Spent a whole Saturday hunting down a coolant leak on a 6.7 Powerstroke
Tbh, I was sure it was just a loose hose clamp on the degas bottle. Ended up being a hairline crack in the EGR cooler outlet pipe, buried under the intake. Took me like 8 hours to find it because I kept pressurizing the system cold, and it only leaked when it was at full operating temp. Anyone got a good method for finding those tiny hot leaks without getting burned?

That EGR cooler pipe is a real pain to get to.

Honestly I used to think dye was a waste of money but that changed real quick after a similar fight. Now I keep a UV light and dye in the truck, just hit it when it's hot and you can see the streak before it even drips. Way less burned knuckles that way.
