Step-by-Step Guide to Removing Valve Springs from Subaru Outback
Now that you have all the necessary tools and materials, you’re ready to begin the valve spring removal process. Follow these steps carefully to avoid damaging any engine components.
Step 1: Prepare Your Work Area
Before you start working, make sure you have enough space to work safely and comfortably. Park your Subaru Outback on a level surface and apply the parking brake. Open the hood and remove the spark plug wires and spark plugs. This will make it easier to access the valve springs.
Step 2: Remove the Cylinder Heads
To access the valve springs, you’ll need to remove the cylinder heads. Start by removing the bolts that secure the cylinder head cover to the cylinder head. Then remove the camshaft sprocket bolts and the timing belt. Remove the rocker arm cover and rocker arm assembly.
Step 3: Compress the Valve Springs
Use the valve spring compressor to compress the valve springs. This will allow you to remove the keepers, retainers, and valve springs. Place the compressor over the valve spring and compress the spring by tightening the compressor. Make sure the keepers and retainers are seated properly.
Step 4: Remove the Valve Springs
With the valve spring compressed, remove the keepers and retainers. Slowly release the compressor to remove the valve spring. Keep the valve spring and all of its components together so that you can re-install them later.
Step 5: Inspect and Clean the Valve Components
Inspect the valve spring, keepers, and retainers to make sure they’re in good condition. If any components are damaged or worn, replace them with new components. Clean the valve components with a parts cleaner to remove any dirt or debris.
Step 6: Replace the Valve Springs (Optional)
If you’re replacing the valve springs, now is the time to install the new springs. Place the new spring on the valve stem and use the compressor to compress the spring. Install the keepers and retainers.
Step 7: Reinstall the Cylinder Heads
Once you’ve replaced the valve springs (if necessary) and cleaned all of the valve components, you can re-install the cylinder heads. Use a torque wrench to tighten the cylinder head bolts to the manufacturer’s specifications. Reinstall the rocker arm assembly, camshaft sprocket, and timing belt. Replace the spark plugs and spark plug wires.
