Coolant Pressure Testing Specs
If you have a radiator pressure tester, the appropriate adapter should come with the kit. The adapter is attached to your coolant fill reservoir - either a spin on or a conventional radiator cap lock-down with tabs. If your pressure tester doesn't come with the adapter kit, perhaps your local auto parts shop has loaner/rent adapters. Take a photo of the coolant tank w/o the cap and bring it down to the parts store.
"Cooling system pressure tests:
- Maximum test pressure: 1.5 bar (21.7 psi) - Exceeding the specified test pressure could damage radiator or cooling system.
- Maximum pressure drop: 0.1 bar (1.5 psi) after 2 minutes
On screw on type caps, the expansion tank cap opening pressure is molded onto the top of the cap.
On screw-on type caps, check the vacuum valve on the back of the cap by lifting up on the valve. The vaccum valve should spring back into position on its seat. Inspect the cap's gasket. A faulty cap or damaged cap gasket should be replaced." Bentley Manual Cooling System Section 5- Joe
