2002 FSO POLONEZ

Typical onset: 40,000-80,000 mi

Symptoms: White smoke from exhaust, especially on cold start, Coolant loss with no visible leaks, Overheating under load or in traffic, Mayo-like sludge on oil filler cap, Rough idle and misfire codes

Fix: K-Series engines have thin block decks that warp easily. Head gasket replacement requires head removal, resurfacing (almost always warped), and often new head bolts. Plan 8-12 hours labor. Many techs also replace the thermostat and water pump while in there. Use MLS gasket upgrades if available.

Estimated cost: $1,200-2,200

Typical onset: 60,000-100,000 mi

Symptoms: Loud ticking or tapping from valve cover, worse when cold, Ticking that doesn't quiet down after 30 seconds of running, Loss of power and rough running at higher RPM, Metal shavings in oil during changes

Fix: K-Series and Fiat 1600 engines both suffer from lifter collapse due to poor oil quality or infrequent changes. Requires camshaft removal to access lifters—typically 6-10 hours labor. Camshaft lobes often show wear and need replacement simultaneously. Must use correct spec oil (5W-30 semi-synthetic minimum) post-repair.

Estimated cost: $800-1,600

Typical onset: 50,000-90,000 mi

Symptoms: Severe clunking when shifting from Park to Drive or Reverse, Excessive engine movement visible from engine bay during acceleration, Vibration through shifter and center console, Grinding or scraping sounds over bumps

Fix: Rubber mounts disintegrate due to heat and poor material quality. Front and rear transmission mounts fail together about 70% of the time. Replacement requires lifting the transmission slightly—2-3 hours labor for both mounts. OEM replacements are scarce; aftermarket polyurethane upgrades last longer but increase NVH.

Estimated cost: $250-500

Typical onset: 70,000-110,000 mi

Symptoms: Serpentine belt shredding or throwing off repeatedly, Vibration felt through steering wheel at idle, Wobble visible on crankshaft pulley when engine running, Check engine light with crankshaft position sensor codes

Fix: The rubber ring between inner hub and outer pulley deteriorates and separates. Can cause timing issues and accessory belt damage. Requires special puller tool and careful installation to avoid crankshaft seal damage—3-4 hours labor. If it fails completely while driving, can damage front main seal and cause oil leak.

Estimated cost: $350-650

Symptoms: Hard starting or extended cranking, especially when hot, Surging or hesitation during acceleration, Stalling at idle or when coming to a stop, Loss of power above half throttle

Fix: Fuel tanks rust internally, sending debris through the system. Fuel filter clogs quickly (should be changed every 15,000 mi, not the factory 30,000). Severe cases require tank removal and cleaning or replacement, plus injector cleaning—4-6 hours total. Always replace filter AND inspect tank condition when troubleshooting fuel delivery issues.

Estimated cost: $200-800

Typical onset: 80,000-120,000 mi

Symptoms: Transmission fluid leaking near radiator area, Pink or red fluid mixing with coolant in overflow tank, Slipping or delayed engagement when transmission overheats, Burnt transmission fluid smell

Fix: Steel cooler lines corrode where they connect to radiator or clip to chassis. If cooler inside radiator fails, transmission fluid mixes with coolant and destroys both systems. Requires line replacement and often transmission fluid flush—2-3 hours labor. If cross-contamination occurs, budget for radiator replacement and transmission rebuild.

Estimated cost: $300-600 (lines only); $2,500-4,000 (if contaminated)
