I'm no mechanic but you might have so air getting somewhere it doesn't belong. Like an open cap or something.

But I really don't know.

 

i'd sugguest you have air in your radiator

replace radiator fluid or just let the air out and make sure all the coolent is at all the right levels

 

try to make the noise happen by changing the engine speed.if there is air in the cooling system you are hearing the coolant slushing around as it enters your heater core.

 

do a search on "burping" your radiator.

once you let the coolant level fall below the level of your upper reservoir, you must add more coolant while "burping it".

for old bmws, it meant squeezing the air out of the hoses while adding coolant.

 

jkwon, korean? anyways i am lol
well i had the same problem, daredevil repsonded to my post about that, i went to the dealership mod friendly, and they just replaced the radiator. The gurlging noise is due to leaky radiator. If your not sure look at the top of your rad. and see if there is dried coolant on the top look underneath the front air scoop thingy also. pm if u have any other questions

 

that is what that noise is? i have had my 95 L for two years now and has do that about a week after i got the car and i have a new radi

 

yeah go to mod friendly find one, come to kali lol

 

i've heard the noise in my 02 wrx. I think the noise is the coolant starting to flow when the thermo opens up.. i may be wrong. i hear the gurgling after 2-3 min warming up.

 

what ever it is i dont think it will hurt the car as long as you keep coolant in the radi

 

air in the radiator take your cap off and pump the radiator hose (big black one coming from the top of the radiator ... to burp it... then refill

edgar,
i dont think you need another radiator but if you have air in your engine you might fry a piston!!

 

hey jkwon, i just my car kixed for that same reason, my happy friends at South Coast Subaru told me it was the muffler. If you have a stock muffler look at the two tips. there is two small little holes. Some how they get pushed out and when that happens and u rev the exhaust whistles through those little holes. But it sounds like it is from the engine bay which is what i thought. So they just pushed it back in for me. And low and behold it went away. Hope that helps.
