Preparation

1. Park vehicle on level surface and allow engine to cool completely (minimum 2 hours)
2. Disconnect negative battery cable
3. Raise vehicle and support securely on jack stands
4. Remove plastic engine undercover and splash shields
5. Place drain pan under oil drain plug

Procedure

1. 1

   Drain engine oil
   Remove oil drain plug and allow all engine oil to drain completely into drain pan. Remove oil filter and allow additional oil to drain. Install new crush washer on drain plug and reinstall drain plug to specified torque.

2. 2

   Remove front exhaust pipe
   Disconnect oxygen sensor connector. Remove exhaust pipe mounting bolts from exhaust manifold and from catalytic converter bracket. Support exhaust and carefully lower front section away from engine to provide clearance for oil pan removal.

3. 3

   Install engine support
   Install engine support fixture across engine bay or use an engine support bar. Attach lifting chain or hook to engine lifting eye. Apply slight upward tension to support engine weight before removing motor mount.
   ⚠️Engine must be properly supported before proceeding. Verify support is secure and engine is stable.
4. 4

   Remove front engine mount
   Remove lower mounting bolts securing front engine mount to subframe. Remove upper mounting bolts securing mount to engine. Carefully remove engine mount assembly. Raise engine slightly using support fixture to gain additional clearance for oil pan removal (approximately 25-50mm).

5. 5

   Disconnect oil level sensor
   Locate oil level sensor on oil pan. Disconnect electrical connector by pressing release tab and pulling connector straight off. Move wiring harness aside to prevent damage during pan removal.
6. 6

   Remove oil pan bolts
   Working in a cross pattern from outside toward center, gradually loosen all oil pan bolts. Remove all bolts completely and set aside. Note location of any different length bolts for proper reinstallation.
7. 7

   Remove oil pan
   Carefully tap oil pan with rubber mallet to break gasket seal. If pan is stuck, use plastic pry tool at designated pry points only - do not pry on gasket sealing surfaces. Once seal is broken, carefully lower oil pan and maneuver out from between engine and subframe. Allow any remaining oil to drain.
   ⚠Do not use metal tools or pry on sealing surfaces as this will damage mating surfaces and cause leaks.
8. 8

   Inspect and remove oil pump pickup tube
   With oil pan removed, inspect oil pump pickup tube screen for debris or damage. Remove pickup tube mounting bolts and lower pickup tube from oil pump. Clean pickup tube screen thoroughly or replace if damaged.

9. 9

   Clean all mating surfaces
   Use plastic scraper to carefully remove all old gasket material from oil pan and engine block sealing surfaces. Clean surfaces with brake cleaner and lint-free cloth. Ensure surfaces are completely clean, dry, and free of oil residue. Use wire brush on pickup tube mounting area if needed.
   ⚠Mating surfaces must be perfectly clean and smooth. Any scratches, gouges, or remaining gasket material will cause oil leaks.
10. 10

    Reinstall oil pump pickup tube
    Position oil pump pickup tube to oil pump. Install mounting bolts and tighten to specified torque. Ensure pickup tube screen is positioned correctly and not touching bottom of oil pan when installed.

11. 11

    Prepare and install new oil pan gasket
    If using gasket, apply thin continuous bead of RTV silicone (3mm) to oil pan groove, circling all bolt holes. If using RTV only method, apply 3-4mm bead to engine block sealing surface. Pay special attention to corners and front/rear main seal areas - apply slightly larger bead at these points. Position new gasket or prepare pan immediately.
    ℹ️RTV must be applied and pan installed within 5-10 minutes before sealant begins to cure. Work quickly but carefully.
12. 12

    Install oil pan
    Carefully lift oil pan into position, maneuvering between subframe and engine block. Align all bolt holes. Start all oil pan bolts by hand, ensuring they thread properly without cross-threading. Tighten oil pan bolts in sequence from center outward in multiple passes (first pass 50%, second pass 75%, final pass to full torque) to ensure even gasket compression.

    Reinstall engine mount and lower engine
    Position front engine mount between engine and subframe. Install and hand-tighten all mounting bolts. Lower engine slowly using support fixture until weight rests on mount. Tighten upper and lower mounting bolts to specified torque. Remove engine support fixture.

    Reinstall exhaust and accessories
    Raise front exhaust pipe into position. Install exhaust mounting bolts and tighten to specified torque. Reconnect oxygen sensor electrical connector. Reconnect oil level sensor electrical connector.

    Refill engine oil and check for leaks
    Install new oil filter and tighten by hand plus 3/4 turn. Refill engine with 4.5 quarts of Kia Genuine 5W-20 engine oil. Reinstall engine undercovers and splash shields. Reconnect negative battery cable. Start engine and check oil pressure warning light extinguishes. Allow engine to idle for 2-3 minutes while carefully inspecting oil pan gasket area for leaks. Shut off engine, wait 5 minutes, then recheck oil level and top off if necessary.
    ℹ️Do not run engine at high RPM for first 30 minutes to allow RTV sealant to fully cure.

Reassembly

1. Allow RTV sealant to cure for minimum 1 hour before filling with oil, 24 hours for full cure
2. Torque all fasteners to specification in proper sequence
3. Verify all electrical connectors are properly seated and secured
4. Double-check oil level after test drive and allow vehicle to sit for proper reading

Verification

• Start engine and verify oil pressure warning light extinguishes within 2-3 seconds
• With engine running, inspect entire oil pan gasket perimeter for any signs of leakage
• Check oil level on dipstick after engine reaches operating temperature and has been shut off for 5 minutes
• Test drive vehicle and recheck for leaks after engine reaches full operating temperature
• After 24 hours and 50-100 miles of driving, perform final leak inspection and recheck oil level
