To know for sure if your specific 2007 Dodge Caravan has a dedicated transmission cooler, you should:
* Check your owner's manual: This will provide the most accurate information about your vehicle's specifications.
* Inspect your vehicle: Look under the front of your vehicle. A separate transmission cooler will usually be visible as a smaller radiator-like unit near the main radiator. If you don't see one, it's likely integrated into the radiator.
If you're considering adding an auxiliary transmission cooler (for towing or other heavy-duty use), that's possible regardless of whether your vehicle already has one. But adding a cooler when you already have one built-in (either separately or within the radiator) may not be necessary unless you're putting significant strain on the transmission.
