How to remove and install the rear crankshaft seal in six cylinder engine on Chevrolet Trailblazer?

First, you need to take out the driveplate and thereby observe the oil seal, oil pan, surface of the engine block and housing of the rear Crankshaft Seal since an oil pan gasket leak can give the similar sign as a rear Crankshaft Seal leak. Next, the rear Crankshaft Seal housing bolts should be withdrawn and two bolts need to be inserted into the jackscrew holes at the housing then each of the screw should be tightened until the housing is detached from the block, after which it should be removed. Remove the rear Crankshaft Seal from the housing and make sure that there are no nicks grooves or damaged part on the crank shaft. In installation, it is required to clean and check the oil seal housing next, lubricate outer seal face with engine oil slightly while the inner part of the face contacting the crank shaft should be free from oil in a slight sense in order avoid leakage. Fit the seal into the housing to face the lips of the rubber toward the engine; it should be driven in to the depth of the original seal, using a specific tool if available to ensure that it does not go deeper. Extinguish a 3/16-inch wide line of RTV sealant in a pattern to the mating surface of the housing and the engine block, thereafter installing the housing over the block while preventing the seal lips from folding around the rear of the crankshaft. Last, fasten and torque the bolts to the required amount of turn then reassemble the driveplate and transmission.

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.
