Thanks for watching this Mark's reviews and Tutorials video. Mark is not a trained mechanic. Just a car guy that loves to drive and work on cars. What I do here may not work on your car and I am not intending to give professional advice for you to work on your car. But if you do know a bit about cars then hopefully watching these videos will help you to sort out what is going on with your car. Mark is not liable or responsible for any damage you do or things that happen to your car or yourself.
Cars are complex and dangerous things and not only can you be hurt working on them but you can also do serious and expensive damage to your car.
Cars should be worked on by qualified people, don't over reach.
