Ok, I bought an 1990 e350 ambulance. 4600 hours, 115,000 miles. A modicum of rust (maybe 10" square on the visible body). I'm starting a business "Tech Rescue"...

Just changed the thermostat - The thermostat works now - but only after I bled air from the junction above the IP that had a red and blue hose connected to it... which decided to leak, so i replaced the metal valve with a plastic straight through connector.

I put in ~6 gal Compleat ES antifreeze 50/50

I lost the bottom right bolt for the alternator / vac pump bracket casting! (anyone know where I can get one?) I figure the 2 should be OK for a year or two...

I dinged the 165 amp alternator fan so it has a vibration now... Might have a shop replace it with a 200+ amp alternator...

I can't find the electrical clip that goes to the accessory bracket slot on the alternator
The alternator only makes 13 volts at high idle, amperage unknown

The PS pump clinks and I did check the level

I didn't drain the block, but I did flush with 10 gal of distilled water and drained through radiator drain... I'll top it up with DCA4 and ethlene glycol pure until it's spec.

So:

1.) How many hours of labor should I expect to have someone change out the PS pump? And is there a belt tensioner I can adjust (this might be the clinking?)

2.) How many hours labor is spec to swap the alternator?

3.) What was the thing I broke 10" right above the IP - it looks like a Z shaped block with a threaded screw through the whole thing... block off / air bleed metallic device hooked up to a red coolant hose and a blue coolant hose - I just spliced em together because it was leaking, what is it and is it important...

4.) is the minor tapping I hear when I rev it up probably an injector (i only tested the left front 3 for function and replaced a single bad BB 7.3 injector with an single AA 6.9 injector (they were brandy-new from stanadyne, at $30 a piece, not reman, I might change em all out soon) or is it a valve?

5.) Do the valves on these engines need adjusted?
