The drain plug on the radiator should be on one of the lower corners of the radiator on your 1990 Pontiac Trans Sport. If you cannot find it removing the lower radiator hose at the radiator may be the best way to drain the cooling system. Please remember that coolant is considered a hazardous waist and any old coolant should be disposed of properly.
