A smoke machine may seem like an expensive piece of equipment if it is just used for testing EVAP systems. But, if you factor in other diagnostic tests it can perform, it is a worthwhile investment. The following are 10 tests for smoke machines not involving the EVAP system.]]> http://www.diagnosticnews.com/featured/tool-tip-10-diagnostic-tests-for-smoke-machines-besides-evap/feed/ 0 http://www.diagnosticnews.com/featured/brake-system-scan-tools-the-new-essential-tool/ http://www.diagnosticnews.com/featured/brake-system-scan-tools-the-new-essential-tool/#comments Tue, 24 Apr 2012 12:23:36 +0000 newsadmin http://www.diagnosticnews.com/?p=10287 By Andrew Markel. While there are many times where you will be able to repair a vehicle’s brakes without a scan tool, you only have to run into one car that needs this to make it worth having. The reality is that if your customer’s vehicle is 10 years old or newer, there’s nearly a 100% chance that you could need a scan tool to perform some sort of test/repair on the brake system.]]> http://www.diagnosticnews.com/featured/brake-system-scan-tools-the-new-essential-tool/feed/ 0 http://www.diagnosticnews.com/tech/brake-myths-revisited/ http://www.diagnosticnews.com/tech/brake-myths-revisited/#comments Tue, 10 Apr 2012 20:11:28 +0000 newsadmin http://www.diagnosticnews.com/?p=10201 By Andrew Markel. The overall response to the 7 Brake Myths Busted article was huge. I took a lot of abuse, but that was the goal of the article. Too many times technicians get stuck in a mindset that leads to false diagnoses. The point of the article was to shake things up in your diagnostic thinking. ]]> http://www.diagnosticnews.com/tech/brake-myths-revisited/feed/ 0 http://www.diagnosticnews.com/tech/7-brake-myths-busted/ http://www.diagnosticnews.com/tech/7-brake-myths-busted/#comments Wed, 14 Mar 2012 16:02:23 +0000 newsadmin http://diagnosticnews.com/?p=9854 By Andrew Markel. There are some myths about brake pads, rotors and hydraulics that need to be busted. These myths can hurt and hinder a technician’s ability to diagnose and solve some brake problems and customer concerns. On the surface, some of these myths make sense. The logic can seem sound and explain a problem, but they do not resolve the real issues with a brake system.]]> http://www.diagnosticnews.com/tech/7-brake-myths-busted/feed/ 2 http://www.diagnosticnews.com/tech/finding-electrical-shorts-on-multiple-circuits-2/ http://www.diagnosticnews.com/tech/finding-electrical-shorts-on-multiple-circuits-2/#comments Tue, 07 Feb 2012 14:45:16 +0000 newsadmin http://diagnosticnews.com/?p=9538 By Scott 'Gonzo' Weaver. When I was a kid, I saw a movie called “Juggernaut” with Richard Harris as the main character. It was about a cruise liner that was about to blow up because a terrorist had planted 55-gallon drum bombs all over the ship. The premise of the story line is that Harris was going to save all the people on the ship by defusing the bombs. All through the movie, there were references to the different relays and electrical circuits.]]> http://www.diagnosticnews.com/tech/finding-electrical-shorts-on-multiple-circuits-2/feed/ 2 http://www.diagnosticnews.com/tech/tech-talk-boosting-your-technical-knowledge-on-turbos/ http://www.diagnosticnews.com/tech/tech-talk-boosting-your-technical-knowledge-on-turbos/#comments Tue, 07 Feb 2012 14:01:37 +0000 newsadmin http://diagnosticnews.com/?p=9516 By Dave Hobbs.

This is sure to be an interesting read full of new information for anyone interested in the science behind modern automotive oils.]]> http://www.diagnosticnews.com/tech/oil-additives-supplements/feed/ 3 http://www.diagnosticnews.com/tech/cooling-system-contamination-repeat-component-failure-requires-heroic-efforts/ http://www.diagnosticnews.com/tech/cooling-system-contamination-repeat-component-failure-requires-heroic-efforts/#comments Mon, 22 Aug 2011 20:17:56 +0000 newsadmin http://diagnosticnews.com/?p=8442 By Kevin S. McCartney. Modern engines rely much more heavily on the lubrication system for cooling than ever before. Oil coolers and coolant heated PCV systems present some new opportunities. But, there is a great deal of overlooked technology in modern motor oils that should be understood before this opportunity is addressed. ]]> http://www.diagnosticnews.com/tech/cooling-system-contamination-repeat-component-failure-requires-heroic-efforts/feed/ 1 http://www.diagnosticnews.com/tech/free-the-ecm%e2%80%99s/ http://www.diagnosticnews.com/tech/free-the-ecm%e2%80%99s/#comments Fri, 19 Aug 2011 19:34:43 +0000 newsadmin http://diagnosticnews.com/featured/free-the-ecm%e2%80%99s/ By Scott 'Gonzo' Weaver. Sometimes, I’ll find faults with the so called “experts” advice or information. Not that I think I’m smarter than the engineers… no, not that at all. But if something strikes me as not being completely correct I might want to question what is on that diagnostic tree. Mind you, my entire day is filled with meeting the expectations of my customers. I have to be dead on with my repairs and diagnostics. Not some of the time, no, ALL the time. And, I expect the same from the people that provide the information and parts. The way I look at it, you’re only as good as the information provided.]]> http://www.diagnosticnews.com/tech/free-the-ecm%e2%80%99s/feed/ 0
