We have been stocking these tanks for a while and they are proving popular. Every engine expels coolant as it gets hot – a small block Chevy, for instance, can push out up to a quart. That usually goes onto the floor, but with a recovery tank in the system the expelled fluid is drawn back in as the motor cools down. We stock three tank sizes, all in polished stainless steel with a knurled alloy screw cap. The three sizes are PB0 0700/13 = 13”, PB0 0700/15 = 15”, PB0 0700/17 = 17”.
