YAMAHA Yamalube Pre-Diluted Antifreeze Coolant 1-Quart — 60/40 Ethylene Glycol, OEM Formula with Bittering Agent

YAMAHA Yamalube ACC-YAMAC-BL-32 is a pre-mixed, OEM ethylene-glycol antifreeze/coolant in a 1‑quart bottle formulated to protect Yamaha engines with a ready-to-use 60/40 coolant-to-water ratio and added bittering agent for safety.

This factory-made Yamalube antifreeze arrives ready to pour, eliminating guesswork about mixing ratios and ensuring consistent freeze and boil protection for water-cooled Yamaha motorcycles, ATVs, personal watercraft and small engines. Because it’s produced to Yamaha specifications, it matches the materials and performance expectations of Yamaha cooling systems and includes a bittering agent to deter accidental ingestion by children and animals. The 60/40 ethylene-glycol blend balances freeze protection, overheating resistance, and corrosion inhibition for aluminum and other metals commonly found in modern marine and powersports cooling circuits.

How does a pre-diluted 60/40 coolant simplify maintenance?

Pre-diluted coolant removes the need to measure or mix concentrate with water, saving time and reducing error. Using a factory-blended 60/40 solution gives predictable freeze and boil protection across a wide range of temperatures and helps maintain proper system corrosion control.

• Ready-to-use 1‑quart bottle: pour and go, no mixing required.
• Consistent 60/40 coolant/water ratio for reliable thermal protection.
• Reduces risk of incorrect dilution that can impair cooling performance.
• Convenient size for topping off or completing a full refill on small systems.

Will this Yamalube antifreeze work in my Yamaha water-cooled engine?

This product is formulated by Yamaha for use in Yamaha water-cooled engines and is compatible with systems designed for ethylene‑glycol based coolants. It is suitable for motorcycles, ATVs, side-by-sides, personal watercraft, and other Yamaha small engines that specify ethylene glycol coolant.

• OEM formulation matches Yamaha material compatibility and recommendations.
• Appropriate for aluminum and mixed-metal cooling systems found in Yamaha models.
• Ideal for top-offs, flush-and-refills, and seasonal service intervals.

Is the bittering agent safe and why is it included?

The bittering agent is a safety additive intended to reduce accidental ingestion by making the coolant taste unpleasant. It does not affect the coolant’s thermal or corrosion-protection properties and is commonly added to help protect children and pets during storage or in the event of spills.

• Bittering agent deters accidental ingestion but is not a substitute for safe storage.
• No impact on freeze/boil performance or corrosion inhibition effectiveness.
• Follow normal handling precautions: avoid skin contact and clean spills promptly.

Who is this for: This YAMAHA Yamalube 1‑quart pre-diluted antifreeze is aimed at Yamaha owners and service technicians who want an OEM-specified coolant that’s convenient and dependable. It’s especially useful for those who prefer a ready-to-use product for seasonal maintenance, trailside top-ups, or for anyone seeking the assurance of Yamaha-branded fluids engineered for compatibility with Yamaha cooling systems. Always consult your model’s owner manual for service intervals and coolant specifications before use.
