Lately ive been noticing that my intercooler system isnt flowing at all through the filler cap. Ive made sure that the heat exchanger is hooked up correctly, but i noticed something interesting. When I force it on via hptuners i hear my pump run and i can feel flow in the hose going into the intake manifold, but there is no flow at all in the hose that comes out of the IM and through the filler neck. My question is that is it common for these to clog up and block flow completely? If so Im just going to get new ones or clean mine and get a dual pass since ill be in there anyways.

Thanks in advance guys

 

i would think if it was clogged then i would back up all the coolant... and go someplace. so i doubt that.

maybe ur pump is taking a ****? idk, u can see it flowing with hptuners? but not with just the car

 

Well the pump is brand new and I can hear it flowing a bit and feel water moving through the hose going to the IM but nothing is going through the filler cap. It must be getting backed up going into the IM

 

what are your ait2s

 

Remove the bottom hose.

Does water flow out from the pump?
If no replace ur pump, if yes;

put hose back and remove top hose, does water flow out of the manifold?

If no, than remove intake manifold and inspect the cores. If yes that check ur hoses to make sure none are plugged

 

Did a 55-100 3rd gear pull yesterday in 52 degree weather and IAT2 started at 75 and climbed to 115 by 100mph. This is with no meth, so ignore my signature.

Looks like im gonna have to make a mess on the floor and start pulling hoses

 

ha ur in good shape bud, my iat2 when its 33 outside sit about 100 while driving and jump out the roof when i get on it.. my pump just completly went out. its got 12 volts coming in, i punched it with my fist then hit it with a hammer and it started to flow then seize up again..piece of crap plastic pumps.

 

Yeah i guess the numbers seem right. I made sure everything was flowing today by taking off each hose and they flow, but when I do it with hptuners if the Key has been in the ignition for a while the battery starts to drain, thats why it didnt flow before. Now I need a new battery

 

How do you check IAT ? with a scan tool or is this a gauge I don't know about?

 

Yes scan tool, get one of those app dongles they're affordable. I swapped to a 4-bar w/ built in IAT sensor with my M62 swap, IAT is right near Cylinder 1 head port after the laminova intercooler cores.

 

Hello thanks for your reply, There is a IAT port near Cylinder 1? on the head or the manifold? if so,, can I put a sensor to a gauge at that port?

 

You can get an aeroforce gauge that will show it from the obd port, or like steelmesh said, get an obd blutooth dongle and download an app that will show live data on your phone.

 

No, your car won't run right without the map and IAT sensor functional. I was just pointing out the IAT location to confirm that it was after the intercooler in case that was a curiosity.
