I have a 94 Achiva S. The coolant light came on in my car a few times, I checked the level of coolant and filled it when necessary. Recently, the water pump died causing the car to over heat. I would suggest getting coolant system looked at. The test can be done for about $30 and may save you a lot in the long run.

I also have a 1994 Oldsmobile Achieva S. It is a very good car. I have had it for 2 years, and only had to replace brakes, starter. It's a 3.1 V6, very quick car, beat an 89 Acura Legend, and a few Honda Accords.

Would like to know how much horse power it has. If any one knows, email me doughfriend1960@charter.net

Things I've replaced on it to make it run better, didn't need to replace any of it, but did anyway:

Radiator, oxygen sensor, oil pump, exhaust, coolant temp sensor, coolant sensor, intake, temp sensor, thermostat.

If anybody has any coolant trouble, replace your thermostat and/or temp sensor.

The Achieva seems to have problems with its gauges. I have replaced all of this stuff, and sometimes have coolant light, engine light, oil light to come on, but there's nothing wrong with it. I would say that is what is wrong with a lot of your cars. Just keep checking fluids..

I have a '94 Achieva. It has nearly 300,000 kms on the motor and is still running great. Awesome power for a 3.1 litre. My check engine light and check gas lights come on often. If it is just the check engine, it is likely the 02 sensor. Check fuel may be the fuel filter needing changed and if you don't change it, it may cost you around $300 for a new fuel pump. I had my car checked out and changed the fuel filter, but the light still comes on. Mechanics say that it is likely that it is the module for the gauges/instruments.I recommend changing the fuel filter once a year.
