Bar, it prevents coolant from boiling and increases the boiling point of the coolant, which is crucial for high-performance vehicles. Additionally, the integrated temperature gauge allows you to monitor engine temperature, helping to prevent overheating. This feature is particularly valuable during intense riding conditions or competitions. -
Question:
Is this radiator cap compatible with all Honda models?
Answer: The MOTOKU radiator cap is specifically designed for selected Honda models including CR125R, CR250, CR500R, CR80, CR85, CRF250L, CRF450R, TRX450R, and Rancher 420. Its compatibility ensures that you can easily replace your current radiator cap with a product that fits perfectly, maintaining the integrity of your cooling system. Always check your motorcycle or ATV model to confirm compatibility before making a purchase to ensure proper functioning. -
Question:
How do I install the MOTOKU High Pressure Radiator Cap?
Answer: Installing the MOTOKU High Pressure Radiator Cap is a straightforward process. Align the cap with the radiator opening and rotate it clockwise until it clicks into place. Make sure the engine is cool before installation to avoid burns or injury. Proper installation is crucial, as a secure fit ensures that the cap can effectively maintain the required pressure necessary for optimal cooling. This cap can be particularly useful for off-road riders who demand high performance from their vehicles. -
Question:
Can the temperature gauge be relied upon for accurate readings?
Answer: Yes, the integrated temperature gauge in the MOTOKU radiator cap provides reliable readings for engine temperature. It allows you to monitor real-time temperatures while riding, which is essential for preventing overheating and engine damage. Understanding your engine’s temperature can help you make informed decisions during your ride, particularly in challenging terrains or during prolonged use. Regular monitoring contributes to better engine performance and longevity. -
Question:
Will this radiator cap improve my motorcycle's performance?
Answer: While the primary function of the MOTOKU High Pressure Radiator Cap is to help maintain coolant pressure, this can indirectly enhance your motorcycle's performance. By preventing coolant from boiling and enabling the engine to operate at optimal temperatures, it helps maintain performance efficiency during rides. Riders who push their vehicles to the limits will find this cap beneficial, especially in maintaining consistent power output during demanding conditions. -
Question:
What maintenance do I need to perform on the radiator cap?
Answer: Maintaining your MOTOKU High Pressure Radiator Cap is essential for its longevity and performance. Regularly check the cap for any signs of wear, damage, or corrosion, particularly after off-road rides that may expose it to harsh conditions. Clean the gasket area with a soft cloth to ensure a tight seal to prevent leaks. Performing these basic maintenance steps ensures that the cap continues to function effectively, safeguarding your engine's cooling system. -
Question:
What happens if I use a radiator cap with the wrong pressure rating?
Answer: Using a radiator cap with an incorrect pressure rating can lead to multiple issues, such as coolant overflow, overheating, or even damage to the cooling system. A cap designed for a lower pressure may allow coolant to boil prematurely, while one rated too high could put excessive strain on the radiator system. It's crucial to select the right cap, like the MOTOKU 1.8 Bar cap, to maintain safe operating temperatures and improve overall engine performance. -
Question:
Can I use this cap for other vehicles outside of Honda models?
Answer: The MOTOKU High Pressure Radiator Cap is specifically designed for select Honda models, ensuring a snug and proper fit. While it may physically fit onto other vehicle brands, it is not recommended to use it due to different pressure specifications and design requirements. Using a cap not intended for your vehicle could compromise the cooling system's efficiency. Always refer to your owner’s manual for the appropriate parts for your motorcycle or ATV. -
Question:
How does the pressure rating affect the cooling system?
Answer: The pressure rating of a radiator cap, such as the 1.8 Bar rating of the MOTOKU model, impacts the boiling point of the coolant in your engine. Higher pressure prevents coolant from boiling, allowing the engine to run at a higher temperature without overheating. This is particularly important for performance vehicles or in environments where engine stress is increased. An optimal pressure rating not only extends engine life but also improves performance under demanding conditions. -
Question:
Where can I buy the MOTOKU High Pressure Radiator Cap with Temp Gauge?
Answer: You can purchase the MOTOKU High Pressure Radiator Cap with Temp Gauge from Ubuy in Brunei. Ubuy offers a wide selection of automotive parts and accessories, ensuring you find the right products for your needs.

MOTOKU Standard 16386-30001 Editorial Review
The MOTOKU High Pressure Radiator Cap with Temp Gauge appears to be a product that has received mixed feedback from customers. On one hand, some users have reported a perfect fit and satisfactory operation, particularly noting its accuracy in temperature readings during activities like waiting at stoplights. However, a significant number of reviews highlight serious issues related to the cap's reliability and quality. Several customers have experienced leaks, with one specific account noting that the cap worked well for two rides before it began leaking coolant from the overflow and failed to maintain pressure entirely. This led to concerns about overheating, which could have resulted in engine damage if not caught in time. Others have echoed similar sentiments, indicating that the cap shows signs of poor quality right from the start, with instant leaks upon installation. Overall, while the MOTOKU radiator cap may provide some initial benefits such as fit and functionality, its long-term reliability is questionable according to customer experiences. **
