Revolutions: Coal Liquification

Extra

US energy policies and practices affect the ability of "We the People" to continue driving our diesel vehicles.

Shortly after World War II, the United States started to import oil in order to meet its growing demand for finished petro-chemical products. The rapid escalation of plastics used in packaging, domestic utensils, automobiles and virtually every aspect of American life added to the increasing demand for petroleum. Electric generating plants that run on diesel have been easy to construct as have steam plants supplied by petroleum. This has added to the ever-increasing demand curve for petroleum. Along the way, US domestic production has increased but it could not keep up with the rapid increase in demand. As a result, petroleum imports surged to ever higher levels. Electric generating plants began to shift to burning domestic coal and natural gas, however, the demand for petroleum has not slackened. Nuclear power plants came on line with great promise. Unfortunately, public hysteria cut short the promise of a nation powered by nuclear generated electricity. Modern clean coal fired generating plants began to replace old less efficient power plants with great promise to use the vast quantities of domestic coal reserves in the US. Again, this promising technology would fall to public hysteria: smaller in number than nuclear opponents, they compensated with fanatic hyping of man-made climate change, global warming.

Should Their Be Metal Sleeves for Control Arm Bushings on My '99 Suburban?

6.2/6.5 Issues and Answers

I have a ‘99 2500 Suburban, when I replaced the lower control arm bushings the replacement bushings had a metal sleeve, however the originals had no metal sleeves. I took the control arms to the dealership and even their head suspension mechanic had no answers.  I ended up buying new complete lower control arms and they also had sleeveless bushings.  Can anyone tell me why everywhere, including the Chevy dealership, only sold sleeved bushings.  I was told I left the bushing sleeves in the control arms.  However the old ones don’t have any and the new replacements didn’t have any.  Any help on this would be greatly appreciated!

   

1998 6.5 Engine Runs Well at High RPM but Smokes at Lower RPM

6.2/6.5 Issues and Answers

Hi there. I love the magazine! I have a 1998 GMC 1500 Z71 Sierra extended cab 4x4 6.5 automatic. It has 170,000 miles on it. Engine codes are P0236,P1409,P1653,P0401,P400. I have installed new CDR valve, Vacuum pump, Wastegate Solenoid Valve and both EGR Solenoids. It bellows black smoke with no power until the rpms come up and the boost. Then it runs pretty good until I slow down . If I unplug the vacuum line to the EGR and cap it off it runs fine with no smoke at all but then the check engine light comes on. I have to get through emissions so I can keep my truck registered. Any help would be great, thanks. Kurt B. – CT

   

1996 6.5L Radiator Gets Too Hot When I Idle

6.2/6.5 Issues and Answers

I’ve got a cooling issue with my '96 6.5. I have cleaned the radiator and other coolers and even put on a new fan clutch but when pulling a load especially at low speeds the engine will run at 210 or just over. If I let it set and idle or high idle with the A/C on it will run up to 220 and you have to drive down the road to cool it off. Never had it flushed and it still has the single stat setup. I do have the dual stat setup but after reading the last issue am not sure which is the best route to go.

   

Setting Code 78 and Heavy Black Smoke

6.2/6.5 Issues and Answers

I have been having a problem with my 1995 GMC 3500 HD dump truck and maybe you will be able to help me out. For some time now, my truck has been having a service engine light. I had it checked and find that it is setting a code # 78. When it does this, it also smokes heavy, black smoke. Our Chevy dealer checked it out and replaced the boost sensor on the top of the engine. However, this repair did not fix the problem and he tells me he is stumped. A mechanic friend suggested that it was a bad vacuum valve and that we ought to tie the boost lever with wire to hold it closed. The truck no longer smokes, but it still turns on the service engine light and sets code #78. So now, I don’t know what to think about this problem. Is it too much boost or too little? We seem to be out of options. Can you help?
