A friendly driver stopped by, then got some water, poured it into the radiator and it all came out at the bottom.
This EA82 engine was just installed a few days ago and the the car has been driven for about 200 miles since then.
My question is, what's the likely cause of that overheating? Can a radiator burst? A hose that went bad? All hoses are new. Also, I have another radiator from a parts car - actually just the rear row, the bigger one.
Could it have damaged the heads? I know that the ones installed on there did not have any cracks. How can I verify that there is no permanent damage? Pull compression? Anything else? The car is currently at a shop a few hours away, so I cannot take a look at it and my anxiety level is pretty high. Main thing, I don't want to damage the engine which I just got and which ran beautifully.

"all the water came out the bottom"
sond like the radiator went crap.. soob radiators are not exactly the world champions of cooling anyway..
only sure way of checking for permanent damage is to pull the heads off and look them over, maybe have them magnafluxed

I never got a chance to look at it (it is out of town) but the shop said it is not the radiator. Seems like incompetent install, the people who installed the engine apparently did not properly tighten the metal line which goes from the radiator to engine. It is that silver looking metal line.
They said it idles fine, but I will make the shop which did the install pull heads and check them. Chances are, they need replacement. <sigh>

This last winter I pulled apart an EA82 that had been over heated, died on the HWY, dude poped the clutch at 65 MPH. He kept driving untill it died again. He pulls over and waits for the temp guage to go down to about half. Starts it up again and drives home (another 10 miles).
The next day he calls me to come 'take a look at whats wrong'. He trys to start it and coolant starst SQUIRTING up rythmicly from everywhere and it sounds like a bong with all the bubbling in the overflow tank.
Well when we pulled it all apart there really wasnt HUGE amounts of damage that was expected. The lower end held together fine. Minimal scoring on the cylinder walls, heads had no visible cracks, valve train looked ok.
Point is I dont think in 5 minutes of driving overheated that there is any irrepairable damage done. You werent mixing oil and coolant (which is HORRIBLE on the power train!) and as long as you had good oil pressure I think you still have a reliable subaru on your hands.

If that's what it is, it shoulda been tested before the original shop let it out their door. I don't think I'd even want to let them put a wrench on my engine again, even to check the heads....

It is really aggravating to helplessly watch these developments from afar. It was out of town, that far away.
I should have it back in a few hours. I will do a compression check first of all, if the compression comes up as 170 PSI in all cylinders, should I assume that the heads are not cracked?

Subarus are rough and tough and I'm sure your engine is fine

The fix was - some "mechanic" charged $115 to "find why overheated and reconnect cooling line". Including $2 for coolant. No parts replaced. Sounds excessive? The main driver of the car thinks they got a great deal.
I usually do't' let "mechanics" touch my vehicles but this was beyond my control.

Sounds like a typical invoice. A bit on the high side but what did they charge for labor? Then theres good old uncle sam stepping in for his share (read: taxes) While they didnt necesarily get ripped off its nothing I (or you I'm sure) would pay to have the waterpump tube fixed.
I bet you see another load of RTV like you found before =P

Passenger's side: 125 and 115.
Driver's side: 75 and 90.
Sounds like the heads need to come off and re-installed. It should be way higher than this. What's the normal compression? 175? The last time I pulled compression on this engine, I got 175 on the driver's side. Before the engine got installed.
Another question: There is a hose that's disconnected and I cannot figure out where it should be plugged in. It is a T to a hose running from the transmission to the engine block. That T is right near the EGR valve, slightly ahead of it. It about 1/4" in diameter and it is sucking air in. Without it, the car seems to idle poorly.
