Product Information
Full details
This US PRO Tools 19 Piece Coolant System Pressure Tester Kit (MPN 5226) is designed for automotive mechanics and DIY enthusiasts who need to efficiently locate leaks within a vehicle's coolant system. Its primary benefit is the application of air pressure to pinpoint leaks, reducing diagnostic time and guesswork. A potential caveat is that it requires a compatible air source and basic understanding of pressure testing procedures for optimal use. The kit includes a pressure testing pump with gauge, a quick coupler, release valve, a wide array of radiator caps and adaptors for diverse vehicle makes, and a thermostat cap wrench, all housed in a convenient storage case.

FAQs
What is the maximum pressure this kit can safely apply?
The pressure testing pump has a range of 0 - 35 psi. However, it is crucial to consult your vehicle's service manual for the recommended system pressure, which is typically between 15-20 psi. Never exceed the vehicle manufacturer's specified limit.
How do I choose the correct radiator cap adapter?
The kit includes color-coded radiator caps and adapters to simplify selection. Match the adapter or cap size and type to the vehicle's expansion tank or radiator opening. If unsure, consult your vehicle's owner or service manual.
Can this kit be used on all types of vehicles?
The kit is designed for a wide range of domestic and import vehicles. It includes numerous adapters and caps to cover most common applications. However, exceptionally rare or specialized vehicles might require specific adapters not included in this standard kit.
Do I need an air compressor to use this kit?
No, the kit includes its own pressure testing pump. You do not need an external air compressor. The pump allows you to manually build and control the pressure.
How should I clean and store the kit?
After use, wipe down all components with a damp cloth and ensure they are completely dry before placing them back into the storage case. Store the kit in a clean, dry place to prevent corrosion and damage.
What if I can't find a leak?
Ensure all connections are sealed properly. Listen for any audible hissing sounds. Try increasing the pressure slightly if safe to do so, and meticulously check all hoses, connections, the radiator, water pump, and heater core for any signs of coolant weeping or residue.
Troubleshooting
Pump is not building pressure
Check all connections for leaks, including the quick coupler and adapters. Ensure the pressure release valve is fully closed. Inspect the pump's internal seals for damage.
Cannot find a suitable adapter for the vehicle
Refer to the vehicle's service manual for specific coolant system cap sizes. Cross-reference the included adapters with known vehicle models. Consider purchasing additional universal adapters if needed.
Gauge is not accurate or is stuck
Gently tap the gauge face to dislodge any stuck needle. If the issue persists, the gauge may need replacement. Ensure the pump is functioning correctly before testing the gauge.
Leak is still not found after pressurizing
Increase pressure slightly (within safe limits) and listen carefully for hissing sounds. Check all visible hoses, connections, and the radiator for any signs of moisture or staining. Consider that the leak might be very small or internal.
Pros and Cons
Pros
- Effective at pinpointing coolant system leaks.
- Extensive range of adapters and caps for various vehicle types.
- Includes a clear pressure gauge for accurate testing.
- All-in-one kit for convenient storage and transport.
- Facilitates quick coolant system diagnostics.
Cons
- Requires an external air source (compressor or pump).
- May require some mechanical knowledge for proper use.
- The number of adapters may not cover every single vehicle model.
- Color-coding can be subjective and may require cross-referencing.
Setup, Compatibility & Care
Setup:
- Select the appropriate radiator cap or adapter that fits the vehicle's expansion tank or radiator opening. The color-coded caps and adapters are designed to simplify this selection process.
- Connect the pressure testing pump, equipped with the gauge and quick coupler, to the chosen adapter.
- Ensure the pressure release valve is closed.
- Apply air pressure gradually using the pump, monitoring the gauge. Do not exceed the vehicle manufacturer's recommended pressure limit, typically around 15-20 psi, or the tool's maximum of 35 psi.
Compatibility:
This kit is designed for a wide range of domestic and import vehicles. The included 14 radiator caps and 2 specialized adapters cover many common automotive cooling system designs. However, for highly specialized or older vehicles, custom solutions might occasionally be needed.
Care:
- After each use, clean the pump, adapters, and caps with a damp cloth.
- Ensure all components are dry before storing them in the case to prevent corrosion.
- Store the kit in a dry, protected environment.
- Periodically check the gauge and pump for proper function.
