Why does my car have no apparent leaks?
You don’t see a leak because it’s not actually a leak, but am overflow while the engine is running only. There is another way this fluid loss can occur and that’s with a head gasket leaking cooling fluid into a cylinder. Not thermostat which only regulates the engine temperature. Your problem is hopefully simple.
What to do if your car has a leak?
Driving with such a leak WILL destroy it. Get the car to a qualified technician and have him check the coolant for absorbed exhaust gases. This will determine if coolant is getting in to the engine. You will not be able to determine anything by looking at the tailpipe exhaust.
What should you do when your car is losing coolant but no leak?
Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?
How can you tell if your car has a water leak?
The radiator coolant level will drop perceptibly, while the oil level in the crankcase will rise. At this point, signs of exterior water leakage will show. Chris Stevenson has been writing since 1988.

Why is there no oil leak in my car?
If you confirm that the PCV valve doesn’t have a problem and you ensured no internal leak inside the engine, the problem could be related to internal engine failure. There are different engine components, and many of them could be the culprit for oil overconsumption.
What does it mean if your car is losing coolant but no leak?
However, you may breathe easy if the mechanic does not find any trace of exhaust gases in the coolant. It means that the liquid has not reached the engine yet. The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid.
What causes a car to start but not keep running?
The engine requires the right amount of air and fuel to mix together for ignition. If there is a fuel leak somewhere, then the correct amount of fuel may not make it to the combustion chamber. This might be enough to allow the engine to start, but not keep running.
What causes a car to start and then die?
But if there is a fuel leak somewhere, then the proper amount of fuel won’t be able to make it to the combustion chamber. This might cause the engine to still start, but it won’t be able to keep it running. That is why it will die almost immediately after it starts.
What causes a car to run lean at idle?
If the root cause is an electrical problem within the idle air control valve itself, you will likely have to replace the IAC. A vacuum leak is a hole in a vehicle’s air intake system behind the mass air flow (MAF) sensor that allows unmetered air into the engine. This throws off the expected air fuel ratio and causes the vehicle to run lean.
What causes a car to run with a vacuum leak?
Normally a car will still run with minor vacuum leaks, but if the leak is severe, the fuel injectors may not be able to keep up with all the extra unmetered air in the system for a proper burn in the combustion chamber.
