Thread: Engine Compartment Sound/Noises I need diagnose ASAP!!!

Hey guys

Well as of right now I have a couple engine sounds that are starting to worry me. They dont effect the running ability of my car, but they are just annoying.

1) I have a high pitched sloshing sound coming from the bottom of the car (sounds like radiator or Rad lines). I just had my LIM-Gaskets replaced, so my coolant system was drained & refilled. The sound starts about 30 seconds after the car is turned on & it sounds like water being sloshed between drain pipes. It has been doing it ever since I bought the car. So even before I had got the LIM-Gs replaced it was doing it. My temp was reading normal (well not it not because my ECTS is deleted because its broken.)

2) I get this other sound on occasions (when the car has been driven for a while). It kinda like a squealing/screeching sound. It travels with the engines RPM until it reaches about 2k & it stops. Once you drop below 2k it starts again. It sounds like its near the alternator & supercharger. I have a video of what it sounds like (this is not my car, but it sounds exactly like YouTube - noise in belt system.


So any help would be greatly appreciated. I am going to try to take it to my mechanic today & see whats up

Take the blower belt off...see if it keeps doing that. If it does...then it isn't blower related. If it DOES stop...then you need your supercharger serviced and possibly rebuilt. As for the latter...could be a bad Alt. pulley...they tend to squeak and stuff. Try spraying WD40 on all the pulleys and tensioners

I got a vid of the slushing sound, but I didn't get that squealing sound. This is crappy audio (Did it on my HTC Touch Pro) so some sound will sound wierd. Although the PS pump whine & pulley squeak is there. You hear a gurgling sound between 1:20-140. The sloshing sound doesnt start until 1:40, it on the passenger side of the radiator. Oh & ignore my face in the middle of the vid haha & that is NOT how I look if you me on the street lol.

So that sloshing & gurgling sound could be from the pulley system? & I looked up on the screech noise & the guy on youtube said that is was a problems with his PCV system
