Drain cooling system as follows:
a. If cooling system is still hot, carefully wrap a thick cloth around
the pressure relief cap and rotate slowly until pressure begins to
release. Step back until the pressure is released.
b. Then rotate pressure relief cap until free. Remove the pressure
c. Raise vehicle on hoist.
d. Remove splash shield from front of front sub-frame and body.
e. Open radiator draincock and drain the coolant system.
There you go.
I am not particularly ham fisted and rarely strip out fittings. However, I
have had bad luck on more than a few drain fittings on plastic radiators.
They seem to either leak upon tightening or break off. Therefore, what I
would do if it were my car would be to drain the radiator by disconnecting
the lower radiator hose. Consider replacing it if it is the original hose,
as it is 8 years old. Otherwise, just disconnect it, maybe replace the
factory spring clamp with an aftermarket screw type and leave the drain cock

Be careful tightening a screw clamp. Those flimsy plastic
tubes can shatter if they are tightened as much as is safe
on a brass radiator. Don't ask me how I know.
