What is the 2002-2005 Chevrolet Cavalier 2.2L Ecotec Coolant Leak and Thermostat Housing Crack?

The 2.2L Ecotec engine develops coolant leaks from the plastic thermostat housing, water outlet, and coolant elbows. These plastic components crack from heat cycling. Repairs typically run $150-$500. Severity: medium.

What is the 1995-2005 Chevrolet Cavalier Lower Intake Manifold Gasket Coolant Leak?

The 2.2L and 2.4L engines in the Cavalier are prone to intake manifold gasket failure, allowing coolant to leak externally or internally mix with oil.

What is the 2002-2005 Chevrolet Cavalier 2.2L Ecotec Water Pump Seal and O-Ring Failure - Coolant Weep and Oil Contamination?

The Ecotec's water pump is driven off the timing chain end of the engine and sealed to the block with a molded O-ring that also separates the coolant passage from engine oil. Two failures are documented on J-body forums: the pump's shaft seal lets go and coolant weeps from the dr… Repairs typically run $350-$1,300. Severity: medium.

What is the 1999-2005 Chevrolet Cavalier Front Strut Upper Mount and Spring Seat Squeak / Memory Steer (TSB 04-03-08-015B)?

The front strut upper mount and its spring seat bearing bind as they age, producing a squeak, creak or groan from the front end when the wheel is turned at low speed, plus a clunk over bumps and a 'memory steer' feel where the wheel does not self-center after a turn. GM acknowled… Repairs typically run $200-$600. Severity: medium.

What is the 1995-2005 Chevrolet Cavalier In-Tank Fuel Pump Module Failure - Whine Then Crank-No-Start?

The in-tank electric fuel pump module is a routine wear-out item on the 1995-2005 Cavalier and typically announces itself with a loud whine or high-pitched buzz from under the rear seat before it quits. When it fails the engine cranks normally with no sign of firing. Intermittent… Repairs typically run $250-$850. Severity: medium.

What is the 2002-2005 Chevrolet Cavalier 2.2L Ecotec PCV System Clogs - High Oil Consumption, Blue Smoke and Blown Rear Main Seal?

The L61 Ecotec integrates its crankcase ventilation into the camshaft cover with a fixed orifice rather than a serviceable valve. When the passage sludges over, crankcase pressure has nowhere to go: it forces oil past the rings and into the intake, giving high oil consumption and… Repairs typically run $100-$1,000. Severity: medium.

What is the 1995-2005 Chevrolet Cavalier Water Intrusion Into the Cabin - Rusted Cowl Corners, Blocked A/C Drain and Trunk Seals?

Soaked carpets are a signature J-body complaint and owners trace them to several specific places rather than one. The most damaging is rust perforating the far corners of the cowl panel under the wipers, which lets rainwater run straight down onto the front floor pan. Sunroof-equ… Repairs typically run $50-$800. Severity: medium.

What is the 1995-2005 Chevrolet Cavalier Rear Drum Brake Wheel Cylinder Leaks or Seizes - Soft Pedal or Dragging Rear Brakes?

Every Cavalier of this generation uses rear drum brakes with a cast wheel cylinder that corrodes internally, especially on cars in salt states and on cars whose brake fluid has never been flushed. Two outcomes are common: the cup seals let go and brake fluid soaks the shoes and t… Repairs typically run $150-$450. Severity: medium.

What is the 1997-2005 Chevrolet Cavalier Instrument Cluster Gauge and Backlight Failure - Dead Speedometer, Pegged or Erratic Needles?

Cavalier and Sunfire instrument clusters fail in two distinct ways as they age. On the 1997-1998 cars the failure is usually cracked solder joints on the cluster circuit board and dead backlight bulbs, giving intermittent gauges and a dark dash at night. On the 2000-2005 clusters… Repairs typically run $25-$300. Severity: medium.

What is the 1995-2005 Chevrolet Cavalier Blower Motor Resistor Burns Out - Heater Fan Works Only on High?

The Cavalier's HVAC blower speeds below high are routed through a resistor pack mounted in the heater case in the passenger footwell. High speed bypasses the resistor entirely on its own relay-fed circuit, so when the resistor's coils burn open the fan works only on the highest s… Repairs typically run $15-$180. Severity: low.
