1998 DODGE CARAVAN

Typical onset: 80,000-140,000 mi

Symptoms: Slipping between gears, especially 2nd to 3rd, Delayed engagement when shifting from Park to Drive, Burnt transmission fluid smell, dark or metallic fluid, Complete loss of forward gears, stuck in limp mode

Fix: The 41TE four-speed auto is infamous for solenoid pack failures, worn clutch packs, and torque converter issues. Rebuilt transmission with upgraded solenoid pack is typical fix, 6-9 hours labor. Many owners simply scrap the vehicle at this point due to low resale value.

Estimated cost: $1,800-3,200

Typical onset: 90,000-150,000 mi

Symptoms: White smoke from exhaust, especially on cold start, Coolant loss with no visible leaks, needs frequent top-off, Overheating or erratic temperature gauge readings, Oil contamination in coolant reservoir (milky appearance)

Fix: These engines blow head gaskets between cylinders or into coolant passages. Both heads typically need resurfacing, new gaskets, timing components while apart. 12-16 hours labor. Often not economical on a vehicle this old.

Estimated cost: $1,500-2,800

Typical onset: 100,000-180,000 mi

Symptoms: Heavy knocking from engine block, worse under load, Metal shavings or glitter in oil during changes, Sudden catastrophic failure with rod through block, Low oil pressure warning at idle

Fix: The Mitsubishi 3.0L has weak connecting rod bearings and piston ring issues. Once knocking starts, it's short block or used engine replacement territory. 18-24 hours for engine swap. Parts availability for this engine is declining.

Estimated cost: $2,500-4,500

Typical onset: 60,000-120,000 mi

Symptoms: Red transmission fluid puddles under vehicle, Fluid leaking near radiator or along frame rails, Low transmission fluid level, slipping when hot, Rust-through at steel line fittings or along length

Fix: Steel cooler lines rust through, especially in salt states. Must replace both lines as preventive measure, not just the leaking one. 2-3 hours labor if caught early before transmission damage occurs.

Estimated cost: $250-500

Symptoms: Window drops into door, won't stay up, Grinding or clicking noise when operating windows, Window operates very slowly or gets stuck halfway, Driver's side most common, then sliding door windows

Fix: Plastic window regulator gears strip out or cables fray. Need regulator assembly replacement, often available as improved aftermarket units. 1.5-2.5 hours per door depending on which one.

Estimated cost: $180-350

Typical onset: 70,000-130,000 mi

Symptoms: Rough idle, especially when cold, Check engine light with lean codes (P0171/P0174), Whistling or hissing sound from engine bay at idle, Poor fuel economy, hesitation on acceleration

Fix: Upper intake plenum gasket deteriorates, causing vacuum leaks. Must remove upper plenum to replace gasket and often lower intake gaskets while there. 3-4 hours labor. Common preventive maintenance item.

Estimated cost: $350-600

Typical onset: 80,000-140,000 mi

Symptoms: Clunking over bumps from front end, Steering wander, vehicle pulls to one side, Uneven tire wear on inside or outside edges, Visible play in front wheels when jacked up

Fix: These minivans are hard on front suspension due to weight. Lower ball joints and strut mounts wear together. Replace struts with loaded assemblies (includes mounts) and lower ball joints. 4-5 hours for complete front end refresh.

Estimated cost: $700-1,200
