How do you remove and install a front crankshaft pulley and Crankshaft Seal in 2.4L four cylinder engine on GMC Terrain?

To remove the crankshaft pulley, first disconnect the cable from the negative battery terminal and remove the drivebelt. Raise the vehicle and support it securely on jackstands, then take off the splash shield from below the engine compartment by removing its mounting fasteners. Use a breaker bar and socket to remove the crankshaft pulley center bolt, employing a large pin spanner to prevent the pulley from rotating while loosening the bolt; discard the old bolt and obtain a new one for installation. It may be necessary to lock the pulley in position using a strap wrench or a large pin spanner, and wrapping an old drivebelt around the pulley can provide a better grip if using a strap wrench. Slide the puller off the nose of the crankshaft, and if the pulley is stuck, use a puller that bolts to the three threaded holes in the pulley hub, along with a spacer like a deep socket to avoid damaging the crankshaft. Next, use a seal puller to remove the crankshaft front oil seal, taking care not to damage the crankshaft or the seal bore; a screwdriver wrapped with tape can be used as an alternative. Clean the seal bore and check for nicks or gouges, and examine the hub area for signs of abnormal wear or scoring. For installation, coat the lip of the new seal with clean engine oil and drive it into the bore with a seal driver or a socket slightly smaller in diameter than the seal, ensuring the open side of the seal faces into the engine. Lubricate the sealing surface of the hub with clean engine oil, then install the crankshaft pulley/damper using a special installation tool, avoiding the use of a hammer. Install a new center bolt and tighten it to the specified torque, ensuring a new pulley bolt is used. The remainder of the installation follows the reverse order of removal, and finally, reconnect the battery.

GMC Terrain Crankshaft Seal

In this article, the Crankshaft Seal for GMC Terrain automobiles is examined as a functional part situated at the front section of the engine that provides a barrier to oil leakage of the crankcase. This round seal is normally made of a combination of metal and rubber and the main primary function is to uphold engine lubrication so that there can be minimal friction and therefore, less wearing of parts within an engine. A GMC Terrain Crankshaft Seal may degrade with time and especially when used in hard terrain thus requiring replacement by a professional. While the basic design remains consistent, variations may exist across different model years, but the primary function of the Crankshaft Seal remains unchanged: in order to prevent internal wear and to have the engine run thorough out its life without leakage of the required oil.

Each OEM GMC Terrain 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.
