What is this cooler for...


Recommended Posts

Not sure what this cooler is for but I've got a good guess...

 

The cooler is located just after the frame crossmember and before the fuel tank. I'm guessing it has diesel fuel running through it, but my question is... what is the purpose?

Diesel is used to cool the FICM (bosch electronics on valve cover). That cooler cools the fuel off on the way back to the tank.

Thanks, Jay...

 

This is my first diesel, and I jumped in with both feet not really knowing all there is to know about the Dmax.

 

I noticed the cooler a few days after I bought the truck, but never really knew what the exact purpose was. Now I know...
