it sounds like its coming from the motor. im not sure if theres are some air bubles im my motor. what can this bubling sound be. its only when i shut it off. and lasts for a bout a good half a second.

 

coolant?

 

The engine coolant going into the overflow tank is my guess.

 

yea its the coolant. but is this normal? or is it air pockets in the engine?. grr i bled the damn thing alreay but it still does it.

 

are your temps good? thermostat f'ed up?

 

sounds like you are overheating and the sound is your coolant boiling. check to make sure everything in the coolant system is working properly before you drive it again.

 

yup find out why you are boiling your coolant.

 

if 1 peorson said overheat... ok.... if 2 people said overheat.. then you might think about it... but damn near 5 people all agree that your car is overheating....

and i came in to say the same thing, your overheating... im not 99% shur, their have been strange cases.. but im pretty shure your over heating and that you need to get a check up real soon before you blow something...


...goodluck, may the RX-Force b with you

 

Make sure there is absolutely NO air in your system. If your car is an s4, like mine, there are two rad caps and a bleeder. Fill coolant from the upper cap (nearer the t-stat) with the bleeder screw open until coolant weeps from the bleeder. Then close the bleeder screw, then upper cap.

Keep an eagle eye on the temp gauge, there are only three zones- cool(ok) mid range (dood better do something quick) and screwed. If you go above 1/4 past cold, something is amiss, check and re check.

If you have an s5, hopefully someone else more familiar with the setup can chime in here.

 

Mine bubbles after a hard hill climb.

But my gauge rarely moves off of right above the line. The car is a daily driver and I haven't had any problems.

So I'm with OP. Wtf. Lol.

 

might also wanna check the rad cap.if it's old might aswell replace it.pressure keeps the coolant from boiling.old and crappy rad cap might cause the coolant to boil at normal operating temps cause the system isn't staying at the right pressure in the cooling system.air pockets would also be found if the rad cap is bunk.
