Hi,

The timing belt on my 1998 Dodge Caravan with the 2.4 liter DOHC broke while trying to jump start it.
I have gotten conflicting info as to whether this is a non-interference fit engine. Anyhow I used a Chilton manual with a crummy diagram and replaced the belt. I'm not sure if I got the timing marks right Both of the cam sprockets say this side UP, but the timing mark on the exhaust side position that sprocket down.

Any link to a good online photo of the cam sprockets in the correct position? Also,what needs to be done to reprogram the computer after replacing the belt? Looking for the correct answer as to interference or non-interference. How should I proceed? I cranked it and it seems like weak compression now and no spark.


thanks

Upside, 2.4 is a NON-INTERFERENCE engine.

Downside, getting the cams to line up right does take a bit of time.

Beginning in 2001, the 2.4 is listed as interference, so a 98 should be OK. The belt change interval is 120,000 miles per Gates. What was the mileage on yours when it broke?

Water pump is driven by the timing belt, so you might want to change it too if it is original.

Thanks for the replies. i found the Autozone link after I posted. It is a good one. Wish I had seen it before I put it all back together with the exhaust cam off by 180 degrees. Chiltons diagram isn't clear. Oh well, time to redo it. At least I know from experience that the harmonic balancer covers the end of the crankshaft. Once I discovered that I used the crank bolt head loosened a few turns as the "footing" for my pulley puller. I did it in stages and backed the bolt out several times slackening then tightening the puller.

Thanks John,

122k on the belt. It broke while trying to jump start a dead battery. As I mentioned numerous conflicting references as to interference or non. I guess I will find out when I take it apart again to get the cam timing right.

Great forum here. Thanks again for all the helpful replies
