Description

Compatible with Focus Fiesta Mazada Ford 1.5 1.6 VCT Ecoboost Engine Quickly and easily diagnose ignition or engine outboard motor problems and fuel delivery system failures The founder of AutoWanderer Tool was a workman of a machining factory. Our aim is to offer automotive tool sets for technicians and enthusiasts who need to keep any motor vehicle in peak condition. So we constantly improve process engineering and technology to test our tools, now we are able to develop a wide range of automotive tools. -- Ideal for a wide range of applications on many Petrol Gas engine cylinders for most spark plug types on cars, trucks, motorcycles, lawn mowers & more. It's definitely value for money! You'll able to get a fairly wide range of functions. NOTE: Please always release the pressure and reset the gauge before disconnecting the compression test. Ensure that the cylinder pressure does not exceed the maximum range of the gauge. Not for most diesel engine, due to the low pressure range 0-300PSI. MAINTENANCE: OPERATION 1. After the engine is running to normal temperature, stop the engine and disconnect all spark plug wires, clean all spark plug wells. 2. Remove the air filter and set the throttle plates to the wide open position. 3. Disconnect the ignition system and install the push-on connector , or screw the assembled hose into the spark plug hole. (Hand tighten only, DO NOT use a wrench, DO NOT over tighten) Then connect the gauge by the quick connector. Make sure all connections are fully engaged. 4. Crank the engine for at least 5 compression strokes until the pressure reading no longer changes. Record the pressure reading, then press the button (release valve) to relieve the pressure. 5. Repeat the above steps and measure each cylinder 2 to 3 times to ensure measurement accuracy. Don't forget to reset the gauges and crank the engine each time. The removed parts should be put back in place after the operation, especially before engine running. Rubber cones ends for quick check (no need to thread into head) without any need for threading

Size: Gauge Set without Spark Plug Tester
Function well, quality looks fare, product is accurate as shown in picture, Good price, adapters fits well, will take some time to speak about the reliability, but it is easy to read the gauge.

  • Compression tester = good, spark tester = bad
Size: Gauge Set with Spark Plug Tester
The compression tester worked perfect for my small engine projects. It even has a valve at the end of the tube which makes it compatible with small engines. The spark tester was pretty bad. The probe and pulled out of the plastic and the only thing holding it in place was the teeth on it, which were plastic. I have used this compression tester over 15 times with no trouble at all. I don’t find myself using the spark tester since it comes apart so easy. ... show more

  • My first ever compression tester, it works great!
Size: Gauge Set without Spark Plug Tester
The media could not be loaded. So far it seems to work very well for diagnosing my older machines, so far the gauge is very readable and it doesn't seem to leak and fits well, durability wise I have no idea how long it's going to last but so long as I put it back in the case it should be good for many years to come, all in all it seems like a very durable little unit and holds pressure fine ... show more
