Got a call back from the radiator shop today and the tubes were clogged to where it was only performing at around 25% cooling capacity. They flushed it out but the scale was so severe there were several holes that appeared. When one was fixed two more would pop up.
I was quoted 2300 for a new radiator core but I was hoping someone on here might have another avenue for me to look into.
Update on my issue:
With the help of a friend who spent a few years working as a mechanic at freighter we narrowed down the problem to be the emergency dash valve. I ordered a new one and installed it today. Lo and behold I was able to release the parking brakes AND have my parking brake light turn off. I also learned that I need another new brake canister now that I’m getting air to it.
Thanks everyone for all the input. Even the remarks on the questionable welds to the frame😂. If yall really wanna rag on my truck I can post some more pictures.
next on my list is to get the wiring for the tail lights and trailer lights in working order.
