1997 Chrysler LHS — 3.5L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1997 LHS 3.5L.

Body PASSENGER CAREngine 3.5LTransmission Automatic 4-spd

Built on the LH platform, this passenger car pairs a 3.5L engine with a 4-speed automatic transmission and specifies 5.5 quarts of 10W-30 API oil. While delivering EPA fuel economy ratings of 16/24/19 mpg, the 1997 model year recorded 96 total owner complaints primarily centered on the fuel system, gasoline area alongside two recalls. Within the broader 1993-2004 model run that saw complaint volumes peak at 412 in 1994 and drop to just 1 in 2003, this variant occupies a moderate position in the generation's reliability history, situated between the run's highest and lowest complaint totals.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 05281090AB. Note the factory engine air filter, fuel filter, serpentine belt and thermostat are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 30,000 mi; coolant every 7,500 mi. The big-interval services (every 7,500 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1997 Chrysler LHS sits late in the production arc shown in the federal record, and the data suggests it benefited from several years of refinement: complaints fell sharply from 1994's peak of 412 to 96 in 1997, while investigations dropped to 3 — the second-lowest figure in the dataset. This relative calm is somewhat deceptive, because the two model years immediately following (1998–1999) saw TSB volume surge to 141 and 147 respectively, indicating that service campaigns and engineering fixes were still being issued heavily even as consumer complaint noise eased. Within the 1997 record itself, the top complaint areas — fuel system (18), steering (11), and engine cooling plus hydraulic brakes (10 each) — concentrate on drivetrain and chassis systems, with 3 crash and 1 fire complaint adding modest but non-trivial safety exposure. Compared to the early-life chaos of 1994 and the post-1997 TSB and complaint rebound, 1997 is the calmest year in the early portion of the arc and a defensible used buy — provided a pre-purchase inspection specifically targets fuel delivery, steering play, cooling system integrity, and brake hydraulics, and confirms the 2 outstanding recalls have been completed.
