Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pump Flow Test
Operate engine at idle speed until reservoir fluid temperature reaches 165-175°F and maintain this temperature throughout tests (Valve B may be partially closed to create a back pressure up to 350 psi to hasten fluid warm-up). With engine idling and fluid temperature correct, close valve "B" and note gauge reading. If gauge reading is below minimum shown below, pump is defective and should be repaired.
| Ford, Mercury, Meteor | 620 psi |
| Lincoln, Continental Mark III & IV, Thunderbird | 900 psi |
