Seven must- have car diagnostic tools

An Obd2 scanner is a diagnostic system that allows onboard computers in cars and trucks to tell you what’s wrong with the vehicle. This car diagnostic tool is used for a range of self-diagnostic and reporting purposes. Unlike the earlier, OBD-I system, the Obd2 system uses the same code designations, communication protocols, and connectors for cars made by all major manufacturers. The standardization has made the previous Obd1 almost completely obsolete.

A vacuum test is among the simplest Car Diagnostic Tools a mechanic can have. With a simple gauge, anyone can gain valuable insight into vacuum leaks, low compression, incorrect timing, and sticking valves just to name a few. You will need to know the vacuum specifications for your engine, and bear in mind that these gauges are adjusted for sea level. That means for every 1,000 feet your location is above sea level, you will need to subtract an inch of vacuum. The simplest check to perform is a running vacuum test. Simply start the engine and let it reach normal operating temperature. Find a vacuum port and connect the gauge. The port should be on the manifold or below the carburetor. It shouldn’t be on the air cleaner, high on top of the carburetor, or on any of the emissions control components.
