    My wife’s 13 PIP 205k miles, felt like I should do some serious preventative maintenance. Removed,cleaned, and reinstalled. It was not as difficult as originally thought. I can feel a difference in power and response. Other maintenance performed.
    1. Drain and refill radiator and inverter.
    2. Replaced water pump and t-stat.
    3.Drain and refill transmission fluid. 4.Replced front brake pads and turned rotors.
    5. Oil and filter change.

    Yeah auto-exposure makes it a black hole in the pic, hard to tell. With a phone camera, tap the black hole, should brighten it up.

    Well, I must say I was pleasantly surprised the cooler was not that plugged. About 157k of HV miles, I would say 50%. It cleaned up pretty easily. I have seen plugged solid coolers. I thinking mostly highway driving is the reason for the condition.

    No Sir. I was actually concerned by it. Tires, oil changes, 12v battery, and gas.

    i wonder if that makes a case for higher miles being better for the egr?

    i have 20k, and am afraid to look at it
