Coolant everywhere

[SandawgK5]

I heard a rumbling noise when I was getting off the highway just now and when I got home I popped the hood and this is what I found.






I am hoping it is just a bad cap even though that one is only about a year old.

My ECT/EOT was 196/203 and I have not had any other real issues with it since I have owned it. The coolant looks that low because it is parked on a slight up hill. It was right at Min or just below.

Needless to say the research is commencing to determine the extent of the problem. Any advice or tips that may have worked for you guys and gals for diagnosis would be awesome.

Thanks

My truck did the exact same thing the other day minus the rumbling noise. Changed the cap and it still leaks just as bad. do you have any idea what the cause is?

I just took some videos of mine. I really need to get a pressure gauge and see what the coolant pressure is doing. I just went on a test drive and my coolant jumped from 194 to 200 with half throttle on an on ramp. I also have some blueish smoke even when the engine is warm now too.

Also, I checked and did not find any oil or fuel in the coolant, at least not visible amounts.

The rumbling noise was a flash boil condition. If you had been heavy on the pedal and did not run it for about 5-10 minutes before shutting down, the EGR cooler will create this condition, especially with an aggressive tune. However, make sure your cap is working at the correct pressure. This is just another reason to do the EGR delete.

I live in Cali I can't delete. I think I might have an EGR cooler problem even though my oil temps are fine. I need to do the bubble check on the Bullet proof website to see just what though.
