how do you know? i have tried to search but got nothing.... help me out. i think mine stops working occasionally.

 

Car is running. Open hood, Open cap to IC system. Verify coolant is flowing. If not moving, it's not working.

May be hard to tell if your neck is 100% full, but look for bubbles if thats the case.

 

ok i replaced the pump today and car runs a lot better (i guess not heat soaking as much) and i took a look at what you ^ said and it looks as if it isnt really flowing but i see little bubbles (not a lot) you think maybe since i have the zzp heat exchanger and the stock one working together, it isnt flowing as fast as it did with just the stock?

 

Do you by any chance have an interceptor gauge? If you do watch your iat2's. If they raise extremely quickly when your WOT then the pumps probably out. It's really common on these cars for the IC Pump to fail. Basically from what others have said, metal flakes or shavings get stuck and it seizes up. Moral of the story replace it if its not working lol. But as the guy above said take a look at the filler neck and see if you can see bubbles or any type of movement or flow of liquid. If you see no bubbles/flow then it needs to be replaced ASAP. It's really important to have a working pump because to high of iat2's can cause your number 4 piston to go bye bye, and thats no fun lol.

 

i have no interceptor but want one really bad. does anyone happen to know where i can get a cheap interceptor?

 

Check the classifieds or ebay or ttr or ottp.

 

Well let's put it this way...my last cobalt I ran for over a year on stage 2 with no pump and I drove the hell out of it. Never blew anything. And it's hot as hell down here in FL. There are parameters in the tune that cut boost if the IAT2s get too high, as a provision to keep from blowing the motor.

 

thanks for the info. whats up with this "hammer mod" thing???

 

Lol...if you think your pump isn't working, try tapping on it with a hammer on the plastic end where the hoses connect. You can also tap on the metal bracket that holds it on the car. If you can get close enough to it, you can hear the pump whine while it's running. It's just plastic shavings on the inside that clog up the magnets...tappin on it breaks them loose and makes the connection again.

 

oh nice lol. i just replaced mine thinking it was bad and it seems to be working just the same as the other one but i noticed a HUGE + power difference from the old.

 

with no interceptor to tell, it was probably going out or gone. Hammer mod may have got you some more time out of it. the parameters in the tune cut boost to 80% when the IAT2s get to 207*. When I finally figured out that my pump was out in my old car and replaced it, it was like a whole new car.

When the pump decides to crap out in this cobalt, I've seen temps shoot as high as 170's on a quick WOT pull. From what I've seen, IAT2's should NEVER be over 140 unless you are riding the **** out of the car constantly, doin consistent pulls, etc.

 

think if i just take my car in to the chevy dealer and tell them to cheeck if its not working i only have 34,500 miles should get it replace for free right?

 

should. dont see why not. i just dont trust the stealerships all that much

 

yeah but right now i have a hole in my downpipe and i wont be able to install my header and downpipe tell i go home in may so im going to go the the dealership and see if they wont replace my pump and maybe ill get lucky and get my dp replaced untill then too b/c i cant stand how my car sounds right now!!

 

lol that must suck. hope you get that all fixed up soon

Ford Racing used the EXACT same Bosch Pump that is on our cars, for the Cobra and Lightning.

 

yeah me too!! i plan on takin my car in tomorrow

 

just got one just like that from blueovalparformance. it was 100 shipped on ebay.

 

did you get just a stock replacment or did you get an upgrade?

 

im guessing its the stock replacemnt. but its for a 03-04 cobra. and when the hell are you gonna hang out with the car club?

 

lol i really dont know man im aways scheduled to work on friday nights and saturday at noon it sucks

 

A 'Cobra Intercooler Pump' is the same thing as the 'Bosch Intercooler Pump' that is used on our car, and is generally $35 less.

The easiest way to see if it's working is to take a simple drinking straw, put it in the fill neck and see if it gets tossed around from the fluid flow.

 

I agree.. I used a flat head screw driver to check mine, if it sucks it to the side.. it's flowing

 

sweet ideas! thanks guys

 

dang im going to have to try a few of these now i forgot that its 2009 and my car is an 05 so my warrenty went bye bye and i can no longer get my last few things i wanted warrenty to fix like replace this pump fixing the passenger window
