Fluid noise from dash?

I hear a sloshing noise coming from the dash when I accelerate early in the morning. Any clue how to get rid of it?

 

Any leakage into the cab? Sweet smelling its antifreeze. Brown rain water, check for leakage from windshield also check if your AC drain could be plugged.

 

No leaks inside the cab. Sounds like coolant. Only for about 10 minutes and when accelerating from a stop sign.

 

I had this in my gen 2, gurgled a bit, got used to it!

 

Recently I accidentally broke the antenna off attempting to straighten it out. Thus no radio to drown out the noise. Changed out the radiator cap thinking it may be sucking in air at night when the engine and fluid cool down. That didn't work. May try to burp the system.

 

I recently changed my radiator fluids, and I have had a gurgling sound ever since. I have run the engine with the radiator cap off and allowing the water to run through and some bubbles came out and added motor radiator fluid. Couple days later, same thing happened so I did the same thing, ran the motor with the open cap off and even more bubbles came out. Couple days later, things seem to be fine, but nope. I have changed the entire catalytic convertors. Tighten all the heat shields, replaced one of the O2 sensors, changed the spark plugs (recommended by my Tacoma manual for my high mileage). I read that maybe it's my muffler, but the sound is coming from the front of the truck, not the rear. I even cleaned the AC evaporator by using vinegar and water and used a garden pressure sprayer and flushed out the AC drain and whatever crap that flowed out. Well, now the AC water drains like it should, but still the gurgling noise.

Anyone?

 

Condensate in the AC box?

If so, clear the drain.

It's that time of year.

 

Coolant could be low...

 

As I wrote in my thread, I have let the truck run with the radiator cap off and allow it to clear what ever bubbles that may be still in the system. I did this twice. It seem to work but only for a short time.

 

Use a spill-free funnel?

v6? head gasket?

 

^2005 double cabs were only available as V6.

Head gasket leak would cause bubbles and outgassing continuously and not cease. That doesn't match @cb2xs' description, where the radiator appears to be bled, then air reappears after some time. I suspect there's a cooling system leak somewhere.

 

This was the first symptom of my head gasket going so it’s possible
