Checking pressure regulator, pressure increase

WARNING: This page is about a different car, the 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

Connect pressure tester 9985496 and pressure gauge 9995230 to pressure regulator.
Pump up pressure.
- Check that line pressure rises by the same amount as the pressure in the regulator.
- 300 kpa + overpressure = line pressure.
- Disconnect hose from pressure tester.

Line pressure should return to 300 kPa.

OK
