PEAK All Vehicles 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems, Long-Lasting Yellow Engine Coolant/Antifreeze for Year-Round Protection, 1 Gal.

Works as a prediluted antifreeze and coolant for your car's engine. No need to buy 100% antifreeze/coolant when this product is available and you simply pour it in to your radiator or coolant overflow cannister. I trust the PEAK brand and bought this knowing it just works. I have mixed this product with other coolant and not had an issue with viscosity or heating issues, much less corrosion. It is also competitively priced with consistent quality.

One Goldwing is 40 years old this year. 1983 GL1100. 4 cylinder boxer motor. The second one a 1990 GL1500 is a 6 cylinder boxer motor. Both call for silica free coolant as it wears the internal components and will cause them to corrode and fail. This is supposed to good for aluminum motors and seems to suggest that it is high performance coolant. I have now rode both bikes in busy downtown traffic and the temp gage rises up to normal fan click on temps them back down again. No over heating. But it didn’t before the coolant change either. But it works and that’s good for me. Seems to do it’s intended job. Now let’s see if it last the claimed 10k miles

Worked fine no issues great price too

Worry free, does the job well. John Force isn’t wrong.

This PEAK 50/50 prediluted antifreeze and coolant is a good option if you want something simple and ready to pour without mixing concentrate with water yourself. I like that it is already blended, especially for quick top-offs or routine maintenance. The biggest benefit is convenience. With some coolant products, you have to make sure the water ratio is right, but this one is already 50/50, so it takes out that extra step. That makes it easier to keep on hand in the garage for cars, trucks, or other vehicles when the coolant level needs attention. I also like that it is labeled for all vehicles and all engine cooling systems. That makes it less stressful when you are trying to pick the right coolant, especially if you have more than one vehicle at home. I would still always check the owner’s manual first, but the broad compatibility is a nice feature. The fluid pours cleanly, works as expected, and gives me confidence that I am using a proper coolant mixture instead of guessing. It is a practical garage item that is worth having around before you actually need it.
