Coolant only disappears one way. A leak. But the worst case is when it leaks into the engine. Gives you a chocolate shake for oil. Coolant doesn't dissipate like boiling water because it's sealed and why it overruns into the reservoir. As it cools **** out of the reservoir. If coolant level is lowering and causing overheating it's leaking. Just hope it's not into the motor.

Hi, radiator sealant is usually only good for sealing small leaks, did you top up the coolant level? Can you see where the coolant is leaking from? What vehicle is it?

I have noticed a whitish /milkish appearance from the engine oil on the oil dip stick what is the meaning of this milkish


Hi.

Do a compression test and look for symptoms of head gasket problems. If the leak is internal, then the most common cause is a worn head gasket. Water (or coolant) leaks internally through the head gasket reaching the cylinders where it gets vaporized. Symptoms are coolant fluid level going down (with no external leaks), bad performance, loss of compression, overheating, white smoke from exhaust because of vaporized coolant, traces of fuel in coolant reservoir etc.

If there is no head gasket problem and there is no overheating, then the leak is external. Check pump, radiator and coolant lines.

Regards.

Overheating


OVERHEATING CAN BE CAUSE BY MANY THINGS LIKE FAULTY THERMOSTAT AND FAULTY RADIATOR PRESSURE CAP,TOO MUCH WATER IN COOLANT SYSTEM NEED 50 / 50 WATER AND ANTIFREEZE.LOOK FOR WATER PUMP WEEP HOLE LEAK, IF COOLANT LEAKING OUT WEEP HOLE WATER PUMP BAD NEED REPLACING.CHECK FOR LOW COOLANT LEVEL, YOUR RADIATOR OVERFLOW JUG SHOULD HAVE COOLANT AT THE FULL COLD MARK IF NOT KEEP ADDING COOLANT INTO COOLANT OVERFLOW JUG UNTIL COOLANT STOP DROPPING AND FULL COLD MARK, IF OVERFLOW COOLANT JUG WAS EMPTY RADIATOR IS LOW ON COOLANT.WHICH CAUSE AIR IN COOLANT SYSTEM KEEPING THE ENGINE COOLANT TEMPERATURE SENSOR FROM BEING SUBMERGE IN HOT COOLANT WHICH TURN ON THE COOLANT FANS.WHEN ENGINE COOLANT TEMPERATURE GET CERTAIN SET TEMPERATURE LIKE 190 DEGREES THE PCM AND COOLANT SENSOR WILL TURN ON COOLANT FANS, IF VECHICLE OVERHEATING COOLANT FANS NOT WORKING EITHER YOU HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR CHECK COOLANT FANS FUSE AND RELAYS. YOU CAN CODE SCAN CAR TO SEE IF YOU HAVE FAULTY PCM, FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR FAULTY COOLANT FAN RELAY.IF COOLANT FAN AND ENGINE COOLANT TEMPERATURE SENSOR OKAY,YOU HAVE CORRECT COOLANT LEVEL IN COOLANT SYSTEM, THERMOSTAT AND RADIATOR PRESSURE CAP BEEN REPLACED, YOU COULD HAVE BLOWN HEAD GASKET CHECK ENGINE OIL LOOKS LIKE MILK SHAKE HEAD GASKET BLOWED ALSO WHEN HEAD GASKET BLOWED YOU CAN DRIVE CAR SHORT DISTANCE START OVERHEATING AND YOU LOOSE ENGINE POWER SUSPECT BLOWED HEAD GASKET.

My daewoo is leaking waterand overheating


Thanks for choosing FixYa and welcome. You need to find the leak. If it is coolant leaking, this is your problem. If it is inside the engine, it will be a hard fix. If not, check all the hoses. Check your level of coolant fluid. If it is a slow leak, might be able to add coolant so often to keep it cool. Make sure your fans and radiator are working. A sticking or bad thermostat is the most common issue for overheating, followed by the water pump, valve, and impeller. If it is a bad leak, it will cause overheating. If you are low on coolant, same thing. If you have a question, let me know.

1986 4000S OVERHEATING REPLACED THERMOSTAT/ NO APPARENT LEAKS FLUID LEVEL GOOD WHAT ELSE CAN I CHECK?


Time to replace the radiator. Over time, the water added to the coolant system will have the calcium bond with the aluminum in the radiator at the narrowest points, restricting flow. The thermostat compensates until the cooling capacity of the radiator is reached. Changing the thermostat does nothing. The coolant needs to be replaced with new coolant which has the corrosion inhibitors that prevent the formation of these deposits.

Engine heat keeps going up even after refilling coolant.


are you leaking coolant ? or you were just low and added fluid to it ? if your car is full of coolant and still overheating change the thermostat first its the cheapest and easiest starting point.

If that does not work i would replaced the coolant temp sensor pretty cheap to that tells the ecu when to turn of your electric fan assuming you have a electric fan.

if you have a clutch fan aka belt driven you may need to replace the fan clutch its basiclly a unit that expands and contrancts a spring to turn fan off and on.

if none of the above work you probably have a faulty water pump even though its not leaking the propeller blade inside is likely rusted and limited functionallity


if this helps you please give me a good rating

90 legacy, started overheating but was blowing cool air out of the heater even as the needle was pegged. Some fluid in reservoir, top radiator hose felt like it was under a lot of pressure.


Two things would cause this

There is a slow leak and the radiator is low on fluid

Let the vehicle cool down completely and then check the level in the radiator. I bet its pretty low. Top off the radiator with a 50/50 mix of coolant and water. start the vehicle and let it warm up with out the radiator cap on. Keep adding fluid as necessary. While waiting for it to warm up check around for any abvious coolant leaks. Things like hoses, radiator seams, water pump, water inlet/outlet gaskets. If no leaks are found it may be necessary to pressure test the cooling system and even then it might be a slow leak that only occurs when the vehicle is cold.

If the radiator is full than I would suspect that water pump is no longer working or creating enough flow. If the thermostat where stuck you would still get heat. If the water pump is not circulating coolant than you would get no heat and the car would overheat.

My radiator (1996 Ford Explorer) is leaking at the bottom. No problem with heating or cooling or running hot. Just steady drip


You can have it repaired at a radiator shop, or replaced with a new one. Are you sure it's the radiator that's leaking, sometimes it's the water pump or a hose that drips down onto the radiator. It can be difficult to locate due to air circulation of the fan and driving which spreads the leaking fluid around. I assume u top off the coolant often, since u say there are no issues w/ it overheating or running hot. If this is the case, the leak will eventually get worse, and adding coolant constantly gets expensive. Good luck, let me know what u decide to do, or if u have any other questions. Curt
