hello all. i was wondering if someone could help me with a seemingly simple problem. i don't know where to drain the radiator in my deville to take out the coolant and fill it with new stuff. i can't find the plug or stopcock anywhere. on the left side of the car, on the back of the radiator there is a small plastic piece that may be it but it is almost impossible to reach due to position and a large metal outlet above it. i can't understand where it would be but tis is a poor piece of engineering. if someone could let me know what they think, i'd appreciate it.
