There should be a bleeder valve on the thermostat housing open bleeder until coolant comes out with no air and tighten top off coolant to mark on coolant jug

There is no trick to adding coolant....just open the cap on the overflow...and add! And remember....you could always have a faulty low coolant sensor!

RE: SOLUTION #3 The Orange Coolant is Dex Coolant. My '96 Cavalier Specifically says to use Dex Cool in the Radiator. I'd not just switch to the green coolant, but look at the specifications for your car in your car manual.

When bleeding remove cap to the filler bottle with motor off, loosen the small bleeder located on the metal tube on the right side of engine. keep pouring 50/50 antifreeze into filler bottel until fluid suck's from bleeder. if this does not help then pull your plugs one at a time and see if any of the plugs are super clean. if a plug looks new i mean real shinney then your head gasket is shot. now when you bleed it may take some time for the fluid to start pissing so be patient and keep bottel full. i just went threw this today, changed water pump and the thermostat. also all mechanics i talked to said get rid of the orange anti freeze and put in the prestone green. the orange eats up all the gaskets. good luck

The mechanics who told you to replace the orange coolant with the green were mistaken, poorly educated, or to cheap to stock the propper fluid (yes dex-cool does cost a little more then the "green" stuff). Your going to be hurting your engine in the long run and lowering its lifespan by using impropper fluids. If you want your car to last NEVER cheap out and cut corners when it comes to fluids. No exceptions. Higher quality fluids are only slightly more expensive and make a huge difference in the lifespan and general wear and tear of your vehicle. It's the little things that really add up to a long lasting vehicle. And its a no brainer when the manufacture is telling you that your car MUST have a certain type of fluid.


If your dash light is going off for your coolant. There are a few things that could be going on.

1) Your coolant is low

2) Your coolant sensor is damaged (common to happen around the 10 year mark)

3) Your thermostat need replacing (very cheap and easy repair you can probalby do yourself in most cases)

3) Your water pump is going out. The pump is designed to bleed fluid as the bearings are wearing out to alert you its time to replace the coolant pump before it goes out completely. DO NOT PROCRASTINATE with this repair or you can risk severe engine damage. If you see smoke pull over immediately and do not attempt to drive your car further until it is diagnosed and repaired. You will destory your engine otherwise and turn a $100-200 repair into a $3000-4000 repair.

have you replaced radiator cap with the proper pressure cap? if so you may have a head gasket letting some compression into cooling system building too much pressure so the cap is bleeding it off into resevoir

Low Coolant Light Staying on


This car has sensors on it. If the coolant tank is full and the system is working properly, then one of the sensors is bad.

Have the cooling system presure tested to make sure you have no leaks. If test is good, then look to the sensors.

GM has different systems for each car depending on configuration, so it is hard to point to the one that may be bad.
