UView Cooling System Tester

UView Cooling System Testers: Precision Diagnostics for Every Leak

When a vehicle's cooling system fails, the consequences range from a simple topping-off job to a catastrophic engine repair. Finding the problem quickly and accurately is what separates a confident technician from a guessing game — and that's precisely where UView has built its reputation. As a recognized leader in automotive fluid-system diagnostics, UView brings engineering-driven solutions to one of the most important maintenance categories in the shop: cooling system testing.

Two Distinct Tools, One Focused Mission

UView's cooling system tester lineup centers on two purpose-built instruments that tackle the problem from different angles, giving technicians the right tool for the right diagnosis.

• UView Airlift™ Cooling System Leak Checker & Airlock Purge Tool (550000): This kit simplifies the process of refilling and testing a vehicle's cooling system, and is designed for efficiency — eliminating time-consuming bleeding and purging by refilling the entire system using vacuum pressure. It is an OEM-approved tool that does away with time-consuming purging , making it a staple in professional shops. It works on cars, trucks, and off-road vehicles , offering broad vehicle coverage from a single kit.
• UView Combustion Leak Tester (560000): This tool provides a fast, economical, and accurate method to test for combustion gas leaks from head gasket leaks, cylinder head leaks, and engine block leaks. What sets it apart from simpler alternatives is its engineering approach to accuracy. The tester features a dual-chamber design for higher accuracy to eliminate false readings — the first chamber filters out any alkaline particles that could result in a false indication of a combustion leak. This two-stage approach means technicians can trust their results before recommending expensive repairs like a head gasket replacement.

Why UView Stands Out in Cooling System Diagnostics

UView is one of the industry leaders in the manufacture of a variety of shop tools and equipment, with a product portfolio that includes different types of leak testers, radiator tools, coolant exchangers, and fill hose assemblies. In the cooling system space specifically, UView distinguishes itself through a vacuum-based methodology that addresses two of the most common shop headaches simultaneously: detecting leaks and eliminating airlocks during refill.

Compressed air powers the Vacufill technology, enabling fast, efficient, and low-cost operation, while the built-in vacuum system checks the system for any potential leaks — all in one connected workflow. The system is equipped with a variety of adapters that eliminate the need to cut or disconnect the vehicle hose , reducing the risk of collateral damage during the diagnostic process.

Confidence Before Costly Repairs

The dual-chamber combustion leak tester in particular addresses a critical concern: false positives. Although not the cheapest way to find a head gasket leak, it is pretty much the only way to definitively confirm you do not have a leak. For any shop that values accuracy over assumptions, UView's approach to cooling system testing — whether vacuum-based refilling or hydrocarbon combustion detection — provides the reliability professionals depend on.
