Question about Cars & Trucks
Cold Start, drove 15 miles, shut off engine and exited to find antifreeze pouring out. End of day, cold start, added 1 lt. water. Drove 6 miles, temp. spiked. With engine running, added 2 lts. water, fan shut off temp. came back to normal. Turned defrost on high and drove 12 miles, stopping and shutting off engine once to pick up kids, no leakage, made it home. Outside temp was 30 deg. Coolant Level Low has been coming on at start (and clearing) for some time now. It became the 'boy crying wolf', as the level was always ok.
So you had it at several repair shop that can't find anything
or don't believ your loosing coolant
Sorry I can't guess I would need the car to check & test
Some major issue like a Head Gasket ??

SOURCE: engine running to cool
Replace the thermostat. If thermo is stuck open, coolant only heats up when there is no flow over radiator(idle) and then cools down when driving. Also, check coolant level, same response as stuck thermo.

Your Buick is a 3.8 liter, and probably the best engine ever built. But as all good things it has a few flaws.
It is a aluminum block, that doesn't do well at all with heat, yet at -03 f. I would be more concerned with it freezing. Again a problem with anything aluminum.
The problem I have found is that the heads will crack and the dieseling you describe is common of a 3.8 with a cracked head. I would pull the spark plugs, if it is dieseling it has to have water on one of the cylinders. Pulling the spark plugs will tell wich one. and also check for faulty or blown freeze plugs in the block. They may just be pushed out a little.

waterpump houseing/shaft seal is on the way out hence the water/coolant, running along the block. when hot the seal does so, when cold and depressurising seal doesnt.

are you sure the cooling fans are working?
Is the coolant temp gauge telling the truth?
have you lifted the hood and heard the coolant bubbling into the overflow?
Or heard the tinging sound of a red hot engine?
If he did a liquid test with the dye,and it changed colors it should have changed very fast,
Another thing to think about if he was to take the fan belt off,and pull the thermostat housing off,and removed the thermostat,Now pour coolant into the thermostat hole to almost the top,Now start the car and see which side the bubbles come from,left or right,that will be the gasket that is leaking not both.

the symptoms are that you have a burnt head gasket, its consuming the water into the cylinders and at the same time it builds combustion pressure in the cooling system causing it to overheat, and when it overheats it makes the oil loose viscosity so you loose oil pressure, i recommend not driving the car any more and the first solution is to replace the burnt gasket, and change your oil, go to a local shop and only do these they probably tell you the engine is worn but the problem is what i told you above, make them replace the thermostat unit yes to be sure good luck
