Diesel Engine Compression Tester Kit with Hydraulic Gauge Glow Plug Injector Adapters

This big set for testing diesel engine compression pressure with several adapters is definitely worth it. To begin with, the gauge has a big pressure range, from 0 to 70 bar, or 0 to 1000 psi. When you take a closer look, you might see that there is fluid filled inside the gauge, and that's glycol. The purpose of filling this fluid in the gauge is to protect the gauge reader. In some cases, when the diesel engine compression pressure is very high, the gauge reader may be damaged by a sudden jump, so the glycol is able to slow down the pace for the reader to go up. As you can see in the instruction video below, the reader goes up slowly just like you are watching a second needle ticking on a traditional clock. The gauge has a rubber boot that can also protect the gauge in case that the gauge falls to the ground, and the rubber boot gives a sturdy and robust hand held feeling. Of course, do not forget to release the pressure once the compression pressure test is done. 

The small case in this big set is a universal adapter for diesel engine injectors. The rings and attachments in the small case can be inserted into the central shaft. Once you remove the diesel injector, try to mimic the injector's shape with the rings and attachments, and finally make a comparison to make sure that the shapes are similar. There are also seat holders provided in the small case that can fit onto the injector to the engine with the original bolts from the engine. 

On some occasions, the diesel injectors are seriously stuck because of the carbon buildup and removing the injectors may break or create minor damages to the injectors. You may want to remove the glow plugs as an alternative way to get access to the combustion chamber. This big set includes 22 glow plug adapters that literally cover the majority of the diesel engines on the market. Simply screw the glow plug adapter into the engine and connect the quick coupler on the gauge and we can proceed to the next step. 

Each engine compartment has different configurations, and the glow plugs may be situated on the sides of the engine and that may create a space problem when we try to hook up the gauge to the glow plug adapters. Thus, a 90 degree adapter is included in this big set so you may still be able to get every part connected even in an engine bay with limited access. 

Once all parts are securely connected, remove the fuel pump relay before turning on the engine. We just want to check the compression pressure, but we don't want to actually test the explosion inside the combustion chamber. Let the engine run for a few seconds, and the pressure will slowly build up and can be read on the gauge. Check the automotive manufacturer's service manual for the standard compression pressure values, and take the proper steps as suggested by the service manual if incorrect compression pressure values are found.
