2007 SATURN RELAY

Typical onset: 80,000-140,000 mi

Symptoms: Coolant loss with no visible external leaks, White smoke from exhaust on cold start, Overheating or running hot, Rough idle and misfire codes after coolant intrusion damages cylinders

Fix: Lower intake manifold gaskets fail first, leaking coolant internally. If caught early, intake gasket replacement is 6-8 hours labor. If ignored, coolant enters cylinders and degrades oil, leading to head gasket failure requiring both heads removed, resurfaced, new head gaskets, and often camshaft replacement due to bearing damage—total 18-24 hours labor.

Estimated cost: $800-1,200 (intake only) or $3,500-5,500 (heads/gaskets/cam)

Typical onset: 70,000-120,000 mi

Symptoms: Transmission fluid dripping near radiator or under engine, Low transmission fluid level on dipstick, Harsh shifting or slipping when fluid gets low, Pink or red fluid mixed in coolant overflow (if cooler fails internally)

Fix: Steel transmission cooler lines rust through where they connect to the radiator. External leaks require line replacement (3-4 hours). Internal cooler failure mixing ATF and coolant contaminates both systems, requiring transmission flush, radiator replacement, and often transmission rebuild if cross-contamination caused clutch damage—total 12-16 hours.

Estimated cost: $400-700 (lines only) or $2,800-4,200 (with trans/radiator)

Typical onset: 90,000-150,000 mi

Symptoms: Loud rattling or knocking from front of engine that increases with RPM, Visible wobble of the crankshaft pulley, Serpentine belt shredding or falling off repeatedly, Check engine light with crankshaft position sensor codes

Fix: The rubber ring inside the balancer separates from the hub, causing severe vibration and risk of crankshaft damage if the outer ring flies off. Replacement requires special puller and installer tools, 2.5-3.5 hours labor. Must inspect crankshaft nose for damage.

Estimated cost: $450-750

Typical onset: 60,000-110,000 mi

Symptoms: Power steering fluid leaking onto ground from bellows boots, Groaning noise when turning at low speeds, Increased steering effort or wandering, Steering pulls to one side

Fix: NHTSA recall 14V-053 covers rack and pinion seal leaks. Dealer may replace free if still covered. If paying out-of-pocket, rack replacement is 4-5 hours labor. Check recall status by VIN before paying—many owners still unaware of this.

Estimated cost: $0 (if recall) or $800-1,200 (aftermarket rack)

Typical onset: 80,000-130,000 mi

Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive engine movement visible when accelerating, Vibration through floorboard at idle in gear, Difficulty shifting smoothly

Fix: Hydraulic transmission mount fails internally, allowing powertrain to move excessively. Replacement is straightforward but requires supporting the transmission, 2-3 hours labor. Often both engine and transmission mounts need replacement together.

Estimated cost: $350-600 (one mount) or $600-900 (both)

Typical onset: 100,000-160,000 mi

Symptoms: No-start or extended cranking before starting, Engine sputtering or dying during acceleration, Loss of power on highway, Whining noise from fuel tank area

Fix: Fuel pump module inside tank fails. Requires dropping the fuel tank (easier with tank near empty), 3-4 hours labor. Filter is part of the pump assembly and not separately serviceable—full module replacement required.

Estimated cost: $700-1,100
