I was driving and poof look down the gauge is creeping towards red and anti-freeze vapor is whisking out of the engine compartment. High pressure leak looks like it was coming from dead in the middle of the top of the engine.

Hoses look good. I can PMU and send you the video. The anti freeze vapor was pouring out of the area just in front of the intake manifold but behind the throttlebody. Yes the throttlebody heater plate is intact and not leaking

Please disregard I’m such an idiot. I found a small split in the hose that goes from the expansion tank to the motor. We did a bypass a few years ago from the expansion tank directly to the manifold avoiding the Throttlebody plate. I’m in South Carolina so doesn’t get real cold here
