Subaru Air Conditioning Tech Tips
To assist you in your repairs of Subaru air conditioning systems, we have compiled several air conditioning tech tips provided by the Subaru Technical Helpline.
Certified Inspection, Part 1
You can run a business the same way you live your life. To keep both vital, it’s a good practice to periodically review what you’ve grown accustomed to doing. It’s been nearly three years since “Front Counter Mechanics” last discussed marketing. Business has changed since then, and it’s time to revisit and reconsider some of […]
Catalytic Converters and OBD-II Monitors
Can you remember the first new car that had a catalytic converter? To sharpen your recollection, the first catalytic converters were introduced in the mid-70’s when the Clean Air Act was first signed into law. The first car to meet the 1975 emissions standards was a Chrysler Avenger, and it was equipped with a rhodium-promoted […]
D-Jet Rules!
The Mother of All (well, the mother of most) Fuel-Injection Fuel injection for automotive engines goes back at least to the folks at Gasmotorenfabrik Deutz in 1898, whose mechanical plunger-pumps fueled turn-of-that-century engines until those goldurned newfangled contraptions, carburetors[!], supplanted them. Almost since then — since 1912, that is — Robert Bosch GmbH of Stuttgart […]
1988-1991 Honda Civic Dual Point Fuel Injection Part Two: Diagnostic and Repair Tips
Last month we examined the behavior of a failed TW sensor on a 1991 Honda Civic. This month we’ll add a few more details to the diagnosis, and explain the other components that make this system tick. How do the injectors and main relay work? Which injectors fire when? And what about that alternator control? […]

Subaru Air Conditioning Theory
How does air conditioning cool the interior of a vehicle on a hot day. Like a lot of things, it all comes down to basic science. That’s why a good understanding of air conditioning theory begins with the Basic Principles of Heat Transfer.
Go to your room – you’re grounded!
I’ve always loved troubleshooting ground problems. Well, maybe not always. Certainly not until I figured out the best way to do it. But once I found the method for troubleshooting grounds, I began to enjoy watching the bizarre behavior of ground circuit problems. The more bizarre the problem, the more I liked it, because they […]

Into Thin Air Part Two
In the March Import Service, we began a discussion of OBD-II evaporative emissions systems. We explained system operation and the problems engineers face when designing the monitoring devices for these systems. We also looked at the early Toyota evaporative emissions system and explained how the charcoal canister functions. This month we will continue with Toyota […]

1988-1991 Honda Civic Dual Point Fuel Injection, Part 1: Features and Troubleshooting
Honda introduced the 1988 Civic with a completely new fuel injected engine.
Cracked, Warped and Twisted Heads
Aluminum cylinder heads are now pretty much standard fare for car engines by reasons of weight, cost and heat transfer.
Subaru Air Conditioning Mechanism and Function
This article provides an overview of each Subaru air conditioning system component’s basic mechanism and function.
Into Thin Air, Part One
A major feature of the OBD-II system is its ability to monitor the evaporative emissions system.
Twenty Groups
If you belong to any professional associations or are active in iATN forums, you may have heard the phrase Twenty Groups.
Waste Spark
From the point of view of gasoline mixed in the right proportion with air, the polarity of a spark doesn’t matter one bit, only the voltage.
Casting a Thermodiagnostic Spell: Solution-Sorcery with a Noncontact Thermometer
The key to the spells we’ll cast here and a symptom of many things that can go wrong with any kind of machine is heat – in the wrong quantity, in the wrong place – produced by friction, by excess electric current, by flame, by acidic chemistry.
Autodiagnos Multi-Tester pro
The latest addition to the Swedish-made Autodiagnos line of diagnostic equipment is the Multi-Tester pro.
Repair Shop Confidential
It’s been a couple of years since I bailed out on wrenching and got into the detective business. You might say I traded my safety shoes for gumshoes. It was easy money right from the start. I specialized in locating misses. Most of ‘em were a piece of cake. Just round up the usual suspects […]
