Motorcycle Coolant
I want to cover what type of motorcycle coolant I use. Before taking my recommendation, please refer to your service manual as this post may not apply to your make & model.
My first choice is Pro Honda HP coolant, since it is readily available at my local dealer. It sells by the quart for about $8.
My second choice, and probably the one I use most, is Prestone Extended Life Antifreeze/Coolant . I choose to buy full strength jugs and mixing them myself with distilled water to 50/50. This type of coolant is available in 50/50 premixed for about $12/gal, while full strength is $14/gal. If I purchase a gallon of distilled water for $1 & full strength jug for $14, I can make 2 gallons of coolant for $15, or $7.50 per gallon.
The Prestone coolant mentioned above is phosphate, silicate, & borate free. Why is this important? Well, silicates can act as abrasives that may prematurely wear out water pump seals in motorcycles.
Hi Matthew,
Thank you for the info on coolant. I have a Honda cmx300, rebel. Someone send me a coolant from zerex Asian vehicle formula blue. The bike is from 2017. Could this work also for my bike? Live on a small island where the coolants are limited.. thanks
Says silicate free, I’d say you are safe to use it:
