Service

Good afternoon.

The fuel filter is inside the tank and part of the fuel pump module. That is why there is no mileage interval.

The belt is an item that is to be inspected at each service interval. It will or should be replaced when cracks appear or the metal ribs are showing.

Belt replacement under any or all of the following conditions is required:

- Excessive wear

- Frayed cords

- Severe glazing

Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not.

Note:
Do not use any type of belt dressing or restorer on Poly-V Belts.

The fuel filter is inside the fuel tank and is not a service item, it usually only gets changed if the pump fails or someone contaminates the system.
As for the accessory drive belt, It is changed when it shows the signs it is excessively worn or damaged. Those would be frayed or damaged sections, cracks that run along the belt or V ways.
Personally on my vehicles I change the belt(s) and hoses at around 75,000 because they will still look fine, right up until they fail. I usually change the tension-er as well.

Generally I look into a belt replacement around 50,000 to 60,000 miles, or after I put that many on a vehicle after I get it. I just find it unusual that Dodge does not have it under any of the intervals to be checked.

Gates and Dayco recommend 90,000 unless there is evidence of wear or damage. The only vehicle I ever had that was bad on belts was a Jeep Cherokee, it was a stick and if you were really standing on the gas and bobbled a shift even a bit it would snap the belt and the broken belt would smack the hood hard.

These days most do not list it because the idea given to shops is to check it but, until there is an issue you do not replace it, unless you are replacing something like the alternator or AC compressor then it is added into the repair.
Does your 2013 still have a transmission dipstick? Most of those are gone these days. Some makes are even lacking an engine oil drain!

No transmission dipstick. If there is no engine oil drain pan, where does the oil drain to? Mine has an oil pan.

They have a pan but no drain. VW and BMW both build models like that, and others are starting as well. You need to use an extractor to change the oil using an adapter fitting.

If you want to "make" a dip stick for the trans you might want to watch this video.

The only issue on my 2013 is there is no plug on top of the transmission for access.

Check way down on the front side for a very short tube with a cap on it. It is not easy to see where it is hidden. On the 2014 Journey we have (same drive-train) it is all black and tucked into a notch where you cannot see it.

Is it one of those setups where you can fill it until fluid leaks out then you know it is full? Like a 4x4 vehicle.

If you are talking about the Caravan and Journey, both are filled and checked through the capped tube.

If I were to get to the cap, how can I tell if it is full or needs filled?

That video shows how to make a dip stick to check it. To do it by the book you need to know the current transmission temperature, some have that as a visible item in the DIC under vehicle information. Otherwise just check it cold and look at the chart. It uses ATF+4.

In other words, they have made it harder than it needs to be.

Yep. And it is getting worse because many of the companies want to get to the point that only the dealers and "properly certified service centers" (dealer owned or similar) will be able to work on the vehicles. This is one of the reasons why the right to repair laws are being pushed.
