Coolant finishes 3-4days

ANSWER : Hi there. For the coolant light to go out, you would need to have the coolant between the low line and the full line for the light to go out. If the coolant is low and keeps on being low, then look for any signs of coolant leaks. You may have to use a coolant pressure tester to pressurize the reservoir to allow the leak to be found.

If you need further assistance with the coolant being low and the warning light being on, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hey there:

It’s common for many mechanics to make the mistake of mis-diagnosing the cause of an overheating situation; especially when they assume it’s a thermostat issue. The problem could be caused by a blockage in the coolant tubes running from the radiator to the overflow tank and back to the radiator. However, it also may be due to air trapped in the coolant lines. I think a good idea would be to contact a different ASE certified mechanic, such as one from YourMechanic, and have them complete a coolant flush, which should remove any blockages in the coolant tubes and may solve your problem.

ANSWER : Check the transmission fluid. If all testing eliminates the head gasket, cracked cylinder head, etc, it may be a cracked radiator.Transmission fluid is sent forward to the radiator to be cooled. Ir runs into what is typically called the "side tanks" of the radiator. So the transmission fluid and coolant are both flowing through the radiator and kept apart just as the engine oil and coolant are kept apart in the engine by the head gasket, coolant and oil passages, etc. If the tank in the radiator is cracked internally, transmission fluid may actually be forced into the coolant as transmission fluid is under higher pressure than the coolant. Short of a cracked head gasket, cylinder head, or engine block, it’s really the only other source of any type of oil getting into the coolant unless the vehicle is equipped with an engine oil cooler as well.

ANSWER : Hi there. The milky engine oil is caused when the coolant from the cooling system gets into the engine oil. There are two ways that the coolant can mix with the oil on your vehicle. The first way is through the intake manifold as the gasket may crack causing the coolant to drain into the valley area making the coolant mix with the engine oil. However, the engine will not overheat quickly when this happens. The second way for the coolant to mix with the engine oil is through a burned head gasket. To verify that the head gasket is burned, get a block tester from your local parts store and set up the tool by putting the blue chemical in the tube and putting on the plunger on the end. Then remove the reservoir cap or radiator cap (take precautions of the coolant) and start the engine. Take the tool and place it over the inlet area to the reservoir or radiator. When steam starts to form in the area, use the plunger and suck in the steam into the tool. If there is any hydro carbons (raw unburnt fuel) in the cooling system, then the blue chemical will turn to a yellow or greenish color. If the color changes, the head gasket is burned and needs replaced. If the chemical does not change color, then the head gasket is good and there could be a leak on the intake gasket. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your engine overheating issue.

ANSWER : Hello. The most common cause of a random coolant loss on this vehicle is a leaking intake manifold gasket. It commonly starts leaking coolant into the engine, which will be burnt off or will leak externally. I typically do a pressure test and a dye test on the system first to see if I can locate an external leak. If nothing is found, then I do a block test to make sure that there is not a head gasket issue. If nothing shows up there, then I replace the intake gaskets. If you need to have this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the coolant leak and replace the intake gaskets if necessary.

ANSWER : Not knowing which exact type of coolant was used to refill the system after the block heater install, I would consider flushing the cooling system and refilling with the correct coolant. Years ago, we just had "green coolant that went into every car. In recent years, different manufacturers call for different coolants. There are a number of different metals in contact with the coolant nowadays. The engine block can be cast iron, the cylinder heads can be aluminum. The head gasket may have steel rings surrounding each cylinder bore. The coolant has to be able to interact with all the different metals and not cause additional corrosion. Mixing different coolants can cause some issues. Sometimes the mixture can cause gelling and clog smaller passages in the radiator and heater core. They can also interact poorly with the different metals when mixed. I’ve replaced a few heater cores because they were so badly clogged from mixed coolant. Considering these things and the climate you are taking the vehicle to, a cooling system flush is definitely a good idea.

ANSWER : Hi there. Quite frequently when red and green coolant is mixed and inside the coolant tubes for a long time, it can cause excessive wear of the coolant tubes. The ’glitter’ you see may be excessive debris that may have worn off the coolant hoses. Whether or not you can continue to run with this coolant; it shouldn’t be a problem. However, I would recommend that the next time you flush your coolant, that you also replace the coolant hoses and tubes.

ANSWER : Hi. Unless you are having to repeatedly refill the coolant system – which indicates a different problem, the false "low coolant" issue may simply be a failed sensor in the coolant recovery tank. It is not recognizing that there is adequate fluid in the tank. The scenario you describe where the car will not start after being driven, then parked suggests a "heat-soak" issue for an electrical component (crank/cam position sensor, starter solenoid, neutral safety switch, etc.). If you would like to have this looked at, a certified technician from YourMechanic can diagnose the starting issue and follow through with repairs.
