Setting a budget was essential in my buying process. I researched the typical price range for coolant reservoirs compatible with the Kenworth T680. This helped me find options that fit my budget while still meeting my quality standards. I learned that investing a little more upfront could save me money in the long run through reduced maintenance costs.
