The engine light needs to be scanned with a scan tool to pull a code, with that code you can start to diagnose, check your gas cap, make sure its tight, other than that you need to get it scanned before we can help you further

The local high school auto shop recently replaced the radiator in my 2006 Yukon and did not connect the oil lines correctly. The oil leaked out and the engine stopped.

A lot depends on how long the engine ran without oil. If the starter will still crank it, you might be lucky. If the engine has a lot of miles on it, it might be best to overhaul it, since rings and crankshaft bearings suffer the most .

One cylinder piston has seized. can it be repaired? 2006 Acura TL (manual) V6

Bad news is it can be fixed but requires complete overhaul I'll bet. Swapping in used engine might be better, or crate engine if price is not important.

Yukon XL was first showing Reduced Engine Power, then Oil Gauge quit working, now car is running hot

Might help, disconnect negative terminal from battery for 10 minutes, if the compute is getting weird readings this will reset it and maybe help.

Oil light comes on,low oil pressure, message says shut engine off now

HI, could be failure of the engine oil pump.. if you are still running around in the vehicle it might be the sensor on the engine block that is faulty, cause without oil pressure your engine will seize up and that's expensive.what about a good oil change and a nice new oil filter, could do wonders ?.good luck.

Service engine light staying on

Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.
