CoolCop fits all years of the Chevy Tahoe and the 2020+ years of the Ford Explorer. The Universal fits most, but not all, cars, trucks and SUVs. Check out CoolK9 for your K9 partners or Working Dogs. CoolCop does not fit the Dodge Charger or the Ford Taurus Interceptor, or the 2012-2019 Ford Explorer Utility Interceptor. These specific vehicle models are available. CoolCop installs using a variety of clips and is a semi-permanent installation. CoolCop comes complete with a dash cup that measures 5 1/2″ x 3 1/2″, (14 cm x 9 cm) a 6 foot hose and a vest nozzle. Installation in some vehicle requires the use of zip ties to secure the base plate. CoolCop does not fit on a vent that has more than 1/2” of curvature as measured from a straight edge.
