Very interesting. Ever since I bought my truck I've always noticed that the Intercooler pump will just kick on. Truck's been sitting for 4 hours without the key inserted and I'll come outside to smoke a cig and hear the pump kick on. It will run for about 2 minutes and shut off. I myself, not knowing shit about the system, always thought it a bit strange but hey maybe its supposed to do that. My friend who's helping me with all of this shit is now telling me he noticed it as well and it should not be doing that. I wonder if its jacked up and has never operated correctly.
I've had the same thing happen with my truck regularly over the 5 years that I have owned it. Mentioned the issue to multiple mechanics who seems to think it was a non issue and since I could never replicate the "issue" for them it didn't seem like something they were keen to troubleshoot.
Anyone else have some insight on why it's happening and whether I need to be looking further into it.
