Looks Like a Mini Radiator in front of Main

Talking about a 2017 Dutch Star 4018.

When you open the grill to look at the radiator, there is what looks to be a smaller radiator setting in front of the main radiator. What is this?

There appears to be a small leak in the bottom right corner. Not enough to leak onto the ground, but showing wet area in the corner and just below on the tray.

Trans cooler is typically located where you are describing. Separate and completely different system to the engine radiator. Post a picture if you can and we may be able to confirm for you.

It is the smaller square in the front/right. There is a part number on it, so I included a picture of that as well. At least, I hope I did. I am not necessarily proficient at attaching files.

Googling those numbers on the side and I am getting photos of an AC Condenser? Does that sound right?

In that location, you might find either a fuel cooler (in the return circuit from engine to fuel tank OR a dash A/C condenser.


I am not a fan of putting the A/C condenser there, as they do require air flow to work properly. And, if engine coolant temperature does not call for higher fan speed, condenser efficiency can be compromised.


I did have one DP with the condenser in that location. To add freon, I had to have someone misting the condenser with a hose in order for it to work properly (engine not up to operating temperature.


That location for a fuel cooler is just fine, as fuel in the tank will not be overheated before the engine reaches operating temperature.
