To find the correct CCA rating, you need to:
1. Check your existing battery: The CCA rating is usually printed directly on the battery's label.
2. Consult your owner's manual: This will give you the recommended group size for your Windstar. Knowing the group size (e.g., Group 35, Group 65) will help you find appropriate replacement batteries at an auto parts store. They'll show you the CCA for different batteries of that size.
3. Check an auto parts store website: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search for batteries by vehicle year, make, and model. This will show you suitable replacements and their CCA ratings.
Without knowing the specific battery installed in your 1995 Windstar, I cannot give you a definitive CCA number.
