This video shows where the coolant leak on this Mazda CX-9. Due to casting failure either cylinder head or the cylinder block.

Mazda Coolant leak vehicle range as follows.
2019 to 2020 CX-5 Sky active 2.5L turbo engine.
2016 to 2020 CX-9 Sky active 2.5L turbo engine.
2018 to 2020 Mazda 6 Sky active 2.5L turbo engine.

You will easily find this once you carry out cooling system pressure test.

When it comes to the potential damages caused by a coolant leak in the engine, there are several important considerations. Coolant plays a crucial role in regulating the operating temperature of the engine. When there's a leak, the engine can overheat, leading to a range of problems, including:

1. Engine damage: Overheating can cause the engine components to expand beyond their design limits, leading to warping, cracking, or other forms of damage to the engine block, cylinder head, or gaskets.

2. Reduced lubrication: The excess heat from an overheating engine can also cause the oil to break down more quickly, reducing its effectiveness as a lubricant and potentially leading to increased wear on engine components.

3. Blown head gasket: If the engine overheats severely, it can cause the head gasket to fail, leading to a loss of compression, mixing of coolant and oil, and potential damage to the engine internals.

4. Electrical system damage: Coolant leaks can also affect electrical components if the coolant comes into contact with wiring or connectors, potentially causing short circuits or other electrical issues.

Overall, a coolant leak in a Mazda VRX-9 can lead to significant and costly engine damage if not addressed promptly. It's important to identify and repair coolant leaks as soon as possible to prevent these potential issues.
