Replacing Prius coolant on level ground

Scope out the location of the plugs that you need to access.
You might be able to reach them without any ramps.

THEN.....you can loosen the necessary plugs but not open them fully until you take it back down OFF the ramps to drain.

 

you will need jack stands, it is not for the feint hearted

 

In my case I needed to take the under engine covers off and that is hard enough even on jack stands or ramps. The covers have pushpin and screw fasteners. Then the radiator peacock is easily accessible. Be prepared with a few new pushpin fasteners for reassembly.

I don't think level is all that critical since the engine coolant won't all come out anyway.

 

The engine coolant can be drained without raising, though it is easier access if raised. The inverter you pretty much have to raise. You can close everything up and refill with car on ground, level.

all that said, I don’t think it has to be level.

definitely watch @NutzAboutBolts videos. They’re linked at top of 3rd gen maintenance forum.

 

I'm pretty sure car doesn't need to be level for coolant drain. You won't be draining 100% of the fluid anyway.

A floor jack and stands are a must for any DIYer anyhow so I'd pick some up. They'd pay for themselves the next time you rotate your tires and service your brakes.

 

You can get them cheaply at the dealer. If the dealer is nearby, you can wait until you know which push pins break.

These are on my car for item 3:
