How do you remove and install front oil seal in V8 engine on Chevrolet Trailblazer?

Remove the crankshaft balancer and note the installation depth and orientation of the seal, ensuring the new one is installed the same way. Carefully pry the old oil seal out of the timing chain cover using a seal puller or a large screwdriver, taking care not to damage the crankshaft or distort the cover; wrapping electrician's tape around the screwdriver tip can help prevent damage. If replacing the seal with the timing chain cover removed, support the cover on two blocks of wood and drive the seal out from the backside using a hammer and punch, being cautious not to scratch or distort the sealing area to avoid leaks. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal and install it in the cover with the lip facing inward, using a large socket and hammer to drive it into place, ensuring it enters squarely and is at the proper depth. Check the balancer hub surface for grooves caused by long-term contact with the seal; if present, a press-on sleeve may be available to renew the sealing surface, which can be pressed into place with a hammer and block of wood. Lubricate the balancer hub with clean engine oil and reinstall the crankshaft balancer, completing the installation in reverse order of removal.

Chevrolet Trailblazer Crankshaft Seal

The Crankshaft Seal in Chevrolet Trailblazer vehicles is a unique product mounted at the front of the block of the motor vehicle. Normally comprising of metal and rubber, this round seal is helpful in avoiding leakage of the engine oil from the crankcase to enable appropriate lubrication of other important parts of the engine. There may come a time that a Chevrolet Trailblazer will develop some signs that suggest that Crankshaft Seal needs replacement due to being worn out or damaged, most especially when it already has a high mileage or developing oil leaks. To increase the durability of the engine and to prevent the Crankshaft Seal from getting worse, long time use and replacement are necessary. It should be noted that there might be some discrepancies in Crankshaft Seal depending on the model of the Chevrolet Trailblazer, yet the general functioning of the part does not seem to differ.

Each OEM Chevrolet Trailblazer Crankshaft Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
