Question about 1999 Oldsmobile Alero
Our daughter has a 1999 Olds Alero that she bought used about a year ago. Right before Christmas she noticed it would be losing coolant and occasionally overheat or run hotter than normal. At times it would run rough like it was missing too. After pouring over a repair manual her father decided it sounded like an intake manifold gasket. He replaced that and the resevoir cap and it didn't overheat or lose coolant for about a week but started to run rough again. He noticed that the new cap went on and came off quite hard. Now today our daughter called and said it overheated again but isn't running rough anymore. All she had done was put the old resevoir cap back on since it was easier to do. Please help! Is it possible that there's a fan problem? She said it was working when she checked. Can they go on and off due to a fuse problem or anything like that? Thank you! Pat Myers
In my experience it sounds like a head gasket problem it maybe leaking into the cylinders or could be a small leak from one of the hoses I would do a compression test just to make sure and then pressurize the entire system using radiator and coolant tester if pressure holds then its not a leak as far as the fans go just have the car running when it reaches the middle of the temp gauge it should come one if not you may need to run check on temp sensor or fan switch and fans them selves I would follow repair manual troubleshooting section on heating and cooling haynes or chiltons will do.
