Read our review of the Velocity Channel's popular DIY show.
Updated: February, 2016
This is the second season for Tech Garage. They're not just rehashing topics they covered last year, but getting into a whole bunch of new stuff to keep you interested and keep you learning. Tech Garage
features John Gardner, an ASE-certified master mechanic and automotive instructor at Chipola College
in Marianna, Fla., and Bryan Gregory, also ASE-certified and always ready to get his hands on a car project. The premise is simple, explaining how cars and their various systems work. There’s no reality show drama here, but there are plenty of key tips. Whether you’re a heavy DIYer who can handle pretty much anything under the hood or a 15-year old dreaming about the day you can drive, you’re going to learn something new about vehicle mechanics from watching this car TV show.
On one of the show’s first episodes, Gardner explored the vehicle’s battery
, charging and starting system. What makes the show unique is that he doesn’t just explain to viewers how the systems work and leave them with only a cursory understanding. He breaks the system down and provides an in-depth explanation of not just how it works but why, and he uses some pretty cool, functioning system displays that any gearhead would love to have taking up space in their garage or man cave.
For example, in that first episode Gardner goes under the hood to diagnose a lack of starting power in a Mustang. He provides detailed diagnostics using a voltmeter
, and has an awesome cutaway of a vehicle battery and even the internal battery plates to show viewers exactly what a crumpled mess it looks like when they begin to fail. Sure, most of us who know about cars understand why batteries fail and how to prolong their lives and replace them, but it’s not often we see the inside of one that has failed to add to our understanding or that we receive an education about volts, amps and resistance.
Gardner employs a similar tactic with the full-scale working model of a starting system. He even has a couple starters
– including a big field-coil starter – that he’s taken apart to show viewers how they work and why. On this episode, the biggest moment of drama between people is when Gardner asks his assistant to crank the Mustang with the headlights on, and it fails to start. As I said, if you’re looking for fights and name calling, you’re going to find them on this car TV show.
Watch and learn
In addition to adding to your knowledge under the hood, Tech Garage
provides some pretty cool factoids in every episode that can be used to impress your friends, or one-up a fellow heavy DIYer who always seems to be a step ahead. Try these on for size. What was the first production vehicle to use an alternator? That would be the 1960 Chrysler Valiant. How about the fact that the first storage battery, called the voltaic pile, was invented in 1796 by Italian scientist Allesandro Volta? The volt is named in his honor. And finally, 99 percent of all new cars sold have air conditioning.
On another episode, Gardner dives into a timely topic now that temperatures are starting to rise–a vehicle’s AC system. In addition to demonstrating how it works and how to quickly and easily recharge it using a canister of AC Pro
, and how to identify the high side versus the low side, he has a full scale vehicle AC system, complete with condenser
. And it’s functioning. If you walk away not understanding more about vehicle AC and how the AC cycle works, you weren’t watching.
With insightful and timely show topics that include brakes and wheel bearings, fuel systems and turbo and supercharging, and engines and related emerging technologies, Tech Garage
should quickly build a following of loyal viewers who want to learn vehicle mechanics from an ASE-certified pro.
