Oil Cooler Flow Check

  1. With transmission fluid filled to proper level, disconnect oil cooler return line at transaxle. See Figure . Place container under oil cooler return line.
    CAUTION: Do not obtain more than one quart of fluid, or transaxle may be damaged.
  2. Apply parking brake. Start engine and allow it to idle. Place gearshift lever in Neutral. Check fluid flow from oil cooler return line.
  3. If fluid flow is consistent and takes 20 seconds or less to obtain one quart, oil pump volume and oil cooler flow are okay. If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, disconnect oil cooler inlet line. Refill transaxle to proper level and recheck flow.
  4. If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, check line pressure. See PERFORMANCE TESTS in appropriate DIAGNOSIS article. If fluid flow is consistent and takes 20 seconds or less to obtain one quart, replace oil cooler. Reconnect oil cooler lines. Fill transaxle with appropriate fluid to proper level.
