Hi, have a 04 sonata with the 2.4dohc ,the wife drives it to her work 75miles one way 90% highway driveing ,it has 57k on it now thats about 3000 a month , Runs great change oil each month an just did a plug change on it ( ngk's ) ,any way at what miles should I replace the timeing belt? We live in Arizona an wondered if maybe the heat would have a effect on it also ? Thanks for any advice , Slimone

 

I have a 98 Sonata, bought it used with 66k miles. 1 year later with 74k miles the timing belt broke while I was on a trip. Cost $2500 to replace the engine with a used one. I wouldn't wait too long.

 

Remember timing belt is warrantied to 60k miles. When you do change it make sure to change the timing belt, belt tensioner and balance shaft belt also. If the timing belt breaks or comes apart and you are out of warranty make sure to change the crankshaft position sensor and crank blade also.

 

Hi Guys ,Thanks for the replys , will be changeing it next month for sure, figure better safe then sorry, now dose anyone have a site that shows a diagram of the timeing belt for a 2.4 DOHC , none of my books show it (not new enough) . Going to do it myself ,don't figure its that big of a deal, thanks again Slimone
