Where does coolant go if not leaking?
Try and track down the smoke, but if it’s white, then it’s coolant. If you don’t have a visible leak underneath your engine, then you should take a look at your radiator cap or anywhere along the top or sides of your engine.
Can coolant evaporate without a leak?
However, with time, the Coolant flows within the engine and radiator; the chemical agents, after exposure to high temperature, lose their natural balance and get evaporated without any significant leakage. As the engine gets old, the Coolant evaporates more and more.
Will coolant leak when car is not running?
Coolant can leak from a vehicle that is not running because when the engine is off, the coolant is no longer under pressure and can pool in various places around the engine and can leak.
Why does coolant leak after engine is shut down?
Kinda. The system is pressurized as long as the engine is hot, so even after it is shut down there is some incentive for a leaking system to still leak, at least until the engine is cool. The question is only whether the leak is external or internal.. ie easy (ier) to spot, or not.
Can a coolant leak cause a car to overheat?
I cannot see the leak and the vehicle does not overheat. Hello, a coolant leak with no external leaks leads me to believe you might have an internal leak at the head gasket. The first thing to do would be to check the oil and see if it looks like chocolate milk.
What causes a diesel engine to overheat when there is no coolant?
If the coolant is too low this can allow pockets of air into cooling system. When air gets into the cooling system it will cause a reduction of coolant flow due to the presence of air bubbles. Air flow alone isn’t going to get the job done to keep engine temperatures constant.
What happens if you lose antifreeze with no apparent leak?
Losing Antifreeze With No Apparent Leak. Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.

Is there a coolant leak on a Duramax Diesel?
Currently, since December 2010 another supplement to the EGR cooler pressure tester adapter set, EN-48974-20, was shipped essential to dealers to diagnose EGR cooler engine coolant leaks on all 2010-2011 Duramax™ 6.6L engines equipped with multiple cooler EGR system.

What should I do if I lose coolant in my engine?
It is very important to note: If an investigation of loss of engine coolant leads to coolant found in one or multiple cylinders on the right bank, YOU MUST test the EGR cooler for leakage BEFORE attempting any engine repair. The cylinders affected with coolant will depend on which exhaust valves were open at the time of engine shutdown.
