im driving a old 89 toyota cressida. i got this little noise problem, but so far i dont know why it happens and it looks like its not effecting the car anyways. heres my situation
1. happens in cold weather (mornings, night)
2. when i give it a little gas, i can hear this wooshing/gargling sound. i think its most likely being the collant.

example: ill start my car in the mornings to go to school and ill back up my driveway. as i give it a little gas, you can hear the collant(maybe) being gargled/wooshing around. once i hit higher throttle, or rpm, it fades away. then ill come to a stop sign and acclerrate, again i can hear the wooshing/gargling sound comming from the engine. but once the engine is all nice and warmed up, the noise thing goes away.

im i missing a chuck of knowledge about motors? is this a major problem? whats going on. can anyone shed some light onto this. its like a mystery for me.

 

you are probably low on coolant, this will cause your heater core to become low on coolant and you'll hear it sloshing around.

 

My WRX has done the exact same thing on a few ocassions. Topping off with distilled water and/or coolant makes the problem go away. You probably have a little bubble in your system, and once the temp/pressure goes up in the system, you no longer hear the noise.

 

i have the same problem with my 00RS. but after I topped off the coolant at COLD temp, I would still get it from time to time...
