99 tj coolant.

Putting in new radiator. Found a lot of things saying coolant recommendations were switched in early 2000's. If someone would clarify if that switch was for previous tj models also.

In 2001 TJs switched to HOAT coolant. Problems arise when coolants are mixed. Stick to what you have unless prepared to do full flush. If prepared to do a full flush run what you choose.

Yep. As biff said they changed coolants in 2001.

Always look both ways before crossing the stream.
