Hello all, my 2000 V6 'Tour isn't putting out near the amount of cool air that I'm used to, and I'm thinking it's a lack of coolant. I see two different things under the hood that look like the low/high measuring/filling.. umm I guess you'd say receptacles : ) One is just behind the battery, the other is just behind the coolant overflow tank. Which one is the low? And is pathetically uncool air likely related to a lack of refrigerant?
