I was told by the main driver of this 92 Loyale that it overheated. The vehicle pulled over, shut the engine when "smoke" was coming from under the hood. I also found out that the vehicle was driven with the temp gauge in the red for at least 3-4 minutes and then it idled for another minute.
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.
