I was wondering if any folks had preemptively added an epoxy fillet around the square edge and what the results may be. It could make the part good for another 100k, or there is a small chance it will just move the stress riser elsewhere. I'm just a simple EE and material properties and stress/fatigue analysis are not my thing. That and not having access to a FEM for the radiator. I'll try to get some of my materials people at work to take a SWAG.Running 18 months on JBWeld plastic epoxy which was rather crudely applied. Did not have leak prior to install but I sanded the plastic and hoped to minimize extension of the stress rider.
Plastic epoxy was rated for well below zero to nearly 400F so good to go.
