 No, passenger, passenger, right. Yeah, okay, passenger side. But that is the radiator cap, correct? Correct. Right, yeah. So take that cap off. Make sure it's got the correct amount of coolant in it. Crank it over and watch the bottle. Do you see any signs of bubbles? Don't be looking in the bottle directly because you may get a bath. Does it actually push coolant out of the bottle? All right.
