PM Gasuout...he has the info you are looking for.
Were you able to replace ? Looking to do the same.Looking to receive advice from a person that “has been there done that.” My radiator is leaking coolant and needs to be replaced. The vehicle is a Chevy Kodiak 08 C5500 diesel 6.6L. Was trying to do this myself as a shade tree job but have the following concerns. Was told the whole stack (oil, ac, heat exc) in front of the radiator has to be removed. If I have to disconnect the AC lines then this job is over my head. The overflow / fill tank looks to have a solid band holding the hose to the radiator, thus the question, will I need special (GMC) tools to do this job? Any guidance will be appreciated. Also was looking for a total metal radiator to replace the 15258918 plastic/metal radiator, do you know of one? Thanks
