Acting as your front engine cover, the timing cover is an extremely important component that protects your timing chains and timing gear from getting contaminated by dirt and debris. However, just like any other component in your vehicle, it will eventually get worn out after years of continued use. When left unchecked, it can cause leaks and other problems that will bring you nothing but hassles on the road. To bring back your ride's original performance, address the problem of your assembly right away.
Difficulty Level: Moderate
Things to prepare:
- Impact wrench
- Drain pan
- RTV silicone
- Harmonic balancer puller
- Pry bar or flathead screwdriver
- Replacement timing cover
- Replacement timing cover gasket
Step 1: Before you start, make sure you are parked on flat level ground. If you are going to move your car, wait for the engine to cool down for about 30 minutes before you proceed to the next step.
Step 2: Open your hood and use a wrench to remove your negative battery terminal.
Step 3: Place your drain pan underneath the radiator pan. To start draining coolant, unscrew your radiator's main bolt and allow the fluid to flow into your drain pan.
Step 4: Once you are done draining, get the impact wrench and loosen the nut at the center of your harmonic balancer. Doing this step will prevent your crankshaft from spinning while you are doing your repairs.
Step 5: After that, slide your harmonic balancer to take it out of your assembly using the harmonic balancer puller. Next, locate your water pump and remove its bolts.
Step 6: To take out the timing cover, start by removing the bolts underneath the oil pan. Once the bolts are out, use a pry bar or flathead screwdriver to detach the timing cover.
Step 7: Before attaching your new cover, clean the mounting point by scraping off the remnants of your old timing cover gasket with a gasket scraper.
Step 8: Install a new timing cover gasket that's painted with gasket sealant in your assembly. Before attaching your new cover, coat its mounting surface with RTV silicone sealant.
Step 9: Install your new timing cover by positioning it on your engine, making sure the dowel pins are aligned. To secure the connection, bolt in and torque its fasteners using a wrench. Tighten the bolts according to your vehicle's specs.
Step 10: Reinstall all the components that you removed earlier by reversing the order in which they were taken out.
Step 11: Close the main bolt and replenish your radiator's coolant. Don't forget to reconnect your negative battery cables before you start your engine and allow it to reach its proper operating temperatures. Keep on refilling your radiator with coolant as needed.
Removing and replacing your timing cover may take from one to two hours to be completed.
