Rocketman3 Posted September 5, 2022 Share Posted September 5, 2022 Hello everyone, I am thinking I need a new radiator on my rig. I have a 2000 dynasty with 103,000 miles. It runs (cools) just fine when the outside temps are below 80 degrees. However, if the temps are higher and we are climbing hills, I watch the temps on my silver leaf rise to over 210+ and the “chirping” noise starts and the “high water temp” lights up. It has been happening more and more often. When I first got the rig - it never happened- now I watch the heat carefully- downshift early, etc to keep the heat levels down . I have sprayed the radiator out the best I can several times - doesn’t seem to help…. I just figure after 22 years the cooling channels are no longer as efficient. I will be in Oregon soon, so I called Source Engineering, they wanted to verify the radiator number on the build sheet is the actual one that was installed before they order it. They said there is a tag on the radiator. Does anyone know where to find the tag and what it looks like? Should I also have the CAC replaced at the same time, what about the transmission cooler?
