1997 Oldsmobile Aurora 4.0 liter
Summary:
The Oldsmobile Auroras have a serious overheating problem caused by dex-cool
Faults:
I own a 1997 Oldsmobile Aurora. The car goes through a lot of brakes and has been running hot. I put a new radiator cap on it and it seemed to help for awhile. I had the radiator flushed out twice, because of the orange dex-cool antifreeze had it all clogged up. I finally had green antifreeze put back in it, but it continued to get too hot. The end finally came when it got so hot that it cracked a head last month.
General Comments:
The Oldsmobile Aurora has serious over-heating problems. I feel this is related to the junky orange antifreeze GM puts in them. I believe the Aurora should be added to the lawsuit against Dex-Cool.
Would you buy another car from this manufacturer? Yes

Well all the Auroras run hot, like when I'm in the city she runs hot, but when I get on the highway, it's in the middle.

I have no issue with Dexcool in my newer Vette. I make sure I only use distilled water proper ratio and never tap water. I certainly do not mix green or even use universal as well with Dexcool. I flush every 3 years and also remove my overflow bottle scrub thoroughly with simple green and rinse out. I also fill mine by removing the thermostat to avoid air pockets in the block. No issues with Dexcool..

All 1990s Auroras did in fact have terrible overheating trouble. But this was not due to the Dex Cool antifreeze. What caused this problem was the fact that in all 1995-99 Auroras, the head bolts were not large enough & the head gaskets were inadequate. These problems were addressed in time to make the 2001-03 Auroras immune to overheating due to poor design.

You should put some head gasket sealant in it. Trust me, it works!!!
