Nothing to report yet.  Between work and holiday demands I haven't had much time to devote to the car not to mention we received a light dusting of snow last week that was met with a triple dose of salt on the roads killing some of my urgency to get this fixed.  The car is garage kept so I'm not at the mercy of the elements and expect to have some time available closer to Christmas to work on it.

I'm finally getting back to work on this coolant leak issue.  I removed the fan and shroud and the water pump pulley and can see coolant resting on the top of the passenger side of the timing chain cover.  I picked up a Powerbuilt cooling system pressure testing kit on loan from my local Advance Auto Parts yesterday.  Unfortunately none of the adapters in this kit fit the radiator neck of my car.  I'm a little surprised by this as I thought a 5.0L powered Fox body is far from exotic.  Anyway, what kit have you guys used to diagnose coolant leaks on your cars?

you can add air presure if you still have the throttle body coolant lines,, just cap off the TB end, then put air into the hose you took off.

You could do the same on a heater core hose, just dead end one end and add air to the hose you have hanging off.

i dont know how much air to inject but my gut tells me anywhere around 15psi of presure should start to reveal a air leak noise to help you pinpoint.

you will want to pinch off the radiator kneck bypass tiny line that goes to the over flow tank,,

actually dont go over i guess 19psi which is what i think the stock motorcraft caps were stamped with, i have a few that say 19psi i think.
