Chevrolet Avalanche Crankshaft Seal

The Crankshaft Seal is a part found in Chevrolet Avalanche models; It is situated at the front of the engine, and it is crucial. Usually consisting of metal and rubber, this bellowed seal is normally secured on a round base and it is responsible for minimizing oil leakages from the crankcase of the engine. The Crankshaft Seal also gives protection to vital and highly stressed parts of any engine as it minimizes friction and wear out and allows the proper and sufficient supply of lubricants. In case one or another signal telling about the high milage or oil leaks appears, it is recommended to have Crankshaft Seal changed to prevent the worsening of the vehicle conditions.

Each OEM Chevrolet Avalanche 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.

Chevrolet Avalanche Crankshaft Seal Parts Questions & Experts Answers

  • Q: How to remove and install front Crankshaft Seal in V8 engine on Chevrolet Avalanche?
    A: Remove the crankshaft balancer. Note how the seal is installed the new one must be installed to the same depth and facing the same way. Carefully pry the oil seal out of the cover with a seal puller or a large screwdriver. Be very careful not to distort the cover or scratch the crankshaft! Wrap the electrician's tape around the tip of the screwdriver to avoid damage to the crankshaft. If the seal is being replaced with the timing chain cover removed, support the cover on top of two blocks of wood and drive the seal out from the rear with a hammer and punch. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip (spring side) facing IN. Drive the seal into place with a large socket and a hammer (if a large socket isn't available, a piece of pipe will also work). Make sure the seal enters the bore squarely and stops when the front face is at the proper depth. Check the surface on the balancer hub that the crankshaft seal rides on. If the surface has been grooved from long-time contact with the seal, replace the crankshaft balancer. Lubricate the balancer hub with clean engine oil and reinstall the crankshaft balancer. The remainder of installation is the reverse of removal.
