We bought a T2000 with the 2006 Cat C15. She was getting over 6.7 mpgs. Then we sat idling the truck 4 days in Miami. Mpgs have gone down to about 5.5 at best. No missing or rough running, just poor mpgs.

How often does a cat C15 engine die?

Lately, it’s also been real bad about losing prime, so about one out of ten times I start it up, it loses prime and dies, then I have to use starting fluid to get it started again. I’ve had it in the shop, both Cat and Peterbilt, more than 25 times, every test in the world has been run on it, and no one can figure it out.

Why does my cat C15 engine have a vacuum?

Problem now is, no matter what filter i put on there, it is too restrictive, and so it is aerating the fuel and creating a vacuum on the engine (exit) side of the filter base. This is all theory, mind you, based on my own work. If this isn’t it, then I must have some restriction elswhere on the pressure side.

95′ 378. AC is not working. System is charged but compressor clutch will not engage. No power at compressor. It does engage if I jump it off a 12V source. I have power in and out of hi and low pressure switches. Any thing I’m missing or do I need to start looking for a broken wire somewhere?

What causes a C-15 cat engine to spin faster?

Downshift until you are pulling under 20 PSI on the manifold pressure and have your RPMs over 1600, this will cause the fan to spin faster and cool better. As for your fuel mileage, that is very common for an ACERT. Sounds like a typical ACERT to me.

We found a dent in a male fuel supply line fitting. The fuel was not leaking out of this fitting but it allowed the engine to suck a small amount of air and was causing the engine to run rough and miss fire.

Why does my C15 Cat truck not start?

Check valve would be the likely cause for the “won’t start after a day or so” but shouldn’t account for the “starts, runs for a minute or so then quits” and does this twice back to back. All the valves do is hold pressure/ prime when it’s not running.

Where to find air in a cat C15 engine?

If air is entering system, the air will be seen with a site glass at the pump inlet (hook up to a “known good fuel source” if you question it). Air might also be found on the return line to the tank, but be careful as some bubbles in the fuel is normal.
