What is the installation method for the Cruze crankshaft rear oil seal?
2 Answers
First, rotate the crankshaft pulley to the position of the first cylinder. There is a small dot on the crankshaft pulley that should align with the longest protruding strip on the front oil seal housing, then install the rear crankshaft oil seal. After assembling the crankshaft into the cylinder block, the main bearing caps should be installed. Before assembling the rear main bearing cap, apply sealant to the rear part of the mating surface.
Hey, I've done the job of replacing the rear crankshaft oil seal on a Cruze a few times. It's quite a hassle, but the key is to follow the steps carefully. First, you need to securely lift the car and stabilize it with a jack and stands—no slacking off here, or it's unsafe. Then, remove the transmission assembly; it's pretty heavy, so you'll need help or a hoist to move it aside carefully. Once it's off, you'll see the old oil seal. Use a hook or pry bar to gently remove it, and check the shaft neck for any scratches. Clean the seat ring thoroughly—removing grease with a cleaner is crucial, or the new seal won't sit properly. Press the new seal in slowly with a professional tool or by hand, making sure it's even and not twisted. Apply some lubricant to help with sealing. When reinstalling the transmission, align it properly and tighten the bolts evenly. Finally, start the engine and let it run for a few minutes to check for leaks—if none, you're all set. I'd advise beginners not to rush into DIYing this job; it's easy to mess up and cause leaks, so it's better to leave it to a repair shop for peace of mind.
