I have two Hyundai's and they came with a limited lifetime warranty. I would take them to the dealer for any work. If the car does not have a warranty any longer, a realiable garage that you trust is the best place, assuming you can not or do not wish to do the work yourself.
Personally, if not warranty, I do all maintenance myself. This requires the correct tools, but ensures the job is done correctly and as inexpensively as possible.
Yes, there is an engine diagram for a 2003 Hyundai Elantra. It is found in the car maintenance manual and in its repair manual.
Expensive, especially if it's getting older! This is because it's a foreign car, and foreign cars are always more expensive to repair.
You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
get time machine out of garage, travel to the year 2055, get in car, and take it to the dealer.
