GMC Sonoma Crankshaft Seal

The Crankshaft Seal on GMC Sonoma is an important part of the car fitted at the frontal side of the engine with the primary function of avoiding leakage of the engine oil in the crank case. This round seal is usual of metal rubber and is used to ensure that lubrication is provided on certain vital parts of the engine to reduce the amount of friction hence increasing the life of the engine. A crankshaft seal, like all the other seals can get damaged or wear out and this will lead to matters such as oil leakage and poor engine performance. Crankshaft seal failure symptoms can suggest a change in a vehicle that has traveled many miles. Even though there may be differences in the style of this housing depending on model year, differences in the material or the mode of construction, its role of sealing and protecting the engine remains the same.

Each OEM GMC Sonoma 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.

GMC Sonoma Crankshaft Seal Parts Questions & Experts Answers

  • Q: How to replace the front crankshaft seal on 4.3L V6 engine on GMC Sonoma?
    A: Disconnect the negative battery cable from the battery. Remove the upper and lower fan shrouds, the cooling fan, and the drive belt. Remove the bolts and separate the crankshaft drive belt pulley from the vibration damper. Remove the lower flywheel cover and have an assistant wedge a large screwdriver in the flywheel ring gear teeth to hold the engine from turning while you remove the bolt from the front of the crankshaft with a socket and breaker bar. Then use a puller to detach the vibration damper. Carefully pry the seal out of the cover with a seal removal tool or a large screwdriver. Clean the bore to remove any old seal material and corrosion. Position the new seal in the bore with the open end of the seal facing IN. Apply a light film of grease to the lip of the seal. Drive the seal into the bore with GM tool no. J-23042A, or equivalent, until it's completely seated. Reinstall the vibration damper, aligning its groove with the keyway in the crankshaft. Use a punch or screwdriver and hammer to drive the Crankshaft Seal out of the cover from the back side. Support the cover as close to the seal bore as possible. Clean the bore to remove any old seal material and corrosion. Support the cover on blocks of wood and position the new seal in the bore with the open end of the seal facing IN. Drive the Crankshaft Seal into the bore with a large socket and hammer until it's completely seated. Reinstall the cover. The remainder of the installation is the reverse of the disassembly. Start the engine and check for leaks.
