Changing Oil Pan Of Honda Crv: A Step-By-Step Guide

The Honda CR-V is a popular vehicle, but even the most reliable cars sometimes need repairs. One issue that some owners of the 2010 Honda CR-V have faced is a problem with the oil pan. The oil pan is the reservoir for engine oil, and it is bolted to the engine block. While oil pans do not typically need to be replaced, external damage or an improperly tightened drain plug can cause leaks. This guide will cover the steps to replace the oil pan on a 2010 Honda CR-V, a process that can take around 4 hours for a technician to complete.

Remove the engine

To remove the engine of a 2010 Honda CRV, follow these steps:

Firstly, ensure you have the anti-theft code for the audio system and the navigation system (if equipped), and write down the XM radio presets. Next, secure the hood in the wide-open position, using the hood support rod. Now, relieve the fuel pressure, and disconnect the negative cable from the battery, followed by the positive cable. Remove the battery, and then the air cleaner housing assembly.

Now, remove the harness clamp and ground cable, and then remove the battery cables from the under-hood fuse/relay box. Disconnect the harness connector, and remove the harness clamp. Remove the powertrain control module (PCM) cover, and then remove the PCM itself by removing the three bolts securing it. Disconnect the PCM connectors and the engine wire harness connector. Remove the harness clamps, and then the PCM bracket.

Now, remove the evaporative emission (EVAP) canister hose and the brake booster vacuum hose. Remove the quick-connect fitting cover, and then disconnect the fuel feed hose. Remove the drive belt, and then the power steering (P/S) pump. Remove the P/S hose from the clamp.

At this point, you should raise the vehicle on a lift to full height. Remove the front wheels, and then the splash shield. Loosen the drain plug in the radiator, and drain the engine coolant. Drain the engine oil, and then the automatic transmission fluid (ATF).

Now, disconnect the air fuel ratio (A/F) sensor connector and the secondary heated oxygen sensor (secondary HO2S) connector. Remove the three-way catalytic converter (TWC). Remove the shift cable, and then separate the knuckles from the lower arms.

Remove the propeller shaft, and then the bolt securing the P/S fluid line bracket. Unclamp the P/S fluid line clamps on the front subframe. Remove the bolts securing the left and right steering gearbox mounting brackets.

Now, remove the bolt securing the automatic transmission fluid (ATF) filter, and then the lower torque rod. Make reference lines at both ends of the subframe that line up with the body. Remove the subframe mounting bolts on both sides. Attach the subframe adapter to the subframe, and hang the belt of the adapter over the front of the subframe, securing it with its stop.

Now, raise the jack and line up the slots in the arms with the bolt holes on the corner of the jack base, attaching them with bolts. Remove the subframe, and then the lower torque rod bracket. Remove the torque converter cover, and then the bolts securing the oil pan. Using a flat-blade screwdriver, carefully separate the oil pan from the block. Now, remove the oil pan.

Finally, remove the crankshaft and pistons, and check the piston for distortion or cracks.

Drop the subframe

To drop the subframe of a 2010 Honda CRV, follow these steps:

Firstly, make sure you have the necessary tools and safety equipment. This may include a jack, jack stands, axle stands, and other general tools. It is also important to wear protective gear, such as gloves and eye protection.

Next, you will need to raise the vehicle to full height using a jack. Ensure the vehicle is secure and will not roll or lower unexpectedly. Once the vehicle is raised, drain the engine oil.

After draining the oil, you will need to remove the front wheels. This will give you access to the subframe and its mounting bolts. Place the wheels aside in a safe location.

Now, you can begin to remove the components attached to the subframe. This includes the splash shield, the air-fuel ratio (A/F) sensor connector, and the secondary heated oxygen sensor (secondary HO2S) connector. You will also need to remove the three-way catalytic converter.

The next step is to remove the shift cable and separate the knuckles from the lower arms. This will involve some careful maneuvering, so take your time and ensure you are comfortable with the process before proceeding.

Once the knuckles are separated, you can remove the propeller shaft. This will provide you with better access to the subframe.

Now, you will need to remove the bolts securing the power steering (P/S) fluid line bracket. Be sure to also unclamp the P/S fluid lines on the front subframe.

The following components will also need to be removed:

• The bolts securing the left and right steering gearbox mounting brackets
• The bolt securing the automatic transmission fluid (ATF) filter
• The lower torque rod

At this point, you should make reference lines at both ends of the subframe that line up with the body. This will help you during the reinstallation process.

Now, you are ready to remove the subframe mounting bolts on both sides. With these bolts removed, carefully lower the subframe using the jack.

Once the subframe is lowered, you can detach any remaining components or brackets attached to it. Ensure you keep the removed parts organized and remember their correct locations for reassembly.

Remember to consult a qualified mechanic or a service manual for specific details and variations that may apply to your vehicle.

Clean mating surfaces

To clean the mating surfaces of your 2010 Honda CR-V's oil pan, you will first need to remove all the old liquid gasket from the oil pan mating surfaces, bolts, and bolt holes. You can use a wire brush or a straight-edge blade to remove any residue.

Once you have removed the residue, clean and dry the oil pan mating surfaces. You can use brake cleaner to clean the surface.

After cleaning, apply liquid gasket, P/N 08717-0004,08718-0001, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the oil pan and to the inner threads of the bolt holes. Install the component within 5 minutes of applying the liquid gasket.

If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes. If too much time passes after applying the liquid gasket, remove the old liquid gasket and residue, then reapply a new liquid gasket.

Check for leaks

After you've replaced the oil pan on your 2010 Honda CRV, it's important to check for leaks. Oil leaks can be caused by a worn-out gasket or impact damage. Symptoms of a leaking oil pan include a puddle of oil under your vehicle, a greasy oil pan and exhaust system after driving, low oil levels, and a burning smell coming from the engine compartment.

To check for leaks, first, make sure your vehicle is parked on a level surface and set the parking brake. Then, place a container under the engine to catch any potential leaks. Remove the drain plug and allow the oil to drain into the container. Once the oil has finished draining, reinstall the drain plug and remove the container.

Next, start the engine and carefully inspect for leaks. Common areas for leaks include the drain plug, the oil pan gasket, and the oil filter. If you notice any leaks, tighten the drain plug, oil filter, or any other fittings as needed.

If you still notice leaks after tightening the fittings, you may need to replace the gasket or the oil pan itself. This process typically involves removing any necessary components for access to the oil pan, unbolting the oil pan, removing the old gasket, cleaning the mounting surface, installing a new gasket, and reinstalling the oil pan.

It's important to consult a repair manual or a trusted mechanic if you're unsure about any part of the process.
