Not long after I purchased my truck a few months ago, I purchased a Spartan system. At first, I just hooked up the Spartan dashdaq to monitor things and see if I had any problems I needed to get fixed under warranty before I did my DPF delete and tune. Sure enough, my EFT1 temp was running higher than what I had read on this forum that it should run. I took it to the dealer to check out, and they said there was nothing wrong with it. So, I went ahead and did my delete and tune. Over the next couple of months, the temp kept climbing. On a long trip a couple of weeks ago, I was seeing up to 168 F. I knew I had to do something.
After troubleshooting starting with Jeff from Spartan and ending with Greasltn from Rudy's, I discovered that I wasn't moving coolant in the fuel cooling system. I ended up replacing the coolant pump, and everything's fine now. Thanks, guys!!
I'd just like to make the point that if I hadn't had the Spartan system monitoring my truck, I would have never known that this temperature was running hot (never got a check enging light) until it eventually cavitated my HPFP (which I figure would have happened) and cost me an arm and a leg to repair. I'm now hardcore loyal to Spartan, and I appreciate Jeff and Greasltn putting up with and answering my many PM's while working through the issue.
