Hello! I would like to know which preventive cares and how often showed I check them up as for keeping a healthy car. I don't know much of cars and it's my first car, my dad have it to me and want to take care of it since it reminds me of him. I live in south America, Santa Cruz Bolivia.

I'm owner of a NISSAN pathfinder 2006, American model, 94.000 mileage and automatic transmission.

Currently according to a local mechanic, I'm facing trouble on the left side tray bushing and cap. Other thing it's detected it's a small leak of motor liquid because of a worn out engine gasket. This used to be my dad's car.

And last but not least which other recommendations could you give a first car owner to keep a healthy car.

Thanks in advanced
