The 1998 Honda Passport: Engine, Transmission, and Core Specs

The 1998 Honda Passport is a mid-size SUV built on the Isuzu Rodeo platform, powered by a 3.2-liter V6 engine that produces 205 horsepower and 214 pound-feet of torque. This engine is paired with either a 4-speed automatic transmission or a 5-speed manual transmission, depending on the model year and trim level. The Passport came standard with rear-wheel drive, though four-wheel drive was available as an option on most trims.

The vehicle sits on a body-on-frame construction, which means the steel frame and body are separate components bolted together. This design gives the Passport better towing capacity than unibody SUVs of the same era, but it also means more road noise and a rougher ride on highways compared to car-based alternatives. The 1998 model year marked the second generation of the Passport, which ran from 1994 to 2002.

Key Takeaways

  • The 1998 Passport uses a 3.2-liter V6 engine with 205 horsepower and can tow up to 5,000 pounds when properly equipped, making it suitable for small trailers and boats.
  • Four-wheel drive models require regular maintenance of the transfer case fluid and front differential to prevent costly repairs, especially if you use four-wheel drive frequently.
  • The body-on-frame design means rust and frame corrosion are serious concerns on used examples, particularly in states with road salt, and should be inspected before purchase.
  • Fuel economy ranges from 16 to 19 miles per gallon depending on transmission type and drivetrain, which is typical for SUVs of this size and age but worth budgeting for.
  • Common wear items like the timing belt, water pump, and transmission fluid need attention at specific mileage intervals to prevent engine damage or transmission failure.

Fuel Economy and Real-World Consumption

The 1998 Passport achieves between 16 and 19 miles per gallon in mixed driving, with automatic transmission models typically returning slightly lower mileage than manual versions. Highway driving yields better fuel economy than city driving, but the V6 engine and body-on-frame weight mean this SUV will never be fuel-efficient by modern standards. If you are considering a used 1998 Passport, budget for regular fill-ups and factor fuel costs into your ownership expenses.

Four-wheel drive models consume slightly more fuel than rear-wheel drive versions because the transfer case and additional drivetrain components add weight and mechanical resistance. Tire pressure, wheel alignment, and engine condition all affect real-world consumption, so a well-maintained example will perform better than a neglected one. If the vehicle has been sitting unused or has high mileage, expect consumption to be at the lower end of that range.

Four-Wheel Drive System and Maintenance

The 1998 Passport four-wheel drive system uses a part-time transfer case, which means you manually engage four-wheel drive when you need it rather than having it operate automatically. This design is simpler and more durable than full-time all-wheel drive systems, but it requires the driver to understand when to engage it. Engaging four-wheel drive on dry pavement can damage the transfer case and drivetrain, so it should only be used on loose surfaces like gravel, snow, or mud.

The transfer case fluid should be changed every 30,000 to 50,000 miles if you use four-wheel drive regularly, and the front and rear differentials require their own fluid changes at similar intervals. Neglecting these services leads to internal wear, grinding noises, and eventual failure—repairs that can cost $1,500 to $3,000 depending on which component fails. If you are buying a used Passport with four-wheel drive, ask the seller for maintenance records showing these services have been performed.

Timing Belt, Water Pump, and Engine Maintenance

The 3.2-liter V6 engine in the 1998 Passport uses a timing belt rather than a timing chain, which means it will eventually wear out and require replacement. Honda recommends timing belt replacement at 105,000 miles or every 8 years, whichever comes first. If the belt breaks while the engine is running, the pistons can strike the valves and cause catastrophic engine damage—a repair that costs $3,000 to $5,000 or more. This is not a maintenance item you can skip or delay.

The water pump is driven by the timing belt, so it makes sense to replace it at the same time you replace the belt, even if it is not yet failing. The combined cost of timing belt and water pump replacement typically runs $1,200 to $1,800 at an independent shop. If you are looking at a used 1998 Passport with over 105,000 miles, confirm that the timing belt has been replaced and ask for the receipt. If it has not been replaced, budget for this repair when ready after purchase.

Transmission Fluid and Automatic Transmission Care

The 4-speed automatic transmission in the 1998 Passport benefits from regular fluid and filter changes, which should be performed every 30,000 to 60,000 miles depending on driving conditions. Transmission fluid breaks down over time and loses its ability to lubricate and cool the internal components. Neglecting fluid changes leads to sluggish shifting, delayed engagement, and eventually internal wear that requires a full transmission rebuild or replacement—a $2,500 to $4,000 repair.

