Bad Intercooler Pump

[JayLo]

Ok, so my 48k mile Syclone seems to be considerably down on power ever since I got it a couple of weeks ago. Come to find out, as well as a tune up, it also needs an intercooler pump. The original Bosch pump is completely seized.

I'm also not getting power to the pump, so I think I'll check the fuse. Any ideas where that is located? I dont seen anything by the alternator.

I ordered a replacement pump from detroitturbo.com. Any guess as to how much if any this will help liven the currently non-intercooled slug up?

No way is it the 4.9 to 60 or low 14 second truck it should be for the miles it has.

Re: Bad Intercooler Pump

the cooler IC temps definately improve performance.

the fuse is right on the back of the alt.. in a little black plastic clip thingy.

Re: Bad Intercooler Pump

the dipstick shouldn't pop underboost either

Haha. That was in reference to the old, well worn bottom end in my R/T. Thank God I don't have 187k on my Syclone. :tup:

The IC will at least give you .2 to .3 on your ET and 3-4 mph.

Hotwire your pump and do the 3/4” lines while you are at it.

If the fuse is good get a new relay. It's like $10 or so. Take the part # off the top as the dealership does not know what it is.

Sounds like you are not boost launching as the IC will not have much effect on 0-60.

Though I don’t recommend this until you get your IC fixed because you truck is probably knocking like crazy at wot.

edit
I used clear hose from the upper IC to the fender to help get the air out, but make sure you use distilled water so the clear lines stay nice and clean.

Also, boost launching will probably shorten the life of your transmission.

I don't know if this is before or after your 'no boost' post, but a bad IC leads to high Manifold Temps, which leads to knock, which leads to less timing which leads to really-friggin-slowness.

Re: Bad Intercooler Pump

This may be a dumb question but how can I tell if my intercooler pump is working? I've just replaced the old bosch with a johnson intercooler pump but I can't actually tell if its working or not. I just got the truck running but its only been idle I haven't actually taken it out for a spin yet. Is there an easy way to find out if my pump is actually flowing or not? Thanks for any advice.

If you turn your key to the on position but don't actually start your truck.. then get out and listen you an hear the pump working.. and you'll also hear a clicking sound of the iac I believe. You could always check to see if you have power at the pump with a tester with the key turned on but the motor off. Also if you look inside the upper ic you should see slight movement of the liquid.

The method to check it is as follows. With the key to the "ON" position, take a paper clip and jumper the"A" and "B" terminals on the ALDL connector under your dash. In addition to making the IC pump run, this will also flash any trouble codes stored in the ECM. I like to pull off the cap so that I can see that the coolant is actually swirling around in there when performing this test.
