Aeroflow's engine and transmission competition oil coolers are a fin and plate design which provides more surface area for optimal cooling of any fluid in all applications. Each cooler is fitted with high quality 12-volt 9” electric fan which flows up to 500CFM with only a 6 AMP draw for maximum cooling efficiency. The M18 x 1.50mm thermal switch located on the top of each cooler activates this electric fan via a relay at 175°F/79.5°C. The cooler features built-in attachment points and rubber mounts are sold separately (AF72-4001), making mounting the cooler assembly a breeze. The cooler accepts engine oil, transmission and power steering applications and has been pressure tested to over 200psi. Available with either 1/2” NPT or -10 ORB female fittings for a perfect O-ring seal. Each cooler comes with thermostat wiring and electric fan wiring. The dimensions are 13-1/2”(342mm) x 9”(228mm).
