As others have said, drain oil and coolant. Tap on 2 bolts that hold pump on before trying to loosen. It's a 30 minute job including draining oil, coolant, and replacing the pump. 8mm and 10mm sockets and screw driver to loosen hose clamp. 17mm on the oil drain.
You just have to find a pump at a dealer, or order one from a dealer that you will be at in a few days.
Don't ask how we know you have to drain the oil first...

Good luck and let us know how it goes. If I was there, I'd change it for you.
