Step-by-Step Guide: How to Perform a 2013 Jeep Wrangler Oil Filter Housing Replacement

Ready to get your hands dirty? This is the core of our how to 2013 jeep wrangler oil filter housing replacement guide. Take your time, follow the steps, and remember safety is always first.

Safety First: Pre-Work Precautions

Disconnect the Battery: Always disconnect the negative battery terminal to prevent accidental shorts or electrical issues.
Engine Cool Down: Ensure the engine is completely cool before starting. You’ll be dealing with hot coolant and oil otherwise.
Secure Vehicle: If lifting the vehicle for better access, use jack stands on a level surface.

Draining the Coolant and Oil

You’ll need to drain both fluids, as the oil filter housing integrates with the cooling system.

Place a drain pan under the radiator. Open the radiator drain cock (petcock) and remove the radiator cap to allow the coolant to flow freely.
Once the coolant is drained, close the petcock.
Move the drain pan under the oil pan. Remove the oil drain plug and allow the engine oil to drain completely.
Replace the oil drain plug and tighten it to specification (usually around 20-25 ft-lbs).

Accessing the Oil Filter Housing

This is the most involved part, as the housing sits under the intake manifold.

Remove the engine cover.
Carefully disconnect the air intake tube from the throttle body and airbox.
Disconnect electrical connectors from the throttle body, MAP sensor, and any other sensors on the intake manifold. Label them if you’re unsure.
Disconnect any vacuum lines or hoses attached to the intake manifold.
Unbolt the throttle body from the intake manifold. You can often leave it connected to its wiring and carefully set it aside.
Remove the intake manifold bolts. There are usually 6-8 bolts. Keep track of their locations, as some might be different lengths.
Carefully lift the intake manifold. You might need to gently pry it up. Be mindful of the fuel lines; you usually don’t need to disconnect them, just lift the manifold enough to clear the engine valley.
Set the intake manifold aside. Cover the intake ports on the engine to prevent debris from falling in.

Removing the Old Housing

With the intake manifold out of the way, the oil filter housing is now visible.

Disconnect the oil pressure sensor and any other electrical connectors on the housing.
Carefully disconnect the two coolant hoses from the oil cooler side of the housing. Be prepared for some residual coolant to spill.
Remove the bolts securing the oil filter housing to the engine block. There are typically 5-6 bolts.
Gently pry up the old housing. It might be a bit stubborn due to the old gaskets.
Once removed, thoroughly clean the mating surface on the engine block. Remove all old gasket material to ensure a perfect seal for the new housing. A plastic scraper works well here.

Installing the New Housing

This is where precise work pays off, ensuring you benefit from your 2013 jeep wrangler oil filter housing replacement.

Carefully place the new oil filter housing onto the engine block, ensuring all new gaskets are properly seated.
Install the housing bolts. Hand-tighten them first to ensure they are all started correctly.
Using your torque wrench, tighten the bolts in a crisscross pattern to the manufacturer’s specified torque. This is usually around 105 in-lbs (12 Nm) for the housing bolts. Do not overtighten, as this can crack the new plastic housing!
Reconnect the coolant hoses to the new housing. Secure them with their clamps.
Reconnect all electrical connectors to the housing.

Refilling Fluids and Final Checks

Before putting everything back, double-check your connections.

Replace the intake manifold. Ensure the new intake manifold gaskets are properly seated.
