coolant

[chuck172]

I'm over 2 years and need to change the anti-freeze. Should I flush or just drain/refill? Use distilled water or just get a pre-mix? What's the best antifreeze to get?

I simply flush mine with tap water, close it up and run till normal operating temp, drain and fill with (Fleet Guard) brand anti-freeze from TSC, mixed 50/50 with distilled water. The small amount of coolant required is inexpensive and over-kill IMO, but it keeps me happy

Just drain and refill. Mixed 50/50 with clean tap water. Just like you do on anything else. I don't know if any brand is better than the other.

I drain than run water thru 10mins or so than drain follow by 50/50...no problems.

I drained and put in a cleaner. It wasn't much $$ and the tractor is a significant investment. After 15 minutes of idle, I drained that to dispose of with the green conventional coolant and added pink extended life with a 50/50 mix of distilled water.

I drain, refill with plain water, run the tractor for 10-15 minutes and drain. Refill with concentrate that I mix 50/50 myself. I use 5 year extended life antifreeze.

I have a gal of 5o/5o DexCool "permanent" that I'd like to use in my CK30 and get rid of the green stuff. Any reason not to use it?

Many thanks for the feedback and refs. I read thru them both with interest and have come up with the Peak Fleet Charge sold by Tractor Supply near me. It meets the Astm 6210 and many others:
