2000 Jaguar
S-TypeSedan
Sedan
The 2000 Jaguar S-Type was a significant re-entry for Jaguar into the mid-size luxury sports sedan segment — a nameplate revival after a 35-year hiatus. Built on a platform shared with the Lincoln LS and developed under Ford's ownership, it blended classic Jaguar styling cues (the rounded fastback roofline, oval grille) with modern underpinnings. The 3.0L V6 was the entry-level powertrain, paired with a 5-speed automatic sourced from Ford/ZF. As a first-year model, the 2000 S-Type carries the reliability baggage typical of clean-sheet launches: electrical gremlins, early transmission issues, and cooling system quirks were documented widely in the first two model years. It's a car that rewards owners who stay on top of maintenance and budget for European luxury running costs — and punishes those who don't. Today, these are low-value, high-cost-to-own vehicles. Parts availability has thinned, independent shops familiar with Jaguar electronics are important to find, and deferred maintenance on a used example can quickly exceed the car's market value. Buy one for the driving experience with eyes wide open about the wallet.

Known for
- Classic Jaguar styling with a modern (for 2000) platform
- Smooth, refined 3.0L AJ-V6 engine when properly maintained
- Shared Ford/Lincoln LS architecture — some parts crossover
- Comfortable, driver-focused interior with wood and leather
- Strong braking and composed rear-wheel-drive handling
Best for
- Enthusiasts who want European luxury feel on a budget and can do their own research
- Owners with access to a trusted independent Jaguar/European specialist
- Drivers who prioritize style and driving character over long-term reliability
- Second or hobby car use rather than daily-driver dependence
Watch for
- Electrical system faults — window regulators, instrument cluster, and HVAC controls are failure-prone
- Cooling system neglect leading to overheating and head gasket damage
- Transmission issues (harsh shifts, slipping) on high-mileage examples
- Expensive dealer-only parts with limited aftermarket support
- Rust on undercarriage and suspension components, especially on Midwest/salt-road examples

Maintenance schedule
- 1 Every 5,000 miles or 6 months Engine oil and filter change — full synthetic, manufacturer-specified viscosity
The AJ-V6 VVT system is oil-cleanliness-dependent. Extended drain intervals or conventional oil accelerate sludge buildup and will trigger VVT codes (P0012, P0022 range). Use the correct viscosity — do not substitute.
- 2 Every 2 years or 30,000 miles Coolant system inspection and flush
Plastic cooling components age poorly. Inspect the overflow tank, hoses, and thermostat housing at each flush. OAT-compatible coolant only — mixing types accelerates corrosion.
- 3 Every 40,000–50,000 miles Transmission fluid and filter service
Often neglected on luxury cars. Fresh fluid restores shift quality and extends solenoid life. Use only the fluid type specified for this ZF-based 5-speed — incorrect fluid causes shift problems.
- 4 Every 60,000 miles Spark plugs (platinum or iridium)
Ignition misfires are harder on the catalytic converters and O2 sensors on this engine. Staying current on plugs prevents downstream expense.
- 5 Every 60,000 miles or at any sign of squealing Serpentine belt and tensioner inspection
Belt and tensioner failure leaves you stranded. Tensioners on aging Jaguars can seize without audible warning — replace the tensioner when replacing the belt.
- 6 Every 2 years Brake fluid flush
DOT 4 fluid absorbs moisture over time, lowering boiling point. Wisconsin salt seasons accelerate corrosion in brake calipers and lines. Fresh fluid protects the ABS module and caliper pistons.
- 7 Every spring (post-salt season) Undercarriage inspection for rust and suspension component condition
Road salt in Lake Geneva winters attacks brake lines, suspension bushings, and subframe hardware. Catching rust on brake lines before they fail is a safety imperative.
- 8 Every fall, before winter Battery load test
The S-Type's multiple electronic modules draw parasitic current and punish a weak battery. Sub-zero Wisconsin starts on a marginal battery will strand you. A battery over 4 years old should be load-tested, not just voltage-checked.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$1,200 – $3,500
Fuel
Premium fuel (91 octane minimum) required. At current upper Midwest prices and 15,000 mi/year at 19 MPG combined, expect roughly $2,000–$2,400/year in fuel.
Insurance
Moderate — mid-size luxury sedan with low market value keeps comprehensive premiums reasonable, but liability and medical coverage needs are normal. Expect $900–$1,500/year for a typical adult driver in Wisconsin.
This is a low purchase-price car with European luxury running costs. Routine maintenance alone (oil, brakes, fluids) runs $1,200–$1,800/year at an independent shop. Any unplanned repair — cooling system, electrical module, transmission work — can easily add $500–$2,500 in a single visit. Budget conservatively: assume at least one significant unplanned repair per year on a vehicle of this age. Parts sourcing can delay repairs due to limited aftermarket supply.
Seasonal care
Lake Geneva, WI Winter
- Load-test the battery every October — multiple aging modules and cold cranking demands will kill a weak battery fast in Lake Geneva winters.
- Switch to full synthetic oil rated for cold-weather starts (e.g. 5W-30) to ensure proper VVT system lubrication at sub-zero temperatures.
- Inspect and replace wiper blades with winter-rated blades; top off washer fluid with -20°F or lower rated fluid — standard fluid freezes on the windshield at highway speed.
- Inspect brake lines and fuel lines for rust perforation before winter — salt exposure on an aging Jaguar undercarriage is serious. Fix any soft spots before they become failures.
- Check tire tread depth and consider dedicated winter tires; the S-Type is RWD — it will spin and understeer on snow with all-seasons in poor condition.
- After each salted-road drive when possible, rinse the undercarriage to slow accelerating rust on suspension hardware and brake components.
Summer
- Monitor coolant temperature carefully during hot weather — the aging plastic cooling components are most likely to fail under heat stress. Watch the gauge.
- Check tire pressure monthly; heat causes pressure to rise roughly 1 PSI per 10°F increase. Over-inflation from summer heat wears center tread and reduces wet-road grip.
- Inspect the A/C system for refrigerant charge and compressor clutch operation before peak heat — recharging a 25-year-old system often reveals slow leaks at aged O-rings.
- Park in shade when possible; the S-Type's leather interior and wood trim fade and crack with prolonged UV exposure.
