This procedure covers removal and replacement of the engine oil cooler assembly on the 2012-2017 Toyota Camry 2.5L I4 engine, including coolant drainage, oil cooler housing removal, and system refill.

Warnings

Tools required

Parts

• Engine oil cooler assembly × 1 — Use OEM specification
• Oil cooler housing gasket × 1 — Use OEM specification
• Oil filter × 1 — Use OEM specification
• Drain plug washer × 1 — Use OEM specification

Fluids

• Toyota Genuine 0W-20 — 5 qt
• Toyota Super Long Life Coolant (Pink) — 3 qt

Preparation

1. Ensure engine is completely cold to the touch
2. Park vehicle on level surface and engage parking brake
3. Raise and support front of vehicle on jack stands at manufacturer lift points
4. Remove engine splash shield using 10mm socket
5. Place large drain pan under engine oil drain plug and oil filter area

Procedure

1. 1

   Drain engine coolant
   Locate the coolant drain plug on the bottom of the radiator on the driver's side. Place drain pan beneath the plug and open slowly. Allow coolant to drain completely. Remove radiator cap to speed draining process once initial pressure is released.
   Torque spec

   Coolant Drain Plug15 Nm (11 lb-ft)
2. 2

   Drain engine oil
   Remove the engine oil drain plug using 14mm socket and allow oil to drain completely into drain pan. Inspect drain plug washer and replace if damaged. Set drain plug aside with new washer for reinstallation.
3. 3

   Remove oil filter
   Using oil filter wrench, remove the oil filter by turning counterclockwise. Allow residual oil to drain. The oil cooler is located directly behind where the oil filter mounts.
   ℹ️Expect additional oil spillage when removing filter. Position drain pan accordingly.
4. 4

   Disconnect coolant hoses from oil cooler
   Locate the two coolant hoses connected to the oil cooler housing below the oil filter mounting surface. Using flathead screwdriver or pliers, release the hose clamps and slide them back along the hoses. Carefully twist and pull hoses off the oil cooler fittings. Expect residual coolant drainage.
   Torque spec

   Hose Clamps3 Nm (2 lb-ft)
5. 5

   Remove oil cooler mounting bolts
   Locate the mounting bolts securing the oil cooler housing to the engine block. There are typically 2-3 bolts accessible from below. Remove these bolts using 10mm socket. Support the oil cooler housing as you remove the final bolt.
   ⚠Oil cooler housing may be stuck due to gasket seal. Do not pry against machined sealing surfaces.
   Torque spec

   Housing Bolts14 Nm (10 lb-ft)
6. 6

   Remove oil cooler assembly
   Carefully pull the oil cooler assembly away from the engine block. If stuck, gently twist while pulling. Remove old gasket material from both the oil cooler housing and engine block mounting surface using a plastic scraper. Do not use metal scrapers on machined aluminum surfaces. Clean surfaces thoroughly with shop towels.
   ⚠Do not scratch or gouge the sealing surfaces on the engine block or oil cooler housing as this will cause leaks.
7. 7

   Inspect and prepare new oil cooler
   Inspect new oil cooler assembly for shipping damage. Verify gasket is properly positioned on new oil cooler housing. Lightly coat gasket with clean engine oil to aid installation and prevent tearing during assembly.
8. 8

   Install new oil cooler assembly
   Align new oil cooler assembly with mounting holes on engine block. Carefully press housing into position, ensuring gasket seats evenly. Thread mounting bolts by hand first to prevent cross-threading. Tighten bolts to specification using torque wrench in a cross-pattern if multiple bolts.
   Torque spec

   Housing Bolts14 Nm (10 lb-ft)
9. 9

   Reconnect coolant hoses
   Push coolant hoses firmly onto oil cooler fittings until fully seated. Slide hose clamps into position over the hose-to-fitting connection area. Tighten hose clamps to specification using appropriate tool. Ensure clamps are positioned correctly and hoses are fully seated.
   Torque spec

   Hose Clamps3 Nm (2 lb-ft)
10. 10

    Install new oil filter
    Apply thin film of clean engine oil to the rubber gasket of the new oil filter. Thread oil filter onto mounting post by hand, turning clockwise. Tighten oil filter by hand only until gasket contacts the mounting surface, then turn an additional 3/4 turn. Do not use oil filter wrench for installation.
11. 11

    Reinstall drain plugs and refill fluids
    Install coolant drain plug with new washer and tighten to specification. Install oil drain plug with new washer and tighten to specification (typically 30 Nm but verify in owner's manual). Fill engine with 5.0 quarts of Toyota Genuine 0W-20 oil. Fill cooling system with Toyota Super Long Life Coolant (Pink) through radiator cap opening.
    ℹ️Cooling system may require bleeding to remove air pockets. Consult cooling system bleeding procedure if equipped with bleed valve.

    Check for leaks and verify operation
    Start engine and allow to idle. Immediately check oil cooler, oil filter, and coolant hose connections for leaks. Monitor coolant level and add as needed while engine warms up and thermostat opens. Check oil level on dipstick once engine reaches operating temperature and add oil if needed.
    ⚠Shut off engine immediately if oil pressure warning light remains illuminated or if significant leaks are observed.

Reassembly

1. Reinstall engine splash shield and tighten fasteners securely
2. Lower vehicle from jack stands
3. Top off coolant reservoir to FULL mark after engine cools
4. Verify oil level is between MIN and MAX marks on dipstick when cold

Verification

• Start engine and verify no warning lights are illuminated on instrument cluster
• Check all connection points for coolant and oil leaks while engine is running
• Allow engine to reach full operating temperature and verify cooling fan cycles normally
• Re-check oil and coolant levels after test drive and top off if necessary
• Monitor oil and coolant levels over the next few days to ensure no slow leaks are present
