If you have an AC equipped car - with the wild upper rad hose that tee's off to the expansion tank - most of them have a restrictor built into the hose near the expansion tank. This car i'm doing, it was clogged beyond rescue - so had to cut it off and splice in some more hose with a union.

Well I got under tonight and didn't see anything obviously leaking, I did notice on my lower radiator hose I put on last week was dripping a little so I tried refitting it a little better by pushing it up onto the connector and making sure the hose clamp was in the right place. I didn't see any leaks after that, I'm about to go down and top off the coolant and check for any more dribbles. On the other side of the radiator, it seemed to be leaking a little from the thermoswitch the fan plugs into. I tightened it a little bit but maybe it needs a new seal too.

While I was under there, I also noticed both my CV boots are torn, so it looks like I'll be replacing axles soon.
