cdog,
If your catch tank has a petcock on the bottom, open it and drain it into a bucket. The small hole in the top (from witch your coolant is bubbling) is an "overflow" which means that the tank is full. The EPA doesn't like an overflow hose draining right out to the ground, like in the old days, which is now the reason for catch tanks. I have a Jaz catch tank on mine and had to do this once at about 1500 miles. Then check coolant level in puke tank. As far as the clunks, like ERA535 advises, get under your car and check ALL nuts and bolts. Good Luck
