Running a 2000 Mitsubishi Eclipse: What Actually Works
The 2000 Mitsubishi Eclipse A Precise Blend Of Performance And Practicality Defining A New Millenniums Sports Coupe is a lot more than the spec sheet suggests, but only if you know where the factory cuts corners. I spent nearly a decade working on these at a shop before buying my own GS-T. The short version: they're decent cars when treated like what they are. They're not Porsches. They're not Supras. They're affordable front-wheel-drive or all-wheel-drive coupes with a 2.0L turbo four, a five-speed manual option, and a reputation for being underappreciated. The convertible version of the 2000 Eclipse, sometimes called the Spyder, has a particular set of problems that most owners miss until they're staring at a broken top mechanism. I picked up a '00 GS-T Spyder in 2018 with 87,000 miles. The previous owner had replaced the soft top but never addressed the hydraulic lines. Within three weeks, the driver's side window wouldn't roll up automatically because the sunroof harness was damaged from a factory routing error. That harness runs through the same channel as the top's hydraulic pump wiring. It's a known design flaw. The fix is rerouting the harness to a separate conduit and adding a loom. Costs about forty dollars in materials and two hours of your time if you have basic hand tools. The 2G Eclipse shared its platform with the Eagle Talon and Plymouth Laser. Parts interchange across all three, which matters because Mitsubishi stopped making new Eclipse bodies after 2005. If you're looking at a 2000 model, check the VIN to confirm whether it's the 2.0L 4G63T turbo (GS-T) or the 2.5L V6 SOHC turbo (GS). The 4G63T is the one you want for performance work. The 6G72 V6 in the GS is torquier off idle but less responsive with forced induction. Neither engine is bulletproof, but the 4G63 has a deeper aftermarket ecosystem.
Maintenance That Keeps This Thing Alive
Most people who buy a 2000 Eclipse know it's a turbo car and immediately start thinking about bolt-ons. That's backwards. These engines are easy to wreck if the basics aren't handled first. The cooling system is the weak point. The water pump sits behind the timing belt, which means every timing belt service also requires a water pump replacement unless you're willing to split that labor cost later. I've seen too many owners skip it to save a hundred and twenty dollars, then watch a seized water pump destroy the new belt within six months. Check the CV axles on any AWD model. The inner joints wear out faster than you'd expect, especially if the car saw winter driving with old fluid. You'll feel a clunk when taking off from a stop in first gear, and sometimes vibration at highway speeds. Replacement axles run about two hundred fifty dollars each for decent aftermarket units, and the job is straightforward if you have a jack and some socket sets. Doing it yourself saves roughly two hundred dollars in labor at a shop. Transmission fluid changes on the five-speed manual are not optional. The stock shifter feels vague when the fluid breaks down, and second gear gets particularly crunchy around eighty thousand miles. Use a quality 75W-90 GL-4 gear oil, not GL-5. The GL-5 additives corrode the brass synchronizer rings inside the transmission. I learned that the hard way with a friend's car that needed a full rebuild after someone used the wrong fluid for three years.
Common Failures and What to Expect
The oxygen sensor on the 4G63T exhaust manifold cracks over time. You'll get a P0135 code and a check engine light, and the car will run slightly rich. The fix is replacing the upstream O2 sensor, but here's the thing most guides don't mention: the sensor is tight against the manifold heat shield. You need an oxygen sensor socket and about twenty minutes of patience. Using a regular wrench and cutting corners just strips the sensor threads in the manifold, which turns a thirty-dollar repair into a two-hundred-dollar one. Ignition coils on these engines fail intermittently. The problem shows up as a misfire under load, usually at highway speeds or during hard acceleration. A cheap OBD2 scanner will tell you which cylinder is misfiring, but the real test is pulling the coil pack and checking for carbon tracking on the insulators. I've replaced coils on a car only to have the same misfire return because the spark plug tubes had accumulated oil from a worn valve cover gasket. That gasket leak is common on higher-mileage examples. The fix involves removing the intake manifold on the 4G63T, which is a four-hour job if you're methodical about it. The GS automatic transmission does not handle much more than twenty-five pound-feet of additional torque beyond stock without modifications. If you're planning any serious boost work on an automatic GS, you need a reinforced transmission or you're just delaying the inevitable failure. The manual gearbox handles more, but the clutch on the turbo models is undersized for anything past mid-thousand-rpm peak horsepower. People who push these cars past three hundred wheel horsepower on the stock clutch usually find themselves buying a new one within five thousand miles.

Practicality in this car is relative. The back seats are tight. The trunk is decent for a coupe. Fuel economy with the turbo manual averages around twenty miles per gallon in mixed driving if you're gentle, and twelve if you aren't. Insurance is cheap compared to a WRX or Integra. That's part of why these cars are worth considering now, before the market catches up to what they actually are. They're not the fastest cars from the year 2000, and they're not the most refined. But for the money, they deliver more genuine performance per dollar than almost anything else in their price range. If you're looking at buying one, prioritize condition over mileage. A well-maintained 120,000-mile Eclipse is a better car than a neglected 60,000-mile example. Check the records. Look for consistent oil changes with full synthetic. Smell the cabin for coolant leaks, which indicate head gasket work that may have been done poorly. Test drive it cold. Listen for any ticking from the valve train, which points to oil starvation issues from extended drain intervals. The 4G63T is robust, but it needs clean oil at all times. Parts availability is good. RockAuto carries everything, and junkyard options are plentiful since these were sold in significant numbers. The main constraint is that Mitsubishi no longer produces any Eclipse parts, so you're dependent on the aftermarket and salvage yards. For common wear items like control arm bushings, sway bar links, and brake components, that's not a problem. For body panels or trim pieces, you might wait a few days for shipping or hunt through pull-it-yourself yards.
The ABS module on AWD models is another failure point. These cars use the same ABS unit as the Galant of the same era, and the internal solenoids can stick. You'll get an ABS warning light and occasionally the traction control engages without braking. Replacement modules run three to five hundred dollars for remanufactured units. Some people disable the system entirely, but that's not recommended if you plan to drive in wet conditions. The anti-lock function actually works well on these, and losing it makes a heavy car even harder to manage on slippery surfaces. One thing people overlook is the importance of the rear diff fluid on AWD models. The rear differential uses a viscous coupling that degrades over time, and failing to replace the gear fluid leads to rough engagement between front and rear axles. You'll notice a slight shudder during hard acceleration in second and third gear. New fluid every sixty thousand miles costs about twenty dollars in gear oil and ten minutes of your time. Skipping it will eventually cause the viscous coupling to fail, which is a much more expensive repair. The interior plastics on these cars crack from UV exposure, especially the dash and the steering column covers. It doesn't affect operation, but it makes a nice example look worn faster than it should. A simple dressings application every few months slows the process significantly. If you find a pristine one, it's worth paying a premium, because interior restoration for the 2G Eclipse is difficult. Replacement dash pads exist from some aftermarket suppliers, but fitment can be finicky.
Overall, the 2000 Eclipse is a car that rewards knowledge and punishes neglect. The people who buy them without researching the common failure points tend to have bad experiences and tell others to avoid them. The people who learn the quirks, do the maintenance proactively, and treat them as what they are—a competent, affordable sports coupe from the turn of the millennium—end up with one of the best value propositions in the used car market. They just don't get the attention they deserve because they don't have the badge prestige of a Honda or Toyota.