If you are buying a used Passport with an automatic transmission, check the fluid color and smell. Healthy transmission fluid is bright red and has a slightly sweet smell. Dark red or brown fluid with a burnt smell indicates the transmission has been running hot and may have internal damage. A transmission that shifts hard, hesitates, or slips between gears should be inspected by a mechanic before you purchase the vehicle.

Rust, Frame Corrosion, and Structural Inspection

The body-on-frame construction of the 1998 Passport makes it vulnerable to rust and frame corrosion, especially in climates where road salt is used during winter. The frame sits low and collects moisture, dirt, and salt spray, which accelerate corrosion over time. A rusted frame loses structural integrity and can affect handling, braking, and crash safety. If you are inspecting a used Passport, get underneath and look for orange or brown discoloration, flaking paint, or soft spots in the frame metal.

Frame corrosion is not something you can repair affordably—once the metal has corroded significantly, the vehicle is unsafe and uneconomical to fix. If you are considering a Passport from a rust-belt state or one that has been exposed to road salt, have a mechanic inspect the frame with a lift. A vehicle with surface rust on the frame may still be safe, but deep pitting or holes in the metal are a reason to walk away from the purchase.

Suspension, Steering, and Brake System Wear

The 1998 Passport suspension uses coil springs in front and a leaf spring rear axle, a design that is durable but prone to wear on the ball joints, tie rods, and bushings. These components should be inspected every 50,000 miles and replaced when they show play or looseness. Worn suspension parts cause clunking noises, uneven tire wear, and poor handling. Replacing a ball joint or tie rod typically costs $150 to $400 per component at an independent shop.

The brake system uses disc brakes in front and drums in the rear. Brake pads wear out every 40,000 to 70,000 miles depending on driving habits, and brake fluid should be flushed every two years to prevent moisture buildup. The rear drum brakes are less common on modern vehicles, so finding a mechanic familiar with them is important. If the brake pedal feels soft, spongy, or sinks to the floor, the brake system needs when ready attention before you drive the vehicle.

Interior Features and Comfort Considerations

The 1998 Passport came with cloth or leather upholstery depending on trim level, and most models included air conditioning, power windows, and power locks as standard equipment. The interior is functional but basic by modern standards—there is no backup camera, no touchscreen, and no advanced safety features. The dashboard can develop cracks over time, especially in vehicles exposed to intense sun, but this is a cosmetic issue rather than a mechanical one.

Seating is comfortable for short trips, but the Passport is not designed for long-distance highway driving. The ride is bouncy on rough roads because of the body-on-frame construction and leaf spring rear suspension. If you plan to use the vehicle for weekend trips or light off-road driving, the interior comfort is adequate. If you need a daily driver for long commutes, a more modern SUV or crossover will be more comfortable and reliable.

Frequently Asked Questions

How much can a 1998 Honda Passport tow?

The Passport can tow up to 5,000 pounds when equipped with the proper hitch and brake controller. This is suitable for small utility trailers, jet skis, or lightweight boat trailers. Always check the owner's manual for the exact towing capacity of your specific model, as it varies slightly by trim level and drivetrain configuration.

What is the difference between the 1998 Passport and the Isuzu Rodeo?

The 1998 Passport and Isuzu Rodeo share the same platform and engine, but the Passport is badged and sold by Honda. The Passport has slightly different styling, interior trim, and features, but mechanically they are nearly identical. Parts are often interchangeable between the two vehicles, which can be helpful when sourcing replacements.

Is the 1998 Passport good for off-road driving?

The Passport is capable of light to moderate off-road driving thanks to its body-on-frame construction and available four-wheel drive. However, it is not designed for extreme terrain or rock crawling. Ground clearance is adequate for forest roads and gravel trails, but the suspension is not as robust as dedicated off-road vehicles like the Toyota 4Runner or Jeep Wrangler.

What should I look for when buying a used 1998 Passport?

Check the timing belt replacement history, inspect the frame for rust, test the four-wheel drive system if equipped, and verify that transmission fluid is bright red and not burnt-smelling. Have a mechanic inspect the suspension, brakes, and steering components for wear. Ask for maintenance records showing regular oil changes and fluid services.

How reliable is the 1998 Honda Passport engine?

The 3.2-liter V6 is a robust engine that can reach 200,000 miles or more with regular maintenance. The main concern is the timing belt, which must be replaced at 105,000 miles to prevent catastrophic engine damage. Beyond that, the engine is straightforward and parts are widely available, making repairs relatively affordable compared to more complex modern engines.
