Rubber or combined materials?
Traditionally, rubber has always been the material of choice when it comes to crankshaft seals. However, today's modern technology has paved the way for some innovations in making car parts and accessories. Though typical rubber seals remain reliable, those that are created using combined materials promise extra features such as lower-friction operation, excellent vacuum retention, and improved performance. Choose the type of material that best suits your budget, preference, and needs.
Final Tip: To ensure you get your money's worth, don't settle for anything less and buy from a brand that you can rely on. Today, you'll find crankshaft seals from brands like Corteco, Felpro, and Omix, which are backed by a reputation that you can trust.

Difficulty Level: Moderate
What you need to prepare:
- Jack and jack stands
- Metric socket set
- Metric wrench set
- Self-tapping screw
- New crankshaft seal
- Brake cleaner
- Motor oil
- RTV silicone
- Air impact gun (optional)
Step 1: Raise and support your car using the jack and jack stands. Raise it until you have enough space to work underneath your vehicle. Remove the front tire on the passenger side.
Step 2: Put a rag on top of your jack and place it beneath the oil pan. Raise your assembly some more by jacking it up until the engine moves.
Step 3: Using your sockets and wrenches, remove the following components: alternator belt, timing belt cover, timing belt, splash shield, crank pulley, and water pump pulley.
Step 4: To remove the crank bolts that are holding your crankshaft, lower your vehicle a little bit to gain access to your engine. If you have an air impact gun, this will allow you to remove the bolts without any difficulty; however, you can also do this task manually by using sockets and wrenches. Once you have already removed the bolts, remove the lower sprocket and check the slot of the keyway.
Step 5: Using the self-tapping screw, slowly remove the crankshaft seal. Wait for the seal to pop out before you use pliers to take it out.
Step 6: Before you attach your new seal, get a rag put some brake cleaner on it. Use this to clean the crankshaft and seal housing. After which, get the motor oil and wipe some on the inner part of your new seal. When you're done with the motor oil, get the RTV silicone and put some on the outer circumference of the seal.
Step 7: Attach the new seal to your crankshaft with utmost care by letting it glide. Once it is positioned, use a socket and tap it to make it even. Clean the outer parts of the seal using a rag and remove the excess silicone.
Tip: When reattaching and reassembling the components that you removed earlier, make sure you use the proper torque specs for security.
