To be absolutely certain, I recommend:
* Checking your owner's manual: This is the best source of information for your specific vehicle. It will have diagrams and instructions.
* Using a visual search online: Search for "[your Santa Fe year] 3.3L engine oil filter location" on YouTube or Google Images. You'll likely find videos or photos showing exactly where it is.
Don't attempt an oil change without consulting your owner's manual. It contains important information about the type of oil and filter to use.
