Elring 590797 — Rear crankshaft seal Lanos, Nexia, Aveo, Lacetti, Nubira

The Elring 590797 rear crankshaft seal keeps oil inside the engine at the block-to-transmission joint and prevents it from leaking onto the clutch and into the flywheel area. The part is made of FPM (fluoro rubber), has an inner diameter of 80 mm, an outer diameter of 98 mm, a width of 10 mm, a left-hand helix direction, a dust lip and an A/BS profile; it is installed on the transmission side. This is a German seal with the number 590797, for which 164 analogs are available in the catalog.

The seal is used on Chevrolet Aveo (T200, T250/T255, T300), Lacetti, Lanos, Nexia and Nubira, as well as on a number of Acura CL, Buick Encore/Excelle HRV and Bedford Astra models. When selecting, it is important to verify not only the model and year but also the engine: the facts separately list the A15SMS engine on Buick Encore and the K20Z4 on Ariel Atom. Use the dimensions 80×98×10 mm, left-hand helix and transmission-side installation as your reference — they must match your part.

Among the replacements in the catalog are General Motors 06 14 821, Opel 90 325 571, Honda 91214pway01 and 91214PWJA01, Wilmink Group WG1223189, VAICO-VEMO V40-1800 — when choosing an analog, compare the A/BS profile, FPM material and presence of a dust lip. Compatibility is best checked by VIN or engine number, not just by model name. This seal is replaced when oil traces appear at the engine-to-transmission joint, when there is sweating in the flywheel area, or after the transmission is removed and the seal is already worn.
