Description
Geo Storm Timing Cover for Sale, Sporty 1990s Compact Coupe Engine Component
Geo Storm (1990-1993) was the sporty 2-door coupe/hatchback variant of GM’s Geo economy import brand. Unlike Metro/Prizm economy focus, Storm targeted performance-minded young buyers competing with Honda CRX, Toyota Paseo. Donor: Isuzu Impulse. Production at SIA (Subaru-Isuzu Automotive) Lafayette Indiana joint venture.
DISCONTINUED after 1993 – did NOT continue under Chevy brand (unlike Metro/Prizm/Tracker). Compact sporty coupe segment declined as buyers shifted to SUVs. Engines: 1.6L SOHC (95 HP base), 1.6L DOHC (130 HP GSi performance), some 1.8L variants.
Timing cover protects timing belt assembly from contamination. Cross-reference Isuzu Impulse (US sibling) and Isuzu Stylus (sedan variant). Often replaced during timing belt service. We inspect for damage, mounting, gasket surface.

Maximilien Goutard-Beaulieu –
Replaced timing cover on my 1992 Geo Storm GSi (the rare 1.6L DOHC 130 HP performance variant in hatchback body) during a complete timing belt service. The original cover had developed cracks from 30+ years of age and engine bay heat exposure. Vaz confirmed the GSi variant and 1.6L DOHC engine specifically. Sourced from a 1991 Isuzu Impulse RS donor (US sibling cross-reference, same DOHC engine). No damage, mounting holes intact, gasket surfaces perfect. Installed during full timing belt service
Yevgeniya Tikhonravova-Sokolskaya –
Bought timing cover for my 1993 Geo Storm 1.6L SOHC (base trim, last production year). Vaz emphasized the 1990-1993 production run and 1993-specific configuration. Sourced from a 1992 Isuzu Stylus donor (sedan variant cross-reference – same engine and timing cover). One star off because the SIA Lafayette Indiana production history (GM/Isuzu/Subaru joint venture) was new information to me – I didn’t realize this was produced in Indiana at a joint venture. The donor cross-reference saved significa
