An update on the leaking cooling system.

Was under it looking for the leak and found a real nasty and corroded driver
side coolant pipe. It looks like it has a few areas that are wet or are very
suspicious.
Another area of interest is the thermostat housing. There is some green
crusties
around. O-ring leaking-seeping. Pulled the cylinder tin off and found
nothing.

Can any one recommend a pressure tester so I can purchase one and properly
check the system out?
