There is no senor on the expansion tank. Check coolant level in the radiator. Or the sensor may be in the top off the thermostsat housing. Check the senor has power connected to it. If all correct remove senor and fill with coolant, it my have gatherd an air lock under the senor.

I drive a 1990 celica 185 gt4, it had an issue with blown head gasket ( pushing the water/coolent out expansion tank) got gasket done. head plained etc. i got car back from garage with head gasket done and...

im guessing that maybe your thermostat is sticking. im not sure what else would make your coolant rush out like that. if im right, then that would definitely make your car overheat at speed, but not at idle. that isassuming that the thermostat is at least partially open. if that doesnt fix the overheating, then u may want to consider checking the ignition timing for being too far advanced, or even the camshaft timing.

If the coolant was pink, it would be from transmission fluid leaking into the radiator. If you are not using orange coolant, it could be rust, or a chemical reaction.

2000 vw beetle 2.0 L, low level coolant light...engine mil code 1256

not the pump but air in the system or a broken wire to the coolant level sensor
that sensor at the top of the radiator tank has to be completely immersed in coolant or the circuit is broken and the light comes on
same effect id the wire to that sensor is broken in the insulation

My coolant is brown in the radiator and coolant tank

time to change the radiator fluid also flush out the system good the brown stuff is surface rust no big deal just have it flushed or do it yourself. make sure you have the proper coolent these days there are 2 main typs of coolent, to put it simply the green stuff and the orange stuff. my chevy truck takes the orange stuff. now you could be seeing old orange stuff and it may look brown to you so make sure you replace it with the correct fluid because they dont mix and you will do damage to your car. also if you find out you have orange coolent in your car you CANNOT MIX THIS WITH WATER.. it will also damage your car..if you have orange and decide to flush out the radiator it might be a good idea to have it done at a shop.. they will know how to do it correctly. if it takes green fluid its simple to flush and repalce it yourself because you CAN MIX WITH WATER. i hope this helps...

What is wronge when coolent light comes on a 1993 bmw 325is

If the coolant in the expansion tank is at the proper level, and you are still getting a coolant warning light, odds are that you have air in the cooling system causing surges in the expansion tank which make the float on the water level sensor go up and down and set the light.
If you have never replaced the expansion tank, it is most likely crumbling inside, letting air get sucked into the cooling system. Actually, if it was replaced once a decade ago, it may be due to be replaced again.
If you have had this car for a while, you know that keeping up with the plastic and rubber parts as they harden and crack on an older German car is a never-ending chore.
If the water level sensor has failed, you will have to disable it or cut the plug off the car and fabricate a plug connection for a new style sensor, because BMW no longer sells the water level sensor with this style plug.

Where is the low coolent sencer is there any way to test or clean

I have an 2002 Impala, which should be the same (What year is yours?). The coolant sensor is on the passenger side radiator tank, about 10 inches down from the radiator cap. on the engine side of the radiator.
I don't know how to test, but make sure your radiator is full, not just the plastic bottle.
I used to have the coolant light go on pretty regular. Under warranty, I think the dealer put in some fancy stop-leak. It hasn't been on since.

Symbol lit up

there can be a yellow light in the cluster that looks like a small radiator or box with waves inside of it to indicate water. This light means that the coolant level sensor has detected a low coolant level. Typically the expansion tanks inside of these cars will crack from heat and age. A simple diagnosis is to check your coolant level and top it off. Do not forget to bleed it by unscrewing the bleeder screw found on the upper radiator hose while filling up the reservoir found on the right hand side of the radiator. once the coolant has been filled, tighten the bleeder screw back down but be careful not to over tighten. and finally screw on the expansion tank cap. run the vehicle to operating temperature and use a flashlight to inspect the engine bay for leaks. If there is a leak, it will need to be repaired. possible leaks are a cracked expansion tank, leaking radiator hoses, or a leaking water pump or thermostat.

Coolant light

First check the coolant expansion tank and radiator for correct level. The radiator should be full (take the cap off when the engine is cold, doing this on a hot engine will cause hot coolant to spray out and possibly cause major burns). The expansion tank should be marked level-wise, either min-max, or min only, or max only. If the levels are right, your level sensor is probably bad. This sensor is located somewhere in the expansion tank.
