What are the most important maintenance checks for the Ford S-Max engine?

I just bought a Ford S-Max and I want to make sure I am taking good care of the engine. Are there any specific checks I should perform regularly to ensure optimal performance and longevity?

As a general rule, it is important to check the engine oil level and quality regularly, preferably every month or every 1,000 miles. Also, make sure to check the coolant level, the transmission fluid, and the brake fluid every 6 months. These fluids are crucial for the overall functioning of the engine.

Along with the fluids, make sure to check the timing belt at least once every year or every 10,000 miles. The timing belt is responsible for synchronizing the engine's camshaft and crankshaft and if it breaks, it can cause serious damage to the engine.

Lastly, don't forget to regularly inspect the spark plugs and replace them as needed. Spark plugs play a crucial role in the ignition process and bad or worn out spark plugs can lead to poor engine performance and even engine misfires.
