Are you sure that the thermostat is opening? If you let the car run to operating temp, does it get hotter and then suddenly cool down? If so, the thermostat is sticking and needs to be replaced. Put your hand on the radiator hose while the engine is warm. Use a shop towel that is wrapped in a way that it won't get caught in the fan to grip the hose. If the engine is at operating temp and you can't squeeze the hose much that is another sign that the thermostat is sticking. If the hose compresses, the coolant is moving through the thermostat.

A light come on with a box with arrow pointing down looks like waves what does it mean

This indicates a low level of coolant in the coolant bottle/resevoir..... this symbol represents the radiator or coolant system liquid level.

Warning comes on to warn of coolant level too low.

When the engine is cold...remove the cap and check level. Add 50/50 antifreeze/water to level indicated on the side of the coolant bottle or tank.

Reservoir Bottles/tanks are usually transparent and you can see the coolant level through the plastic.

When coolant topped off to correct level, lamp will go out need for scanner or shop to turn it off. It will come on as a 'self check' when you turn on the ignition and if level is okay will go out when engine starts.

Radiator warning light

Check your over flow canister.Sometimes if it is a little low it will make the light flash or come on.When the motor cools off Try topping it off with some coolant.If level is at or above operating level the the sensor itself might be sticking or you may have some air pockets in the system.You can also tap on the sensor which should be the only one on the radiator tank,(a two wire sensor) that may be sticking..If it still keeps coming on you may need to change that sensor..

1993 ecilpse Amber warning light lite on dash

This light represents the coolant level. If your coolant level sensor detects a lack of coolant, it will come on. I would advise filling your car to the proper level and also have a mechanic inspect your cooling system to find out why your coolant level dropped.

Good luck!

Coolant warning lights keeps coming on

Hello what i would do replace the fluid level run your car with the heater on hood up watch under your car for any fluid leaking if so try to determin about where it is coming from one of the hoses could have a small hole or a clamps not tight enough the right way is with a pressure checker but this is the best way for non proffesional rule out all hoses clamps and over flow bottle leaks before you start replacing parts goodluck please rate thanks
