This procedure covers the removal and replacement of the power steering fluid reservoir on a 2014-2019 Toyota Corolla with the 1.8L I4 engine.

Warnings

Tools required

Parts

• Power steering reservoir × 1 — Use OEM specification
• Power steering line O-rings × 2 — Use OEM specification
• Reservoir cap with filter screen (if damaged) × 1 — Use OEM specification

Fluids

• Toyota ATF Dexron III — 1 qt

Preparation

1. Park vehicle on level ground and set parking brake
2. Allow engine to cool completely
3. Place drain pan beneath work area
4. Remove engine cover by pulling upward on the front edge, then lifting off

Procedure

1. 1

   Remove fluid from reservoir
   Use a turkey baster or fluid pump to remove as much power steering fluid as possible from the reservoir. This minimizes spillage during removal. Dispose of old fluid properly.
2. 2

   Disconnect return hose
   Locate the lower return hose on the bottom of the reservoir. Use pliers to squeeze and slide the spring clamp away from the reservoir fitting. Twist and pull the hose off the reservoir nipple. Allow remaining fluid to drain into the pan.
3. 3

   Disconnect pressure line
   Using a 12mm wrench, loosen and disconnect the metal pressure line fitting from the side of the reservoir. Be prepared for fluid spillage. Plug the line opening with a clean shop towel to prevent contamination.

4. 4

   Remove reservoir mounting
   Remove the two 10mm mounting bolts securing the reservoir to its bracket on the engine compartment. Support the reservoir while removing the second bolt to prevent it from falling.
   Torque spec

   Mounting Bolts26 Nm (19 lb-ft)
5. 5

   Remove reservoir
   Carefully lift the reservoir up and out of the engine compartment. Keep it upright to minimize fluid spillage. Inspect the old reservoir for cracks, leaks, or damage to the mounting points.
6. 6

   Prepare new reservoir
   Transfer the cap and screen assembly to the new reservoir if it is not included. Install new O-rings on both the pressure line fitting and return hose nipple. Lightly lubricate O-rings with fresh power steering fluid.
7. 7

   Install new reservoir
   Position the new reservoir into the mounting bracket. Install both mounting bolts finger-tight first to ensure proper alignment, then torque to specification.

8. 8

   Connect pressure line
   Remove the protective plug from the pressure line. Thread the pressure line fitting into the reservoir by hand to avoid cross-threading. Torque to specification using a 12mm wrench.

9. 9

   Connect return hose
   Push the return hose firmly onto the reservoir nipple until it seats completely. Slide the spring clamp back into position over the hose connection. Ensure the clamp is positioned properly over the hose bead.
10. 10

    Fill and bleed system
    Fill the reservoir with Toyota ATF Dexron III to the cold fill line. Start the engine and turn the steering wheel lock-to-lock several times slowly. Check fluid level and add as needed. Continue until no air bubbles appear in the reservoir and fluid level stabilizes.

Reassembly

1. Reinstall engine cover by aligning rear tabs and pressing down until front clips engage
2. Check all connections for leaks with engine running
3. Top off power steering fluid to cold fill line after system reaches operating temperature

Verification

• Check for fluid leaks at reservoir connections with engine running and cold
• Turn steering wheel lock-to-lock and verify smooth operation without noise
• Verify fluid level is at the appropriate cold or hot line depending on engine temperature
• Test drive vehicle and confirm normal power steering assist and no unusual noises
• Recheck fluid level after test drive and top off if necessary
