It sounds like a fuel problem. Check your fuel filter/water separator (sometimes there are more than one filter), and replace if clogged, or if you don't know the last time it/they were replaced.

Where to find belt routing diagrams for freightliner condors?

Freightliner doesn't have a model called the "Condor", and never has. And yes, I get that you mean "condo", but the sleeper configuration has absolutely nothing to do with how the belts are routed. Was is vital is the information you've excluded... that being, the model year and engine make and model. So, as is, we don't know if you have a 12.7 60 Series Detroit, pre-ACERT Caterpillar, post-ACERT Caterpillar, or Cummins N14 or ISX.


On a Caterpillar with ACERT technology there are 4 integral systems. Two of them are Air Management Systems and Advance Fuel Injection Technology. What are the other two?

Depends. If it was one made during the 6NZ era (which, IIRC, ended circa 2004), yes. The MBN, 'bridge' Cats, and ACERT models were junk, though.


How reliable is a double turbo C-15 caterpillar engine?

Not very. The 6NZ - the last of the single turbo Cats - was probably the best on-highway engine Cat ever made. Anything after that - MBN, Bridge Cat, and especially ACERT - was junk.

How does air management systems on caterpillar engines lower emissions?

It's more than a air management system - Cat's ACERT system uses series turbocharging to force air into the intake system via two turbos - one little one (on top) and a big one on the bottom! This lowers CO2 and carbon emissions by 70%, just like SCR in Europe! Visit these two links to find out more: ACERT off highway: http://www.cat.com/cda/components/fullArticle?m=48920&x=7&id=142378 ACERT on highway: http://ohe.cat.com/cda/layout?m=115235&x=7 With the ACERT OHE link, there is a couple of choices to choose: EPA '04 or EPA '07! Take your pick! Joe
