Yamaha FJR1300 Coolant Specifications & Problems

Proper cooling system maintenance is essential for the reliable performance and longevity of Yamaha’s FJR1300 sport-touring motorcycles.

As advanced touring bikes designed for long-distance rides, adequate cooling allows these machines to operate safely even under intense loads and hot operating conditions.

Yamaha FJR1300 Coolant Type

Yamaha recommends using their genuine YAMAHA Coolant anti-freeze for the FJR1300 sport touring motorcycle.

This is an ethylene glycol-based green coolant that meets Yamaha’s specific formulation to provide maximum corrosion protection for the FJR1300’s aluminum engine and cooling system components.

Yamaha’s Factory Coolant Specs:

  • 50/50 premixed solution of distilled water and concentrated coolant
  • Provides freeze protection down to -31°F/-35°C
  • Contains hybrid organic acid technology (HOAT) corrosion inhibitors

This OEM coolant exceeds industry standards for corrosion protection, with an expected change interval of 5 years or 30,000 miles when used as directed.

Yamaha likely spent extensive R&D testing this formula specifically in the FJR1300 to validate protection across a wide operating temperature range in on-road and track conditions.

While aftermarket coolants may make protection claims, Yamaha cannot ensure proper performance or damage protection if non-approved fluids are used.

To maximize reliability, the factory YAMAHA Coolant is recommended.

Aftermarket Coolants for Yamaha FJR1300

Many aftermarket coolant brands offer formulas claiming to meet or exceed OEM specifications.

However, specialized motorcycle coolants are not typically designed for a specific model’s metallurgy and operating conditions.

The Motul Motocool Factory Line coolant highlighted seems to offer impressive protection in standardized industry tests.

Yamaha FJR1300 Coolant Replacement

Yamaha FJR1300 requires ~3.2 liters of coolant.

At first, the motorcycle only takes 2.2 liters of coolant.

You can fill in more coolant after a few heat cycles, the reservoir will settle midway between the marks.

Add more coolant to the reservoir once this happens and the coolant level goes down.

FJR1300 needs a 50/50 mixture of coolant and water.

How to Replace the Coolant on FJR1300?

Loosen the fairing bolt on the right side of the motorcycle to drain the coolant.

Use a plastic rod to gently push the fairing aside, then wrap the surrounding area in a plastic bag to protect components from dripping coolant.

When ready, slowly loosen the drain bolt but do not fully remove it right away.

Allow the coolant to drain until the system is approximately half empty. This controlled draining prevents coolant from shooting out rapidly.

To drain the coolant reservoir, insert a small hose into the bottom of the tank.

Use a syringe to initiate siphoning via capillary action.

Once coolant begins flowing through the hose, remove the syringe while keeping the hose lowered below the reservoir.

This maintains continuous draining until nearly all coolant has emptied from the tank. Take precautions to capture the drained fluid.

FJR1300 Coolant Problems

Many FJR1300 coolant leaks originate from painted connection points. Over time, paint deteriorates, allowing seepage between rubber hoses and metal fixtures.

Especially problematic areas include the thermostat housing and smaller accessory lines. Slow seepage quickly drains the entire system since capacity is low.

Unfortunately, Gen 2 FJR1300 models lack a low coolant warning indicator, making small leaks a serious issue. Preventative maintenance is crucial.

Preventive Maintenance

Regularly inspect all hoses, gaskets, housings, and o-rings for cracking or looseness.

Tighten any loose clamps. Small leaks can be temporarily fixed using gasket sealants on hose connection points.

Sanding paint from metal surfaces improves seal integrity. Ensure rubber components show no dry rotting or brittleness.

Pressure testing cold systems helps locate leaks. Use spray lubricants on hoses to maintain suppleness and prevent cracking.

Drain/replace coolant based on mileage intervals, and flushing residue.

Coolant Safety Tips

Be careful when checking or adding coolant to the motorcycle as the radiator and hoses can get hot.

Allow time for the system to cool before servicing. Wear eye protection and gloves when handling coolant.

Check the amount of coolant occasionally to keep the motorcycle in condition.


Maintaining the proper FJR1300 coolant type and levels is crucial to ensure safe, consistent operating temperatures across varying riding conditions.

While the OEM Yamalube coolant offers extensive testing and formulation specifically for the FJR’s cooling system, quality aftermarket fluids meeting or exceeding industry standards can also be used.

Along with routine checks and fluid changes every 30k miles, fixing any leaks or seepage as soon as they appear prevents total system loss – especially important given the lack of a low coolant warning on Gen 2 bikes.

Equipped with this guidance, FJR1300 owners can make informed coolant decisions to support longevity and performance.
