Pump Pressure Check

  1. Check fluid level and belt tension. Adjust as necessary. Disconnect outlet hose from pump. Install Pump Joint Adapter (07NAK-SR3011A on Integra, 07QAK-POA0110 on 2.3CL, 07GAK-SE00112 on 3.5RL) onto pump outlet fitting. See Fig 1. On 3.0CL, install Pump Joint Adapter (07VAK-P8A011A) with Adapter Plate (07VAK-P8A012A) onto pump outlet fitting.
  2. Install Hose Joint Adapter (07NAK-SSR3012A on Integra, 07QAK-POA0120 on 2.3CL, 07RAK-SO40121 on 3.0CL, 07GAK-SE00120 on 3.5RL & 3.2TL, or 07QAK-PV30120 on 2.5TL) onto outlet hose. Install Pressure Gauge Set (07406-0010001) between pump and hose joint adapters. Fully open shutoff and pressure control valves.
  3. Start and idle engine. Turn steering wheel lock to lock several times to warm fluid. Completely close shutoff valve.
  4. Gradually close pressure control valve until pressure gauge needle stabilizes. Read pressure. Immediately open shutoff valve. Pump pressure should be at least 924psi (65kg/cm2 ) for Integra and 2.3CL, 1090 psi (76.5 kg/cm2 ) for 3.0CL, or 1140 psi (80 kg/cm2 ) for 3.5RL. Repair or replace pump if pressure is not within specification.
CAUTION: To prevent damage to pump, DO NOT keep shutoff valve closed for longer than 5 seconds.
