Coolant Spraying from the Supercharger Reservoir

[04_Yellow_Cobra]

2004 Cobra w/ CAI, 2.80 pulley, and diablosport handheld tune, 13-15 PSI

Runs great but when I get above 10 PSI and stay in it for a few seconds coolant sprays out of the reservoir cap out of the heat extractor on the hood. Ive made sue that the pump is circulating like it should. Ive talked to several people and no one has experienced this issue, at least not that ive found. Couldit be my cap is not holding its seal? Or could i have a bigger issue? Ive been told it could be a crack in my intercooler but I dont know and I dont want to just start throwing money/parts at it. Any help is appreciated.

Could be a blown head gasket. This happened to me. My car was fine till I got on the boost come to find out the it was pushing air into the coolant system. I had no coolant in the oil. I found it when I pulled my plugs I had coolant all over the #7 coil. Hope this helps. These cars blow head gaskets and not every symptom for it is the same. Thought he was talking about the coolant res my bad

isnt the coolant for the blower separate from the engine coolant?

a blown head gasket can pressurize the coolant tank but to the best of my knowledge cannot pressure the intercooler circuit.

If you are SURE the fluid came from the intercooler tank Id keep a good eye on the intercooler pump, they can work intermittently (bumps can make them start/stop), after that Id suspect the cap

I would check the intercooler reservoir for a crack at the base of the neck where the cap screws on. Small crack there on my brother in laws 03 caused the exact same symptoms that you described.

Im 100% that its the Intercooler reservoir. Ive checked the pump a few times and its been working each time ive looked but i will keep checking it.

I ordered a new aluminum reservoir with the fuel cell style cap. When it comes in I will install then post my results.

Is there any special fluid that I need to use or is it just antifreeze?

Appreciate all the help

nothing special, just regular old coolant as far as i know

I used distilled water with water wetter...

Bad cap? A friend of mine bought a Terminator and I noticed that it had spewed coolant out of the Intercooler Reservoir. He bought a new Ford cap and has had zero issues since.

Yes two seperate tanks . Which one is it coming from

Sorry just saw your other post , for it to b sparing out seems to me like it would have to b getting pressurized though . Jmo though

How do you load an image from your computer?

It was a very small crack in the corner of the tank. I tried to upload a pic but i dont know how..

Either the resivoir, cap, intercooler (brick), or the o-rings that are on the tubes to the brick have bit the dust. A head gasket WOULD NOT make it spew coolant.
