On my '96, the reservoir is indeed on the right (passenger) side of the car.
And I'm darned if I can find a radiator cap on the radiator. It's the only place
I've ever put coolant, and it's where I added some liquid based stop leak stuff.
Perhaps one of the others can illuminate us a bit.

Open the radiator cap when engine is cool. Coolant should be right at the top. If the cooling system is healthy, the coolant reservoir will keep the system full.
On mine, it's right next to the shifter. Yellow cap. I think it says "oli" which is a little confusing.
under the front hood, behind the spare tire. right next to the washer fluid reservoir.
On a 1996 Ford Escort : The power steering fluid goes in the power steering fluid reservoir , at the front of the engine compartment , on the passenger side of the vehicle ( looking from the front of the vehicle it is the reservoir on the RIGHT) * With the 1.9 liter engine the reservoir on the left is the engine coolant reservoir and with the 1.8 liter engine the reservoir on the left is the windshield washer fluid reservoir , but with both engines the power steering fluid reservoir is the container to the RIGHT , looking from the FRONT of the vehicle
On a 1998 Mercury Tracer : The power steering fluid reservoir is at the front of the engine compartment towards the passenger side < of the vehicle ( when looking from the FRONT of the vehicle , the power steering fluid reservoir is the reservoir on the RIGHT )
On the coolant reservoir. This is a plastic reservoir toward the back right of the engine compartment.
Right on top of the pump. It looks like a European style cartriage oil filter container. But its actually the fluid reservoir. Choosing the right fluid is the tricky part.
The power steering reservoir is located below the back, right side if the engine. First, remove the two screws that mount the antifreeze reservoir, lift it up (with hoses attached) and move it toward the radiator to make room to reach the power steering reservoir cap. Then, reach down the back, right side of the engine with your right arm to find and remove the power steering fluid reservoir cap. Check fluid level carefully (relative to present engine temperature). If fluid is low, a small thin funnel will help to add fluid without spills (NEVER OVERFILL).
Just in front of the radiator overflow container, behind the right headlight, is another white plastic container. This is the PS fluid reservoir. Marks for "full" and "low" are on it. The cap simply twists off.
The reservoir cap (that's about all you can see of it) is in the front of the engine compartment, in front of the radiator cross brace, on the drivers side of the car just to the right of the radiator.
The clutch fluid reservoir is on the firewall, in front of the driver, immediately to the right of the brake booster. The fluid should be clear, and at the appropriate level as indicated on the side of the reservoir.
To fill the brake fluid in a 2001 Honda Odyssey, you need to find the brake fluid reservoir and remove the cap. Fill the reservoir with the right amount of fluid and put the cap back on.
