My truck spits coolant only when I mash on the gas. It cannot be seen on the ground but it shows all over my front driveshaft and ladder bar on my driver side. Does anyone have any ideas? Truck has had 3 radiators upper and lower hoses replaced as well as egr valve. I recently installed sct dpf delete but problem was apparent way before the install. Also, if I need to take my truck to dealer do I need to put my dpf filter back on? Or can I just set truck to stock without dpf in place? Any help is much appreciated.
