What is the 1991-1997 Toyota Previa Head Gasket Failure on the 2TZ Mid-Engine (Overheating-Induced)?
The 2.4L 2TZ mid-mounted four-cylinder is prone to head gasket failure, and the risk climbs on the 1994-1997 supercharged 2TZ-FZE where added boost/heat accelerates wear. Failures cluster around 100,000-150,000 miles and are almost always triggered or worsened by the Previa's mar… Repairs typically run $1,800-$4,000. Severity: high.
What is the 1991-1997 Toyota Previa Complex Cooling System: Long Pipes/Hoses, Clogging and Overheating?
The mid-engine layout forces coolant to travel from under the front seats to the front-mounted radiator and heater core through unusually long metal pipes and rubber hoses. This large, hard-to-bleed system is prone to air pockets, sludge/sealer clogging of the radiator and heater… Repairs typically run $250-$1,600. Severity: high.
What is the 1991-1997 Toyota Previa Difficult Starter Motor Access and Failure?
The Previa mid-engine layout places the starter motor in an extremely difficult-to-reach location beneath the passenger compartment floor. When the starter fails (common at 100,000+ miles), the repair requires removing the passenger seat, cutting an access panel in the floor, or… Repairs typically run $500-$1,200. Severity: medium.
What is the 1991-1997 Toyota Previa Rear Heater Core Leak?
The Previa features a rear heater system for passenger comfort, and the rear heater core is prone to developing leaks due to corrosion and age. Coolant leaks onto the rear floor area, causing carpet damage, mold, and a sweet antifreeze smell. The rear heater core is located under… Repairs typically run $300-$1,200. Severity: medium.
What is the 1991-1997 Toyota Previa SADS (Separated Accessory Drive Shaft) Flex-Coupling Failure?
Because the engine is mid-mounted but the accessory belts/pulleys are at the front, Toyota used a long accessory drive shaft (SADS) with two rubber flex couplings to connect them. The couplings deteriorate with age and mileage, producing vibration and rattle and, if ignored, can… Repairs typically run $300-$1,200. Severity: medium.
What is the 1991-1997 Toyota Previa Ignition Misfires: Distributor Cap/Rotor, Plug Wires and Distributor Oil-Seal Contamination?
The 2TZ's distributor-based ignition is a common source of rough running as the van ages. Spark plug wires crack and corrode, and the cap and rotor burn/wear, causing misfires and rough idle. A distinctive Previa failure is oil weeping past the internal distributor oil seal, whic… Repairs typically run $150-$700. Severity: medium.
What is the 1991-1993 Toyota Previa Windshield Wiper Motor Failure (NHTSA Recall 93V-113)?
Early Previas were subject to NHTSA recall 93V113000 (issued July 1993, ~75,863 units) for a windshield wiper assembly/motor that can fail and stop the wipers entirely, causing sudden loss of visibility in rain or snow, a safety hazard. The affected components lacked sufficient s… Repairs typically run $150-$450. Severity: medium.
What is the 1991-1997 Toyota Previa EGR System Carbon Buildup Causing Rough Idle and Stalling?
The Previa's mid-mounted 2TZ engine is prone to severe EGR valve and passage carbon buildup due to its unique layout and higher operating temperatures. Carbon accumulation restricts EGR flow, causing rough idle, hesitation, and stalling. The EGR passages in the intake manifold ca… Repairs typically run $100-$400. Severity: low.
