One list member used a bicycle pump, cut the end of the hose off and using whatever
tubing and clamps were necessary, attached it to the cap on the expansion tank, where
the overflow tube attaches. I used a 110 volt tire inflator. But these were to fill
and help bleed the cooling system. You don't want to put much pressure on  it, and I
am not sure it would help you find the leaks. If you see coolant on the gasket, it's
probably time to have the heads re-sealed.
