Probably not. I'm worried about the unibody transits that will only have a 3.7l V6. Doesn't seem to me that it would hold up nearly as well as our Chevy Express 6L V8 3500 trucks, and I'll need it to haul and do the same stuff.
One of our units has the smaller V8 and we've had a ton of problems with it, it just failed at 160k. Maybe I'm wrong.
Yeah. That makes sense. The larger 6L seems like it would handle the high idle better. Do you think the smaller engine gave out because of the heat of running stationary?
Run synthetic oil to eliminate the chance of sludge build-up and no truck engine should be prone to heat-related failure.
The smaller GM engine needs to be ordered with a tow package to protect the transmission and power steering (extra coolers) or you should add those bits yourself. The 6.0 comes with that stuff now, as well as a more durable transmission.
In 14 years of running a fleet of GM vans we've had only one engine related problem. A valve spring shattered and the pieces jammed the valves open and dropped into the cylinder and scarred it. Manufacturing defect in the spring.
I guess we'll see which unibody trucks with smaller, higher output per cc engines not just last mechanically, but are as solid as an old Ford or Chevy van once they got some heavy miles on them. Some newer vehicles with plastic intakes, stamped steel exhaust manifolds, or plastic hoods and fenders. just seem like gum wrappers - crunch and toss when they show wear.
