No power until egine is fully warmed up?
I am still searching for my new (to me) 6.0 since I sold my Cummins 3 weeks ago. I found a 05 XLT PSD 4x4 with 82K for $16K. Older guy who knows nothing about diesels has it, but a few thousand mi ago his son blew a EGR cooler and head gaskit and kept on driving. So long story short, he had a shop install a used motor w ~90K on it. I am meeting him today to check it out, and to get all the paperwork and the contact info for the shop that performed the swap. Says it was "fixed right" (whatever that means) and the shop told him there would be no more cooler probs. I am hoping this means it has already been upgraded and hopefully studded, we wil see.
Anyway, he has put 3-4K on it since and says it drives like a dream. The only problem he is having is that it HAS to warm up for 5-6 minutes no matter what the weather, or it has no power. Is this a normal PSD symptom? I ALWAYS warmed my Cummins up before trying to drive, so I've never really noticed this. Not sure if this is him just being gun-shy and looking for problems now, or a sign of something else.
I am going to go drive it in a few hrs, will have my ScanGuage so I can monitor my coolant/oil delta and I plan to let it sit for a while and then start to see if I can observe what he is talking about. Thanks in advance guys
