The OTC Universal Cooling System Pressure Test Kit is designed to eliminate the search for the right coolant cap adapter.
The tester features four adapters (1/4, 5/16, 1/2 and 5/8 in.) with Schrader valves to prevent coolant spray when disconnecting, while the hand pump includes an easy-to-read integrated pressure gauge and padded base to prevent vehicle surface scratches.
The kit also comes with a dedicated 36” pressure hose with a quick-connect coupler mated to the adapters and a radiator cap adapter for older vehicles.
