MY LOW COOLANT LIGHT ON MY 2001 OLDSMOBILE ALERO WONT GO OFF AND CAR IS OVER HEATING.. I CHECKED RADIATOR FLOW TO SEE IF THERE WAS ANY THING BLOCKING FLOW BUT THERE WAS NOTHING SO I CHECKED THE THERMOSTAT AND IT IS GOOD TOO.. RUNNING OUT OF OPTIONS ANY IDEAS.. AND DOES A CAR NEED TO HAVE ANTIFREEZE IN IT IN THE SUMMER TIME???
If your coolant level is full the low coolant switch is probably faulty they are normaly just a float & the float might be stuck. & Coolant should be used all year round as it is not just anti freeze but is (Anti freeze, Anti boil, & acidity, alkalinity regulator.) It changes the freezing/boiling point (water freeze at o degrees centegrade & boil at 100 degrees but with glycol it changes this depending on what % glycol there is in the system. The acid/alkaline regulator is corosion inhibitor to prevent parts being eaten from the inside out (radiators, heater cores, welsh plugs etc..)

When you say not leaking antifreeze has your coolant level gone down at all? and is it that you have seen no leaks where you park it? What worries me is you can smell it when warming up, have you felt the interior floors to see if damp and do you get any condensation if put blower onto screen, if so then heater matrix is leaking if not could be down to headgasket and/or cylinder head leak.

You must always check the coolant hot, expansion will cause a big change in level, how low was it? top it off hot and then drive a few days and recheck the level, I don't think you have an issue here.

below radioator or side low should b plastic plug which u can unscrew & emty the fluid
SOURCE: Where is the radiator drain plug for a oldsmobile
The radiator drain plug is on the lower left front (drivers side) of the radiator. To access it you may have to remove the front air dam. It is a white plastic plug and requires a Torx socket to loosen (sorry but not sure of the exact size of the Torx socket). Insert Torx and turn counter clockwise a half turn. Pull the plug out using a pliers until fluid begins to drain. Be careful because this is a plastic plug and may break easily. When fluid is finished draining simply push the plug in and turn clockwise half a turn with the Torx socket to secure.

I have an 02 olds alero (142000) the radiator fans are not working, therefore overheating. I have replaced the thermostat, water pump, coolant, what causes the fans not to work?
