1. Check engine temperature
Never open the cooling system when the engine is hot. Wait until the motorcycle cools down – hot fluid under pressure can cause burns.
2. Locate the filler cap
Find the expansion tank or radiator cap according to your motorcycle's owner's manual. Usually the tank has MIN and MAX markings showing the proper coolant level.
3. Top up or replace coolant
If topping up: add OC1 Motorcycle Coolant to the MAX level on the tank. If replacing: drain old fluid through the drain plug at the bottom of the radiator, then pour in fresh product.
4. Bleed the system
After filling, run the engine for a few minutes with the cap open. Allow air bubbles to escape from the system. Top up fluid level if needed.
5. Check for leaks
When the engine is warm, check for leaks at hoses and fittings. Tighten hose clamps if necessary.
Important
Do not mix different fluid types (ethylene glycol vs propylene glycol). OC1 Motorcycle Coolant is compatible with ethylene glycol-based fluids. Do not apply on hot surfaces – wait until the engine cools down. Storage temperature: 5-25°C. Dispose of used coolant according to local regulations – do not pour into drains or soil.
Tip
The best time for coolant replacement is early spring (preparing the motorcycle after winter) or late autumn (before winter season). Regularly check coolant level – at least once a month during the season. If the level drops frequently, this may indicate a system leak – contact a mechanic. Keep the original bottle with label so you always know what you filled the system with.
Can I use OC1 Motorcycle Coolant in any motorcycle?
Yes, this coolant is compatible with most liquid-cooled motorcycles that use ethylene glycol-based fluids. Check your motorcycle's owner's manual for the fluid type recommended by the manufacturer. OC1 Motorcycle Coolant meets standard requirements for coolants used in road, touring and urban motorcycles.
What's the difference between OC1 Motorcycle Coolant and Ice Coolant Racing?
OC1 Motorcycle Coolant is the standard version with a boiling point of 130°C and freezing point of -25°C – ideal for everyday use in normal conditions. Ice Coolant Racing is the advanced version with a boiling point of 136°C and freezing point of -26°C, designed for sport and racing motorcycles that operate at extreme temperatures. For most users, the standard version is perfectly sufficient.
Do I need to dilute the fluid with water?
No. OC1 Motorcycle Coolant is ready to use – it has optimal concentration and requires no dilution. Simply pour it into the cooling system. Diluting could weaken the protective additives and change the coolant's operating parameters.
How often should I replace the coolant?
We recommend replacing coolant every 2 years or according to your motorcycle manufacturer's recommendations. Coolant loses its protective properties over time – anti-corrosion additives become depleted and the product itself may become contaminated with deposits. Regular replacement ensures engine protection.
What should I do if the fluid level drops frequently?
If you need to top up coolant often, this is a sign that the cooling system has a leak. Check hoses, clamps and water pump seals. If you can't find the leak yourself, visit a workshop – ignoring the problem can lead to engine overheating.
Can I add OC1 Motorcycle Coolant to another fluid?
Yes, if the system contains ethylene glycol-based fluid, you can safely add OC1 Motorcycle Coolant. However, best results are achieved with complete coolant replacement – then you're certain the entire system is filled with fresh, full-quality product.
Does the fluid protect against rust and corrosion?
Yes. OC1 Motorcycle Coolant contains anti-corrosion additives that create a protective layer on metal cooling system components. This extends the lifespan of the radiator, water pump, hoses and all metal parts that contact the coolant.
How should I store unused fluid?
Store OC1 Motorcycle Coolant in its original, tightly sealed container at 5-25°C. Avoid direct sunlight and locations with extreme temperatures. Properly stored product maintains its properties for a long time.
What should I do with used fluid after replacement?
Used coolant is chemical waste and cannot be poured into drains, soil or regular rubbish. Take it to a chemical waste collection point or to a garage that accepts maintenance waste. This is important for the environment.
Can I use this fluid in winter for a motorcycle stored in an unheated garage?
Yes. OC1 Motorcycle Coolant protects the system against freezing down to -25°C. If you store your motorcycle in a garage where temperature may drop below zero, the fluid prevents radiator and engine block cracking. This is much safer than plain water, which freezes at 0°C.
How long does 2 l of fluid last?
The 2 l capacity is sufficient for complete fluid replacement in most motorcycles. Motorcycle cooling systems typically hold 1 to 2 l of coolant, depending on engine displacement and radiator size. Check your owner's manual for how much fluid your motorcycle requires.
Is the product safe for seals and rubber hoses?
Yes. OC1 Motorcycle Coolant is safe for all standard materials used in cooling systems, including rubber hoses, seals and plastic components. It does not cause swelling, brittleness or degradation of these elements.
