Timing Belt

Hello all!
I have a 10/2003 2.4TJ with 45000miles on the clock.
Manual says replace the timing belt on 90000miles.
My mechanic says 90K or 96 months(about now)which one
comes first...
What do you think?

I would say it does not sound like a bad idea to replace it now at 45. I know a great many import cars have it done at 55 or 60k. So based on how old the belt is vs the low miles might be good peace of mind for the next 90k miles or 8 years.

Wranglers do not use timing belts, they use chains. The chain doesn't need to be replaced any sooner than the engine needs a full overhaul.

The 2.4L engine does indeed use a timing belt.

You might want to do your homework on the 2.4 four cylinder motor.

Oh, my bad, didn't know that. I always forget the 2.4 is not an AMC engine than the 2.5 and 4.0. Anyway, that suck it has a timing belt. My parent just had to replace the timing belt on their Infiniti, cost 800$, should be a lot easier on a Jeep though.

My 1991 Honda Accord 4 cyl says to replace the timing belt every 80-90,000 miles or 6 years. Mine was replaced for the first time 3 years ago (17 years old) at 75,000 miles and the Honda mechanic had a hard time finding any cracks in the old one to show me how much it needed replacing. Said it probably would have lasted another several years.

Course I don't know if you can compare a Honda with a Jeep, and I have both. I had to replace the front bearing hubs on the Jeep at 8 years old and 54,000 miles but the Honda is still going without any sign of wear or noise. Disc pads on the Jeep have been replace twice and the Honda still has the original front pads and rear shoes.

Well, my jeep just got broke the timing belt. I assume I should change the water pump as well since I am there. I just hope this is the only problem it has. Is there a worst scenario?

Replace the timing belt, water pump, front cam seal and front crank seal while you are in there.

That's what the little used search feature is for.

Belt/HAVC Repair

Hi...I just replaced the belt on a 2005 wrangler X that I purchased from a private party. The vehicle only has 41K, however, for 35 bucks and five minutes of work, I believe it's called preventative maintenance. I also repaired a vacuum link, now my HAVC control is working properly...this took quite honestly one minute.

I'm assuming your talking about the serpentine belt.. The X has a 4.0L 6cyl. Which has a timing chain, which rarely if ever needs replacing. The 2.4L 4cyl DOHC has a timing belt which takes minimally a couple hours to change out
