How to replace front Crankshaft Seal on 4.3L V6 engine on Chevrolet Silverado?

Remove the crankshaft pulley and vibration damper. Note how the seal is installed-the new one must be installed to the same depth and facing the same way. Carefully pry the Crankshaft Seal out of the cover with a seal puller or a large screwdriver. If the Crankshaft Seal is being replaced with the timing chain cover removed, support the cover on top of two blocks of wood and drive the Crankshaft Seal out from the backside with a hammer and punch. Clean the seal bore to remove any old seal material and corrosion. Position the new Crankshaft Seal in the bore with the seal lip (usually the side with the spring) facing IN(toward the engine). A small amount of oil applied to the outer edge of the new Crankshaft Seal will make installation easier. Drive the Crankshaft Seal into the bore with a seal driver or a large socket and hammer until it's completely seated. Select a socket that's the same outside diameter as the Crankshaft Seal and make sure the new Crankshaft Seal is pressed into place until it bottoms against the cover flange. Check the surface of the damper that the Crankshaft Seal rides on. If the surface has been grooved from long-time contact with the seal, a press-on sleeve may be available to renew the sealing surface. This sleeve is pressed into place with a hammer and a block of wood. Lubricate the seal lips with engine oil and reinstall the vibration damper. Use a vibration damper installation tool to press the damper onto the crankshaft. Install the vibration damper-to-crankshaft bolt and tighten it to the torque specifications. Install the crankshaft pulley and tighten the bolts to the torque specifications. The remainder of installation is the reverse of removal.

Chevrolet Silverado Crankshaft Seal

Chevrolet Silverado Crankshaft Seal plays a quiet but critical role by sealing the front end of the crankshaft so engine oil stays inside the crankcase and every moving surface stays slick and cool. Constructed from a tough combination of metal for strength and rubber for flexibility, this Crankshaft Seal creates a tight round barrier that prevents leaks, reduces friction, and wear as mileage increases. When the seal becomes brittle or nicked, wet areas under the truck or dropping oil levels are the warning signs that the part can no longer hold the lubricant in place. Quick attention can stave off bigger engine trouble. Over the years, the basic Crankshaft Seal design has remained consistent across Chevrolet trucks, preferring this tried-and-true metal and rubber ring over radically different designs as the simple design is already well suited to the needs of Silverado engines. As a result, all modern Silverado still depend on a single main Crankshaft Seal located in the front of the engine, and the failure symptoms are also the same, so the diagnosis is familiar to owners who monitor the oil health. Regular inspections and timely replacement of the Crankshaft Seal keep Chevrolet powerplants running smoothly.

Each OEM Chevrolet Silverado 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.

Q: How to replace front Crankshaft Seal on 4.3L V6 engine on Chevrolet Silverado?
A:
Remove the crankshaft pulley and vibration damper. Note how the seal is installed-the new one must be installed to the same depth and facing the same way. Carefully pry the Crankshaft Seal out of the cover with a seal puller or a large screwdriver. If the Crankshaft Seal is being replaced with the timing chain cover removed, support the cover on top of two blocks of wood and drive the Crankshaft Seal out from the backside with a hammer and punch. Clean the seal bore to remove any old seal material and corrosion. Position the new Crankshaft Seal in the bore with the seal lip (usually the side with the spring) facing IN(toward the engine). A small amount of oil applied to the outer edge of the new Crankshaft Seal will make installation easier. Drive the Crankshaft Seal into the bore with a seal driver or a large socket and hammer until it's completely seated. Select a socket that's the same outside diameter as the Crankshaft Seal and make sure the new Crankshaft Seal is pressed into place until it bottoms against the cover flange. Check the surface of the damper that the Crankshaft Seal rides on. If the surface has been grooved from long-time contact with the seal, a press-on sleeve may be available to renew the sealing surface. This sleeve is pressed into place with a hammer and a block of wood. Lubricate the seal lips with engine oil and reinstall the vibration damper. Use a vibration damper installation tool to press the damper onto the crankshaft. Install the vibration damper-to-crankshaft bolt and tighten it to the torque specifications. Install the crankshaft pulley and tighten the bolts to the torque specifications. The remainder of installation is the reverse of removal.
