Either the top radiator hose is leaking, the top hose radiator fitting is cracked or the side tank seal or plastic tank itself is leaking.

Your system has either a 16 or 18 psi cap, and as the coolant heats and expands (normal) system pressure rises and cracks squirt happily.

2001 - Probably new radiator and hoses time.

New radiator and hoses, retail parts at a good local shop - about $200, 2.5 hours labor. ~$400 - $500 total with coolant.

thanks a lot, I've previously un/installed my power steering pressure hose properly (to skip labor costs), I'm looking forward to this job. Ive heard its not that gruesome to pull the radiator out.

It is a pretty easy job. When mine went bad, it was easy to tell that the plastic on the side of the radiator was cracked. When the system pressurized, it would spray from the crack.
