How to install a one piece rear crankshaft seal in four cylinder engine on Pontiac G6?

The one piece rear Crankshaft Seal is pressed into the engine block and the crankcase reinforcement section. Begin by removing the transaxle and the driveplate. Pry out the old seal using a seal removal tool or a flat blade screwdriver. To prevent an oil leak after the new seal is installed, be very careful not to scratch or otherwise damage the crankshaft sealing surface or the bore in the engine block. Clean the crankshaft and seal bore in the block thoroughly and degrease these areas by wiping them with a rag soaked in lacquer thinner or acetone. Lubricate the lip of the new seal and the outer diameter of the crankshaft with engine oil. Position the new seal onto the crankshaft, ensuring not to roll over the lip of the seal. If marked, the words THIS SIDE OUT on the seal must face out, toward the rear of the engine. Use a special rear Crankshaft Seal installation tool (GM J42067 or an equivalent) to drive the seal into place. The remainder of installation follows the reverse order of removal.

How to remove and replace the front crankshaft seal in 2.5L four cylinder engine on Pontiac Grand Prix?

Remove the crankshaft pulley. Try to pry the old oil seal out with a seal removal tool or a screwdriver; be very careful as you don't want to scratch the crankshaft; this applies where the use of vinyl tape is useful to insulate the chucked screwdriver blade end. When installing the new seal spread ATV-type sealant on only the outer circumference of the seal and coat the seal lip with moly based grease or fresh engine oil. Centre the seal properly in its place in the bore then use a special tool to install it. If the special tool is not available, then the seal can be gently knocked into place using a large socket or piece of pipe and a hammer; the outer diameter of the socket or pipe should match the outer diameter of the seal and the seal should also be fully seated in the bore. The crankshaft pulley should then be fitted back then the rest of the parts replaced in a reverse manner to which they were removed. After starting the engine check for the oil leakage at the seal area.

Pontiac Crankshaft Seal secures the engine oil in its place and prevents untimely wear. Pontiac has a reputation of creating cars that were fast-handling, outspoken, and durable on the road, which were appreciated by all drivers. Starting with the old Pontiac Wide Track sedans and moving on to fire-breathing coupes, the brand pursued actual performance instead of showroom lipstick, overloading cars with huge engines, solid suspension, and cockpits that would beg you to downshift the gearbox and go. Pontiac styling led to exaggerated stances, driver-oriented dashboards and no-nonsense powertrains that shrugged through everyday abuse, but pulled heads at night cruises. Such an attitude of easy excitement continues to reverberate in each passing of the arrowhead badge through traffic. The Crankshaft Seal is mounted at the crank nose and creates a tight seal between the rotating metal and the outside world holding the lubricant and keeping out grit, heat, and pressure that would otherwise tear bearings and timing gear over time. New Crankshaft Seal aids in avoiding the under-car puddles, part belts safety, and maintaining the same level of oil consumption during commuting in the city or during long interstate hauls. Rebuilds will remain far off when a good Crankshaft Seal has to deal with the daily spin and fluctuation of temperature without hardening or cracking.

The crankshaft pulley should then be fitted back then the rest of the parts replaced in a reverse manner to which they were removed. After starting the engine check for the oil leakage at the seal area.
