Hello I have posted a thread before about how I got water in the cab when it rains everybody said clean the cowl drains out I did that and cut the old seam seal out siliconed it let it dry and then flex sealed it and it still leaks when I put the water hose on top of the cowl. It looks like it is going in the square hole that is towards the engine on the passenger side of the truck. When the truck is warmed up and I run the water hose on it the water that leaks in is warm it is not antifreeze how can I fix this issue. Thanks
