Hey folks, new to this forum. Found it by looking for a specific problem on the web. I see where some of you had this same problem: I noticed a fuel leak under my '06 crewcab 3500 DMAX just in front of the fuel tank. Investigation revealed what appear to be, at first glance, a small heat exchanger/radiator on the return line. After scratching my head a while, wondering what ever could this be (I'm relatively new to diesel technology), I decided to call my Dad. He is an old school self taught diesel mechanic (owner-operator 18 wheeler) and is always my first call when working on anything mechanical. He of course, was not familiar with this particular application of a cooler on a return line and thought it might have something to do with helping to heat the fuel for winter-time. However, as I pointed out to him, this cooler was on the return line and had no additional lines for adding heat. So, being stumped, and needing to get to work by monday morning, I removed the cooler, cut the leaking fittings off and hose-barbed the to lines together.
Here's my question(s): What negative effects will this have on my DMAX? How much good does that thing really do, buried inside the frame rails with little air movement? SHould I look to re-install with better (stainless) fittings? And if so, where would I find them? Thanks in advance.
