"  Q: First off, I really enjoy reading your Auto Clinic every month. Always good info there, I just hope I can remember it all! In the April 2010 issue you show a picture of a Gates Belt gauge and mention it&amp;#039;s available on their website, I did several searches there and couldn&amp;#039;t find anything that looked like that. Oh wait! Was that an April Fool&amp;#039;s joke? If so, you got me.... If not, what&amp;#039;s the part number? A: Yeah, they moved it off the home page after we went to press. You can find it here: Gates Belt gauge Q: For years I used an analog stick style tire gauge and never thought anything about it. A while back I read a recommendation (probably in Popular Mechanics) that a &amp;quot;good quality&amp;quot; tire gauge should be used, so I went to a reliable auto parts store and purchased a more expensive gauge that they recommended. This one works quite well and is accurate from one reading to the next. What I have noticed is that it and the gauge used at the local tire shop do not match. My gauge is always about 2 pounds lower. Where does one purchase a &amp;quot;good quality&amp;quot; tire gauge and how can the accuracy be checked? A: I must have 6 tire gauges, from pencil gauges to expensive liquid-filled gauges that can check two tires at the same time. I keep one, a $30 liquid-filled gauge in the toolbox along with the micrometers, dial indicators and other expensive fragile stuff, and use it to calibrate other gauges periodically. Everyday, I find most gauges within a couple of pounds of that one. Just add two pounds to your gauge&amp;#039;s reading. Q: What scan tool do you prefer at your shop? I have a Snapon Modis with all of the databases and optional pieces/parts, and like it very much. I&amp;#039;d just be interested in your particular choice. A: I have a passing familiarity with pro-grade scan tools, including the Snap-On. I don&amp;#039;t repair cars full-time anymore, and most of our readers are hobbyists, not pro mechanics. Consequently, it&amp;#039;s tough to justify the huge expenditure for a pro-grade tool, like the nearly eight grand (!) the Modis carries. I have several consumer-grade machines, including ones from Auto X-Ray, Actron and Equus. They all have their benefits. I usually reach for the Equus first, however. I just priced one online for $227. The big advantage to a pro-grade machine is the support from the manufacturer. If I still made a living fixing cars full-time, I&amp;#039;d probably spring for one, but I&amp;#039;m not really in a position to recommend one today because I don&amp;#039;t use them consistently.
