so basic question.. the 2.4l tigershark is a timing chain or belt. The googles doesn't have a solid answer. I saw one forum thread someplace that said chain, and the cherokee service manual doesn't have replacement on the maintenance schedule, so I'm assuming chain, but anyone have a good source confirming that?

1.4L - Belt

2.4L - Chain

I am eyeballing the Renegade TH but I flat out won't buy it if the engine has a belt.

Some stuff I've seen on the web says the 1.4 is a belt and the 2.4 is a chain.

I would think those that are interested in the 1.4 turbo won't care about a belt but those interested in the TH would want a chain.

I care about a chain. Timing belt service is getting to be stupid expensive for a lot of cars.

For my next car I'd really like a timing chain, and easily accessible spark plugs. These are things subaru has beaten into me. $1300 timing belt changes and $500 spark plug changes (cause hey, it needs and engine hoist and lots of labor) are things I'd like to avoid going forward.

Even subaru hjas moved to timing chains. I think they realized that by 100k or so, even if everything works as normal, having to fork out $2300 in scheduled service adds to the cost of the car. Add on that the subaru burble is really unequal length exhaust that means you cna flip a coin if one of the cylinders runs hot and needs a new head gasket by that time for another $1000 or so.... well.

It's easily the most expensive reliable car I have owned. Outside of that, the fact that new plugs isn't something that means 20 minutes out in the driveway plus the cost of plugs irks me.

Spark plug access would be important for me too. I had to replace the coils in my RAV4 with the V6 and I thought I'll do the spark plugs also while I'm in there. PITA. The 3 in the back were very hard to get to.

The belt on the 1.4T on the Dodge Dart is serviced at 150K miles, I assume Jeeps will be the same since they share an engine.

they should, if not i don't see it being too far away from that mark
but i would suggest changing it before that...after all it is a very important part.

150k or 10 years is the suggestion in the Dart Manual. I doubt I'll have the Dart that long, I'm looking at the Renegade, the 'Compatriot', Dart SRT or the Journey Replacement SRT.

That's curious. Until last year I've owned a Fiat Punto 1.4 T-jet (turbo). Belt change recommended every 60.000 km or 3 years. At launch the interval was 120.000 kms. They changed it due to massive complaints about snapping belts.

I hope the Renegade will have the 150.000 miles / 10 year interval, it would save a lot on maintenance.

150,000 miles is a long time for a belt. It will be interesting to see if the belts truly last that long. I wonder what they have done different to extend the life an additional 50% over the typical belt life.

That's also why i would consider changing it before, if this snaps...well..it's going to be ugly.

150k should be worst case scenario.

Timing belt

Does the 2.4 have a timing belt that needs changing between 36k and 72k miles? And is it a PIA as in removing the motor mount?

 

[Greenjp]

Somewhere on the forum it said it has a chain not a belt. Can any one confirm?

 

[Rivmage]

The 1.4T is a belt and the 2.4L is a chain. That is the setup in the Dodge Dart and I doubt they would change for the Renegade.

I would prefer that it comes with a belt, i have heard way too many bad things about chain driven systems.

 

[DogsRule]

Thanks JeepSix. Thats the pic I was looking for. It has a chain. I can sleep now.

Now if I can go 18k miles between oil changes, that would be nice too.>

like what?

Other than increased rotating mass, and slightly more mechanical noise form the engine, there's ZERO wrong with them and they incur less maintenance costs on the owner.

timing belts are cheaper for the manufacturer, decrease weight, and ensure some nice high ticket maintenance items for your dealer network. The only thing the retail buyer gets out of that is the low weight and potentially increased fuel economy from that. The fact that a number of auto makers trying to imporve fuel economy while trying to deal with a customer base increasingly opting for 72+ month loans choose the timing chain.

You beat me to it. I cannot imagine anyone having a preference for belt. Chains are considered a non-maintenance item, even on high mileage engines.

I just replaced the timing chain on my daughters Scion (Toyota) xA with its 1.6L and at 185k the chain and plastic guides all looked like new, no wear, just a little bit of stretch. I was impressed.. Much better than the old 60's Ford 289s I used to rebuild. Yuck.

Belts are nice. But I do love a good chain.
