Oldsmobile Aurora. Engine size = 4.0 litre V8.
Service engine, low engine coolant lights.
GM dealer replaced water pump, later replaced by-pass hoses beyond pump.
Question: Engine was losing water and noticed leaks. Repairs were done and re-done. After repairs
engine temp was way to hot. Bottom radiator hose burst. Replaced hose, still running hot. Replaced
thermostat, still running hot. Could not get to a repair shop, running hot,
mechanic said to bleed air
from block. Where and how? Tried threaded cap where radiator flush goes. I don't think this is right.
Help.

Answer:
Hello and welcome. The best way to bleed that aurora is to let it idle with the radiator cap off. Hold
the RPM's up to about 1,500 a couple of times. It takes a while to get the air out of those. What you
should do while it is running is keep an eye out for bubbles in the surge tank. These engines are
well known for having blown head gaskets, and that is a good signal.

Oldsmobile Aurora Overheats
I pressure checked system at 15psi for 15 min. Held steady. Drove for a couple of days, and was loosing
coolant. Found the radiator tank cracked on left side. (funny pressure test didn't find this). Replaced
radiator and still runs at 250 and pukes a little coolant out of the overflow. Though when I get done
driving 20 miles home from work, and check fluid it is just low, not blowing out
