"liquid" sounding clunk shortly after start up
'98 4runner Limited, 203k miles. About 15 seconds after I start the 4runner, I'll hear what sounds like a liquid clunking sound coming from the passenger side of the engine bay. a/c compressor is off. I was initially thinking maybe coolant bubbling through the heater core, but I've flushed the cooling system a few times and just put a new radiator in.
My other thought is maybe something in the power steering rack? I'm at a loss, any leads?

The splashing sound I'm hearing sounds more like the viscosity of coolant or washer fluid or something, not something more viscous like brake fluid. Also I think the master cylinder is in front of the driver.

Any chance it's the rear heater core under the passenger seat?

Does it sound like trickling water? Mine does it too when the temperature outside drops. I replaced my be radiator last year and it started doing it right after. There have been other posts on it and apparently there's an air bubble in the cooling system somewhere.
I drove my front end on ramps, took the cap off, let it run and get up to Temp with heat on for the front and back seat and I still couldn't get the bubble out....

Nope, it's like one sudden "clunk", like dropping a rock in a bucket of water.

That's an odd one.
Does the sound happen once upon startup or does it repeat as the vehicle is thinking? Then does it slowly go away?

Could it be the normal self-test performed by the ABS device under the hood? On mine it happens at about 5 seconds after I turn the ignition on, whether I immediately start the engine or not. It's probably not loud enough to hear once the engine is running, though.

Possibly your blend door/blend door actuator arm making the noise. Does your air channel to the multiple locations available on your climate control system. For example switch from feet, to face, to defroster?

all of that seems to work fine, that also wouldn't explain the liquid splashing sound

When you filled your coolant did you use a spill free funnel and elevate the front end?
