    Q:
    How to replace the front Crankshaft Seal in 4.6L V8 engine on Cadillac DTS? Posted by Faye O.
    A:
    To install the timing cover, first remove the drivebelt and loosen the bolts on the right front wheel, then raise the vehicle and support it securely on jackstands before removing the right front wheel. Next, take off the splash shields from below the engine compartment and the right fenderwell, followed by the engine-to-transaxle brace and the torque converter cover, locking the flywheel to the transaxle with a special tool. If there isn't enough room to remove the damper, support the engine/transaxle subframe with a heavy-duty floor jack, loosen the rear subframe bolts, and lower the subframe until the crankshaft damper is clear of the fenderwell. Use a strap or chain wrench to hold the damper while removing the center bolt with a long breaker bar, ensuring the engine is securely locked from turning. Attach a puller to the damper to draw it off the crankshaft carefully, then remove the seal from the cover with a seal removal tool, applying penetrating oil to ease the process. Clean the bore, position the new seal with the open end facing inward, and drive it squarely into the bore until fully seated. Next, remove the power steering hose bracket bolt, the drivebelt tensioner bolt, and the drivebelt idler pulley bolt, then take off the crankshaft damper and the right engine mount and bracket. Remove the engine front cover and gasket, prying it loose carefully if stuck, and drive the seal out from the back side while supporting the cover. Clean the bore, position the new seal, and drive it into place. Remove old sealant from the front cover and engine block, ensuring the threaded bolt holes are clean. Apply RTV sealant to the mating surfaces and install the front cover, torquing the bolts in a specific order. Finally, apply anti-seize compound to the crankshaft snout and grease to the seal lips before installing the damper, using the retaining bolt to pull it onto the crankshaft.
