What happens when coolant leaks from an engine?
When coolant leaks, air will take its place. Because air is compressible, the boiling point will lower, allowing some of the coolant to flash into steam. Air and steam are great insulators and will prevent the cooling system from expelling excess heat.
How to check for a mystery coolant leak?
Mystery Coolant Leak 1 Get a radiator pressure tester and check that the system will hold pressure. Get some soapy water and brush on all… 2 Do a cylinder compression test. 3 Use 50/50 mix of MB fluid, sounds like you have mostly water in sys. that would drastically effect the boiling point… More …
When to take your car to the doctor for coolant leak?
If the block is cracked or the cylinder head is warped, your engine needs to be taken to an auto professional for major repairs. Stop-leak products are meant for hairline imperfections and minuscule cracks, not the kind of leaks that result in a puddle beneath your vehicle or a coolant smell permeating your car.
What happens when you put pressure on coolant?
Some call it anti-freeze, but that’s just a side-effect of engine coolant’s function. Adding pressure further increases the boiling point, up to 267 °F (130 °C) for a 50/50 blend. A new engine is usually able to maintain its coolant in the radiator, hoses, and coolant passages.

Can a worn radiator cap cause coolant to leak?
A worn, weak, or leaking radiator cap will not hold pressure, lowering the boiling point and allowing coolant to boil out. It may also allow coolant to leak externally. Luckily, this is a quick and cheap fix. Just wait for the engine to cool, refill the cooling system, and install a new radiator cap.
