Lincoln MV4560 Cooling System Pressure Tester Kit

Product Description

The LINCOLN MV4560 is a cooling system pressure tester kit used to locate leaks in automotive and light-duty cooling systems. By pressurizing the cooling system without running the engine, technicians can identify failed hoses, cracked radiators, leaking water pumps, and degraded gaskets that would otherwise be difficult to pinpoint. The kit includes a hand pump, adapters, hose, and clamp for a total of 9 pieces. It is designed for use by automotive technicians, fleet service professionals, and skilled DIYers who need a reliable, non-destructive method for diagnosing coolant loss.

This tester is suited for shops handling routine maintenance, overheating complaints, or pre-purchase inspections on passenger vehicles and light trucks. The adapter set allows the tester to fit a range of radiator and coolant reservoir cap sizes, making it versatile across different makes. The pump and hose assembly builds pressure in the system so leaks show themselves without the vehicle needing to reach operating temperature, keeping service time efficient and reducing the risk of burns from hot coolant.

Key Features

• Pressurizes cooling system to reveal leaks in hoses, radiators, water pumps, and gaskets
• Includes hand pump, adapters, hose, and clamp for a complete 9-piece kit
• Adapter variety supports multiple radiator and coolant reservoir cap configurations
• Cold-system testing reduces burn risk during diagnosis
• Compact kit dimensions support toolbox and service van storage

Compatibility

Designed as a general-purpose cooling system pressure tester for use on passenger vehicles and light-duty trucks with standard radiator cap and coolant reservoir cap fittings. Verify adapter fitment against the specific vehicle before use.

Installation Notes

Allow the engine and cooling system to cool completely before connecting the tester to avoid scalding from pressurized hot coolant. Remove the radiator or reservoir cap, select the correct adapter from the kit, and attach the pump assembly according to the kit instructions before applying pressure. Do not exceed the system pressure rating marked on the vehicle radiator cap or printed in the service manual. This tool is typically used by automotive technicians but is accessible to knowledgeable DIYers familiar with cooling system service.
