Start with your car's owners' manual.
It will have all the information you need like, how to check fluid levels, tyre pressures, fanbelts, how to change globes and all the various items that need checking on a regular basis.
You will need a few tools to carry out this work, but you don't need to spend thousands of dollars.
- A few screwdrivers (both phillips and plain).
- Some spanners (of varying sizes).
- A socket set.
- An oil filter remover (suitable for your car).
- Jack and axle stands.
