What is that thing next to the (right) battery on a Toyota previa?

Question

That black box thing and where is the spark plugs,alternator,timing belt,spark plug wires located on a 91 - 97 toyota previa?

Answer 1

The motor is under the car, To access the Spark plugs you need to remove the pass seat, pull back the carpet and remove the floor pannel.
Is it Supercharged?
The Black Box probabley is your air filter box.
There is no Timing Belt, it is a chain.
You must be new the Previa, You do know to check the oil you need to flip the Drivers seat back and remove the panel under it.
That is how you fill the oil and chaek the trans fluid.
All the stuff under the hood is just run off a power take off from the motor, That is your AC, Alt, PS Pump, and Supercharger if it has one.
The Water Pump is on the motor next to the Ol Filter, under the floor between the seats, you need to lift the van up to access all of that
