Please give me advice. Should I take car to the service or try to do myself? Hard job?

Thank's

do it yourself, its pretty easy, and it will be a learning experience

no biggie get a haynes manual and roll up your sleeves

It is actually easy. Just annoying to get the belt off. There is a tensioner pulley that has to be turned clockwise to release the belt.

big stick, take it and slid it down the side of the car and then push the tensior down, or you can do it the right way and take the top motor mount off and drop the engine.

but back to the main subject, you "can" do it yourself, but depending on your motor and miles you might as well replace you timming chain while your down there
