What engine coolant does the FZ6R require?

For the past couple of days I was researching what coolant to use to replace the original one.


This is what the service manual advise:

Recommended antifreeze
High-quality ethylene glycol antifreeze
containing corrosion inhibitors
for aluminum engines
Mixing ratio
1:1 (antifreeze:water)
Radiator capacity (including all
routes)
2.00 L (2.11 US qt, 1.76 Imp.qt)
Coolant reservoir capacity (up to
the maximum level mark)
0.25 L (0.26 US qt, 0.22 Imp.qt)

I still haven't picked one, but it looks like I will go to the dealership and get 3 quarts of the OEM one (Yamacool High-Performance Antifreeze - ACC-YAMAC-L6-W), it's the cheaper way.

Yamaha Motor Corporation, USA - Lubricants & Grease Yamacool High-Performance Antifreeze.


Also I found the following articles helpful:

Antifreeze/Coolant-Brand - Yamaha FZ6 Forums - International FZ6 Motorcycle Community Forum

Choosing silicate free motorcycle engine coolant for Honda motorcycles



Safe options for the FZ6R, other then the Yamaha OEM, I would consider in the future:

AMSOIL Antifreeze and Engine Coolant ( ANT1G-EA )

Engine Ice

Evans NPG+


I will update more info as soon as I change the coolant (if time allows it maybe do a quick How To).

Yamaha says to replace the coolant every 16.000 miles or 24 months.

The description Yamaha provides suggests any of the major fluids would be ok. I believe all of them will fill those requirements. The Newer, longer lasting coolants are supposed to be interchangeable with the old green stuff. If you change your coolant every other year, you shouldn't have a problem with any of them. Check the side of the jug, if it says it "Meets or exceeds manufacturer requirements" It should be good. I doubt there is a dimes worth of difference between the major brands and the stuff sold under Superstore brands. it all comes from the same plants.

Any 50/50 coolant sold at commercial stores will be just fine. I know fz1 s are recommended 70water/30antifreeze, and anything less dilutednis fine. These are probable the same. Walmart supertek will work just fine.

use caution not to intermix glycol with some of the long life stuff and dont just rely on colors ive seen how some of the long life stuff turns to crystals in engines

Forgot about this thread. Changed my coolant 3 days ago actually, with Engine Ice. Let me tell you it was a disaster...

I was told to bump it, run it with the cap off then put the cap back on. I did, until it hit about 200 F then it started shooting!

Filled the rest with Distilled water and it runs fine. Have to say, the old coolant was nasty looking. Might be in my head but I'm running about 20 degrees cooler.

Dump a little down the drain every day. The EPA hasn't said if antifreeze is hazerdous or not and as long as the water treatment company doesn't get overloaded with gallons at a time, they can take care of it. Not recommended if you have a septic tank as it may kill some of the bacteria that break down waste in your water.

My source on this is my microbiology teacher who has a phd in microbiology and used to work for the cape girardeau treatment plant. I'm confident in her

We actually see this alot in cars,turns into sludge,actually found out the reason long life antifreeze turns bad is excessive air in cooling system most of the time caused by bad radiator cap,something usually overlooked on maint..Also allowing overflow tank to go empty will cause same problem....

This is what I heard as well. Otherwise I've also heard of people dumping the coolant in the oil and giving it to the autoparts place.

It is poisonous and will destroy the kidneys and kill any animal that drinks even a small amount of it so I don't see how it can be just poured down the drain.

That was according to my professor in cape Girardeau. I'm sure there are better sources out there, but as long as you don't have a septic tank, all water that goes down your drain goes through a water treatment plant before it is released to the earth. If you have a storm drain or basement drain, I believe they don't get treated so don't pour the coolant in there and you should be alright. Or like Mike said, trick the auto place into taking care of it
