Lang Tools Diesel Compression Tester (TU-15C)

Description

The Lang Tools Diesel Compression Tester (TU-15C) is an essential tool for accurately assessing the internal health of diesel engines in both cars and trucks. This specialized instrument is designed to measure the pressure within engine cylinders, providing crucial data for diagnosing a range of performance issues. Whether you’re a professional mechanic or a dedicated DIY enthusiast, the TU-15C offers a precise and efficient method to identify problems such as worn piston rings, leaky valves, or compromised head gaskets, all of which can severely impact engine power and efficiency. Its robust construction ensures reliability, making it a valuable addition to any automotive toolkit focused on diesel vehicle maintenance and repair.

KEY FEATURES AND BENEFITS:

• Accurate Pressure Measurement: Features a 2 1/4″ gauge with a dual-scale dial, clearly displaying readings from 0 to 1000 psi and 0 to 70 bar, allowing for precise assessment of cylinder pressure in various diesel engines.
• Efficient Testing: Equipped with a handy deflator button that releases air, enabling automatic resetting of the gauge for quick and seamless repeat testing without the need to disconnect the tool.
• Broad Compatibility: Includes a swivel-end quick coupler designed for easy and secure connection to a wide range of adapters, ensuring versatility across numerous diesel engine makes and models, including GM, Ford, Isuzu, Mercedes, Toyota, VW, and more.
• Extended Reach and Durability: Comes with a 16 1/2″ (or 355 mm) wire-reinforced hydraulic hose, providing sufficient reach to access cylinders in various engine configurations while ensuring long-term durability and resistance to wear.
• Engine Health Diagnostics: Helps identify critical engine problems such as worn piston rings, burnt or sticky valves, and head gasket leaks by accurately measuring compression, guiding effective repair strategies.

SPECIFICATIONS:

• Gauge Diameter: 2 1/4″
• Pressure Range: 0 – 1000 psi and 0 – 70 bar
• Hose Length: 16 1/2″ (355 mm)
• Hose Type: Wire-reinforced hydraulic
• Coupler Type: Swivel-end Quick Coupler

HOW TO USE:

1. Prepare the Engine: Ensure the engine is cool. Disconnect the fuel injection system to prevent fuel delivery during testing. Remove all glow plugs or injectors from the cylinders.
2. Connect the Tester: Select the appropriate adapter for the engine you are testing. Attach the adapter to the cylinder opening. Connect the swivel-end quick coupler of the Lang Tools TU-15C tester firmly to the adapter.
3. Perform the Test: Crank the engine for several revolutions (usually 5-10 seconds) until the gauge registers a stable maximum reading. Note down the compression reading for that cylinder.
4. Reset and Repeat: Press the deflator button on the gauge to release the air and reset the needle to zero. Disconnect the tester from the adapter and move to the next cylinder. Repeat the process for all remaining cylinders.
5. Analyze Readings: Compare the readings from all cylinders. Significant variations (typically more than 10-15%) between cylinders or readings below the manufacturer’s specifications indicate an engine problem.
