Default Sloshing sound

I've noticed a sloshing sound everytime I drive. It's very consistent, everytime I drive off it sounds like water's running out of a hose or something.

Today I did a test, put it in N and kept it at 1500 rpms, keeps hearing that sloshing sound. The car isn't moving though.

Anyone got an idea as to what it may be?

Air trapped in the cooling system and heater core? Check whether the coolant level is low in the radiator and reservoir.

most likely water running through your cooling system into your heat core/ ac

I hear it more when ac/heat is on, so that makes sense. How do I fix it, drain all the coolant and refill?

I just checked it, the overflow container is wayyy below the "low" line, should I add more antifreeze?

When the engine is cold, top off the coolant in both the radiator and the reservoir. Then bleed the system as detailed in the service manual.

Thank you, I'll do it tomorrow. Would that make any difference in performance at all? I've been getting 22 mpg for a while now and I can't seem to figure out what's wrong...my dad hasn't done anything to this car for 3 years now - only oil changes.

It's possible. If air gets trapped around the coolant temperature sensor under the distributor, then the ECU will receive false temp readings that could might make the engine run rich.

I have had the same noise. It sounds like fuel rolling around in the tank. My garage who deal with Saabs mostly, said it was likely to be a blocked drain from the air con. It turns out that the suspension was damaged and the air and oil were creating the noise as it was moving. Really odd but now fixed. As it happens my calliper had also seized as well as other things, so my bill ended up at twice the value of the car. Still, got to love your Honda right?!

Maybe i'm daft but "the suspension was damaged and the air and oil were creating the noise as it was moving" doesn't make sense to me.

P.S this thread is seven years old. You're suppose to have a good reason to bump an old thread, not.. whatever that was.

Hi Hondur - the oil and air mixing together (due to the suspension being broken) were making a noise when the car was moving, so I thought this would be useful to others as it appears another actual reason for the sloshing sound. I therefore thought this would be a valid reason to post. There may be other Honda's out there with a similar problem.
