Bad water pump... OK to drive?

I'm installing a new water pump in two days. It's leaking BADLY. Is Jeep safe to drive for next two days? or could I hurt something? I'm going through water by the bottles. Should I park her (a.k.a. take a sick day) or drive it.

The more you drive it, the more it is going to leak. Also the more chance you have for engine damage.
Your decision but I would not do it. Take a 1/2 day and redo the pump.

as long as your keeping enough coolant in your cooling system you can't really do that much damage since you have to replace the pump anyways. You may be able to slow the leak by opening your hood and loosening your radiator cap. Radiator caps (the metal ones) have 2 different settings......all the way tight and then half way tight (ever noticed takin them off they get super loose but are still hooked on?) that is what you want. When the cap is in that loose but still hooked stage it is venting the 15-16lbs. of pressure that runs through your system. the reason that the systems are under that pressure is because for every pound of pressure coolant will actually RAISE its boiling point by 3 degrees..... that being said...when you loosen that cap your coolant is going to be more suseptible (sp?) to boiling over.......but dont' won't boil over under normal opperating conditions
