I have a 2000 chevy 2500 work truck with the 7.4l engine. I have been noticing a sloshing noise when pulling out from a stop. I looked under the truck and didn't notice anything out of the ordinary. But when I pull out it sounds like a lot of fluid from the passenger side moving around. Any help in solving this problem would be greatly appreciated.

In the future post this in the appropriate truck forum below, for now find the ac drain usually under the pass. side cowl area and see if is plugged up.

thanks for the info. In the future I will be more careful to post to the appropriate forum.

this sound is usually the coolant flowing thru the heater core...with the engine cold remove coolant cap keep engine running until it is at operating temp ..this should remove the air...if this continues after a period of time[air in coolant ] you will need pressure test...may have a leak..

j cat, reread his post, " sloshing when pulling off from a stop", doesn't sound like something in the cooling system, no?

I seen/heard this before , It was air in the coolant....you get this water rushing sound...when accelerating from a stop..usually when coolant still cold..

Now how did this occur ??? I don't wanna go there..

Yeh, I see the possibility, if we knew some recent history it would help pinpoint the problem, sorta handicapped in this environment.

well maybe he will replly as to what the noise was...normally when the drain is restricted/plugged you get excessive fogging of the windows and the smell of organics decaying..[fowl odors]....

Low coolant level can cause this noise in heater core.
