I've found a bit of a leak off my water pump, not sure that's where the leak is but just where it seams to be coming from. Oddly when parked, still warm at the shop the coolant system holds a pressure test. Any suggestions to help limp it to work for a few weeks of +/- 80km per day for a couple weeks until I can get in to a mechanic to get it fixed?

Guessing the shaft on the water pump is leaking instead of the gasket.. (if it is your water pump) Stop leak products like Bars leak have been used as temporary remedies, but they can clog your system and they're not great at stopping shaft seal leaks. That would also explain a brief pressure test passing.. you can watch the temp gauge and top off until you get it in that shop but that's risky because weep hole leaks usually mean the pumps internals are bad. Driving ~50 miles daily a day for 2 weeks is like 700 miles, IDK if I'd risk that, unless you have no choice.Oddly when parked, still warm at the shop the coolant system holds a pressure test.

keep antifreeze in the back of your trunk and fill it up frequently.
