Hyundai Repair: sizzling sound in my santa fe, spark plugs, radiator

Question
Hi.
Occassionally, I hear a sizzling sound out of my engine when I turn off the vehicle after driving.  My Santa Fe is a 2004, V6, 3.5L.  What could be causing this?  I purchased the vehicle about 1 1/2 months ago, new.  I do drive alot, and have already put over 4000 miles on it.  Thank you for your time.

Answer
Dear Isabel,
         It could be the radiator,it could be oil around the spark plugs, or there might be a small hole in the hose or radiator. But you might need to have it checked out.

                                   Thank You,
