Aluminum Radiator Parts - Drain Plug

Today, vehicles have aluminium radiators with plastic Tanks. The Tanks are attached to the main core radiator and hole is drilled into them and a Plastic drain cock was inserted. Some of these Plastic Drain Cocks were threaded while others were designed to twist and lock. This aided the vehicles in draining out the coolant during a radiator or system flush without the mess.

A radiator Drain Cock or Plug is one of the more modern additions to vehicles to make maintenance of the cooling system easier. In older cars, a radiator had to be completely taken out for draining because of the absence of a radiator Drain Cock. With new cars equipped with the tiny device, draining a radiator has become easier than ever.
