Hyundai Theta engine
This page carries a single unit: the G4KC 2.4L long block engine, the first-generation Theta four-cylinder rated 165 PS and 219–226 N.m at 4,250 rpm.
Its application list is short and specific, which makes it one of the easier codes to confirm from the vehicle side: Grandeur (TG) 2005–2008, Sonata (NF) 2004–2007, Optima (MG) 2005–2008 and Rondo 2007–2008. If your vehicle is later than those windows, you are almost certainly looking at the second-generation family instead.
That is the practical difference between the two pages. The G4KC is 2.4L at 165 PS; the later G4KJ is 2.4L at 201–203 PS and the G4KE 2.4L at 178–179 PS. Same displacement, different output, different application window — so the code stamped on the block settles it, not the litre figure on the tailgate.
Everything on this page is supplied New / 100% Tested. Confirm the code first, then check the application years against your own model year.
