On the 1991-1997 Toyota Previa, 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 lifting the vehicle and working from below. Labor costs are significantly higher than typical starter replacements due to access difficulty. Some mechanics refuse the job entirely.

On the 1991-1997 Toyota Previa, 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 the rear seat area and requires significant interior disassembly to access. Many owners bypass the rear heater circuit entirely rather than replace the core.
Pressure-test the cooling system and inspect the rear passenger floor/under-seat heater housing to confirm the rear heater core or its short connecting hoses are leaking; also check for coolant residue at the rear heater pipes before condemning the core. Repair requires draining coolant, removing the rear interior trim/seat area to access the rear HVAC box, replacing the rear heater core and any aged O-rings/hoses, then refilling and bleeding the cooling system; if rear heat is not needed, the supply and return lines can be bypassed with a coupler as a lower-cost alternative. Typical repair cost is about $700-$1,400 because labor is high, while a bypass is often $100-$250.

On the 1991-1997 Toyota Previa, 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 can become completely blocked by 100,000 miles.
Remove and clean the EGR valve and passages. Use a wire brush and carb cleaner to remove carbon deposits from the EGR valve, pipe, and intake manifold EGR ports. Replace the EGR valve gasket. If the valve diaphragm is damaged, replace the entire EGR valve ($100-$200). Clean the EGR system every 60,000 miles as preventive maintenance.
