Advice Needed ASAP on water pump, fan clutch

[e30mpower]

So I was convinced by another poster to take my 3.0 in for a cooling system inspection today. I had a chirping noise coming from the front that I only heard at idle. They assured me that this was from the drive belt which had a glaze on it, but that I shouldn't be concerned and they would clean it. My pulleys were inspected in May and were found to be OK.

The shop said that my water pump was "seeping," along with my fan clutch. He said that the water pump was a top priority, but the fan clutch, while on its way to failure, could wait for a little while. He also said that my expansion tank cap and bleeder screw needed to be replaced. I know all about catastrophic failures of the water pump, that's why I'm hesitant to drive it until I get it replaced.

I'm leaving for a camping trip this evening and was going to take my Expedition, but lo-and-behold it's in the shop as well. Is it safe to drive the X >350 miles (highway) before I can get the pump replaced on Monday?

Thanks for any help.

Oh, the truck is at 70,550 mi., which is at threshold of pump failure.
