Radiator Inspection Manual

Product Overview

This manual provides detailed instructions for inspecting and testing radiators to ensure they are free from air and water leakage. It covers procedures for using a radiator tester, measuring pressure drop, and conducting leak tests.

Key Features

• Comprehensive Inspection Guide: Step-by-step instructions for inspecting and testing radiator integrity.
• Pressure Testing: Methods for applying and measuring pressure to detect potential leakages.
• Repair Guidelines: Advice on how to address common issues such as pinhole leaks.

Benefits

• Ensure Longevity: Regular inspection can prevent costly damage and extend the life of the radiator.
• Maintain Efficiency: Properly functioning radiators contribute to optimal engine performance.
• Safety Assurance: Identifying and repairing leaks can prevent overheating and potential engine failures.

Usage Recommendations

• Use a radiator tester and appropriate adapter to check pressure levels accurately.
• Follow the specified pressure guidelines: apply 88 kPa (13 psi) and measure the time for pressure to fall to 59 kPa (8.6 psi).
• If pressure drops quicker than the factory specification (more than 10 seconds for pressure fall from 88 to 59 kPa), replace the radiator cap.
• For water leakage: pour the specified amount of water, test with the specified pressure, and check for leaks.
• Repair minor leaks using radiator cement; if leakage is excessive, replace the radiator.
• Always refer to individual radiator specifications during leak testing, as pressure requirements may vary.

Manual Extract: Radiator – Inspect for Air & Water Leakage

1. Set a radiator tester (1) and an adaptor (2) on the radiator cap.

2. Apply the specified pressure 88 kPa (13 psi), and measure the time for the pressure to fall to 59 kPa (8.6 psi).

3. If the measurement is less than the factory specification, replace the radiator cap.

Pressure Falling Time	Factory Specification
More than 10 s for pressure fall 88 u2013 59 kPa (13 u2013 8.6 psi)

Water Leakage

1. Pour a specified amount of water into the radiator.

2. Set a radiator tester (1) and an adaptor (2) and raise the water pressure to the specified pressure.

3. Check the radiator for water leaks.

4. For water leak from the pinhole, repair with the radiator cement. If water leakage is excessive, replace the radiator.

Note: The pressure of the leak test differs according to each radiator specification. Please refer to the test pressure specific to each radiator.
