1992 DODGE CARAVAN

Typical onset: 80,000-140,000 mi

Symptoms: Harsh or delayed shifts between gears, especially 2nd to 3rd, Slipping under acceleration or won't move in any gear, Transmission fluid dark brown or burnt smell, Check engine light with transmission codes

Fix: The A604 4-speed auto is the Achilles heel. Internal clutch packs and solenoid pack fail. Rebuild takes 8-12 hours; many shops won't touch these anymore and recommend remanufactured unit swap. External oil cooler lines rust through and starve the trans—catch that early and you might avoid the big job.

Estimated cost: $1,800-3,200

Typical onset: 90,000-130,000 mi

Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Overheating or fluctuating temp gauge, Milky oil on dipstick or oil cap

Fix: The 3.0L V6 blows head gaskets more than the other engines. Both heads usually need work. Job requires 10-14 hours labor, and you should resurface heads and replace timing belt/water pump while you're in there. If coolant contaminated the oil long enough, you're looking at bearing damage and full rebuild.

Estimated cost: $1,400-2,800

Typical onset: 120,000-180,000 mi

Symptoms: Deep knocking noise from bottom of engine that increases with RPM, Low oil pressure warning at idle when warm, Metal shavings in oil during change, Vibration through whole vehicle

Fix: The 2.5L four-cylinder develops excessive crankshaft endplay and wears main bearings prematurely, especially if oil changes were skipped. This is a full engine teardown or short-block replacement job requiring 14-18 hours. Most owners junkyard-swap a low-mileage used engine instead of rebuilding.

Estimated cost: $2,200-4,000

Symptoms: Liftgate drops suddenly when opened—head injury risk, Latch won't hold gate closed, pops open over bumps, Struts visibly leaking oil or collapsed

Fix: Struts wear out from constant cycling and desert heat accelerates it. Latch mechanisms rust and stick. Struts are 0.5 hour job, latches maybe 1-1.5 hours depending on rust. Multiple recalls on this—check if yours was done. Easy DIY but don't ignore it; falling liftgate has sent people to the ER.

Estimated cost: $120-350

Typical onset: 100,000+ mi

Symptoms: Engine stumbles or dies during acceleration, Hard starting when hot, Loss of power at highway speeds, Whining noise from fuel tank area

Fix: Inline fuel filter rarely gets changed and clogs up, starving the engine. Fuel pump in-tank assembly also fails. Filter is 0.5 hour, but if pump is dying you're at 2-3 hours to drop the tank. Do both at the same time if tank is already down.

Estimated cost: $250-650

Typical onset: 70,000-110,000 mi

Symptoms: Heavy clunk when shifting from Park to Drive or Reverse, Vibration through floor and steering wheel, Visible engine movement when revving in Park

Fix: Front and side transmission mounts crack and separate from the rubber. This puts extra stress on the already-weak A604 transmission and causes harsh shifting. Replacing both mounts takes 2-3 hours. Do this BEFORE the transmission starts acting up to extend its life.

Estimated cost: $200-400

Symptoms: Wipers move slowly or unevenly, One wiper works, other doesn't move or flops around, Clunking noise from cowl area when wipers run

Fix: Plastic bushings in the wiper linkage wear out and fall apart. Takes 1-2 hours to remove cowl cover and access linkage. Not expensive but annoying in rain. Recall campaign addressed some of this—verify it was completed.

Estimated cost: $150-300
