Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default 3208 Low Power, Overheating

Hi everyone,
Im close to 4,000 miles in to a cross country road trip with some friends and having some trouble. I have a 1978 FC31 with a 3208NA. It was running well until we got to the Wyoming/Montana area. It seems to be fine on flat roads or downhills, but really struggles on any hills and black smoke comes from the exhaust if I give it too much throttle. It started overheating yesterday climbing a mountain just north of Boise, Idaho on route 55 just south of horseshoe bend. I recently replaced the air filter and the fuel filter but it didn't seem to make too much of a difference.
Im not the most mechanically inclined when it comes to engines, but I know some and Ive got some common sense. Any help would be appreciated.
Thanks, EJ.

Try taking the top of the air cleaner off, and see what happens.
I added the 4in extra air intake, saw it in the archives, and it helped
I think black smoke means to much fuel, not enough air

Altitude is your issue.
Boise is at 2800 feet, and climbing a mountain with an NA 3208 will be tough. Gear down and go slow when climbing. Yup, you may need to stop to cool down as well. Black smoke means too much fuel and not enough air. That is to be expected with an NA at higher altitudes.

Also, they are probably pumping 'Winter blend' diesel by now and that has a little less power.

Gardner speaks the truth!
Its hard to back off the throttle when your climbing,but thats just what you have to do!
Gear down,pull your right foot out of the engine and enjoy the long slow ride to the top.

Great, thanks for the help everybody! I'll be heading back down towards Portland, OR soon so I can see for sure if the issue is altitude. Thats what I expected, as the toughest climb to make was a 10,000 footer! Thanks again for the advice.

Even I have trouble breathing at 10,000 feet
