Question Confusion: Cool-Gard vs Cool-Gard II...CONDITIONER?

From what I have gathered John Deere stopped production of the Cool-Gard product in 2008 and replaced it with Cool-Gard II. My pre-2008 manual provides that Cool-Gard is used but given that only Cool-Gard II is available then obviously it will be Cool-Gard II to be used. However, my manual states that for coolant replacement of Cool-Gard I am to add JD Liquid Coolant Conditioner RE23182 to the coolant as this is a diesel engine. But, for Cool-Gard II is RE23182 to be added or is there another conditioner that is to be added for full replacement of coolant?

It appears to me nothing needs to be added to Cool-Gard ll for 6 yrs or 6000 engine hrs

Re: Confusion: Cool-Gard vs Cool-Gard II...CONDITIONER?

I believe regular Cool-Gard had a similar product description except it was 5 years not 6 years. Only when I looked at the maintenance instructions did I learn about the additive requirement. Perhaps someone has a 2008+ tractor and can look up their maintenance manual for instructions of coolant replacement with Cool-Gard II so see if there is any mention of a coolant conditioner one way or another.

Additive is to be added to radiator with Cool-Gard ll when coolant test strips indicate it's required.

I was under the impression that test strips are used to monitor the coolant over time as the conditioner is "depleted" whereas my situation is a complete flush and changeover to Cool-Gard II rather than topping it off.

You're correct about test strips. I thought you were inquiring about Cool-Gard additive not Cool -Gard coolant.

Thank you for your help.

The answer is: When flushing out a system including ones that had used original Cool-Gard if you replace with Cool-Gard II then no additive is required since Cool-Gard II already has the additives that were not present in the original Cool-Gard formulation.

Re: Confusion: Cool-Gard vs Cool-Gard II...CONDITIONER?

As stated, no additive required at time of changing coolant. When test strips indcate additive is needed, DO NOT use Re23182. The corrrect additive for Cool Gard II is TY26603 coolant extender.
