Coolant Service
It’s Getting Hotter Out There; Know How to Keep Your Customers Cool Coolant testers, pressure testers, flushers and exchangers. These are the tools and equipment shops need to keep their customers’ cooling systems cool. We’ve had an unusually hot summer this year. Record high temperatures across the country have left many vehicles steaming alongside the
Robinair Introduces the #10986 Orifice Tube Service Kit
The screened orifice for AC cycling clutches requires this special puller from Robinair. Use this kit to remove complete or damaged tubes in 1985-and-later Ford and GM cars.
Diagnostic Dilemmas: Internal Engine Diagnostics
The nuts and bolts of measuring cylinder leakage In OBD II diagnostics, most of us know that an external component like a faulty fuel injector, ignition coil, spark plug or spark plug wire is usually responsible for a P0300-series cylinder misfire trouble code. Nevertheless, even with more sophisticated onboard diagnostic strategies, the PCM usually can’t
Tech Tip: Updated Routing of Volvo O2 Sensor Wiring
New routing has been developed for oxygen sensor wiring on 1997-’98 Volvo 850 models, S70/V70/C70, to prevent contamination from reaching the probe’s reference air. If one oxygen sensor is replaced, the new adapter wiring must be installed for both sensors.
Tech Tip: Are You Testing Your Customers’ Brake Fluid?
When was the last time you tested a customer’s brake fluid? Never? Many shops don’t bother to test brake fluid for several reasons. Some don’t think fluid tests are necessary. Others don’t test the fluid because they don’t have anything to test it with. And others say why bother if they’re going to bleed the brakes after relining the brakes?

Diagnostics Through CAN Networks
Since model year 2003, a growing number of domestic and import vehicles have been built with a new onboard communications protocol called CAN (Controller Area Network). CAN is essentially an engineering standard for how computers and modules talk to one another via the serial data bus in a vehicle’s wiring system. It’s a high speed
Tech Tip: Flushing Away Engine Problems
When motor oil isn’t changed often enough, varnish deposits and sludge begin to form inside the engine. If the oil is neglected long enough, it will eventually turn into goo and ruin the engine.
The Future of Diagnostics Is In The CAN

Tech Tip: Rust and Corrosion May Be Culprit When Signs Point to Faulty DIS Modules
A vehicle towed into a shop is a "no start." Preliminary troubleshooting leads a technician to suspect the culprit may be a faulty DIS (Distributorless Ignition System) module. So the module is bench tested using the ignition module tester, but the results show the component seems to be working fine. The DIS module is placed back on the vehicle and the troubleshooting continues.
