I had the same problem with a '96 Ford Taurus SHO. There was a level sensor on the radiator overflow reservoir that failed. I could not locate a replacement anywhere in the country, in dealerships or junk yards. I sold the car shortly thereafter, which is too bad, I dearly loved that car. I would think you would be more lucky if this is your problem. Check the overflow bottle and sensor for a problem and proceed accordingly.

SOURCE: ENGINE LIGHT COMES ON WHILE DRIVING MERCEDES BENZ

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

A flashing check engine light is an indication of a severe misfire or problem that is likely to harm your engine. Immediate diagnosis and service is needed.

Some specific causes for the light to be on are:

Gas cap left off, not tightened, not installed correctly, or needs to be replaced

02 sensor

Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups

At start up for a bulb check - Should not stay on

Problem in the emission system, including clogged exhaust or the catalytic converter not functioning properly

Dirty/clogged air filter

Dirty MAF sensor

SOURCE: 2004 mercedes clk reads coolant visit workshop.

It could be either the left front fuse and relay box,left front sam or the engine control module. Basically it's in a safety mode right now because the engine control module is not getting the coolant temp. The early clk's had this problem when they came out with the new body style. Was a common problem for awhile.

How to I get the, "low coolant", light to turn off on my 2001 Chevy lumina


have the coolant sensor checked and check the wire to it
they work by having a continuous power supply through the sensor through the coolant to earth to keep the light off
any break in that wire of sensor results as a low coolant because the power can no longer earth out and so the light comes on

My low coolant light keeps coming on the coolant is full and doesnt over heat would that be a coolant level sensor


Hello: Yes, you are correct, the sensor is normally located on the passenger side of the radiator tank. You only have to drain the cooling system down below the sensor. On some models the level sensor is in the coolant overflow tank.

I have a 2000 silhouette. the coolant level low light keeps coming on even though coolant has been added. after about 10 minutes of idling the temp rises to just below h.but temp is fine while driving....


Bleed the air out of the coolant system,and add more coolant,to radiator,and reservoir,and make sure the cooling fans are coming on,if the low coolant light stays on,remove the low coolant light sensor,and clean it off,it is located on passengers side in the radiator,it has a wire clip you have to remove,and dont loose it,after cleaning it,put the clip back on the sensor,and push the sensor back in the hole.

Need to replace coolant sensor were is it at my coolant light stays on I reset it but it keeps coming back on so I think it is the sensor.


Follow the top radiator hose to where it meets the engine, that will be the thermostat housing, it will be on that or nearby.

The low coolant level light keeps coming on on my 1995 camaro z28. I have replaced the radiator, thermostat, and coolant level sensor. That I know of, there are no leaks. What do I do?


Replace the low coolant sensor right side if radiator. When you replaced the radiator
they may have installed the old sensor.

I had the same problem.
