edubR51 Posted February 19, 2019 Share Posted February 19, 2019 Hello everyone! I just purchased a 2008 R51 4x4 S. It has 90K miles and runs great. Since I bought it I have been reading about the common transmission problems with this generation Pathy, so I am aware of the option to bypass the radiator cooler. I did purchase the truck with a full warranty. That being said, I am a little reluctant to bypass the radiator cooler and just run the factory external cooler because I don't want to void the warranty the truck came with. So, my question is... Is there an aftermarket radiator I can switch the factory one with to remedy future failure from the factory radiator leaking? Or do I just let it go and if it fails just repair it under warranty, because it would definitely be covered. I have checked the tranny fluid and coolant often, and so far have not found any signs of the 2 fluids mixing. The truck runs awesome, shifts great, and has plenty of power, so I don't really want to let it fail. I just want to get everyone else's input. Thanks in advance, and i'll have pics up as soon as I can take some nice ones out in the dirt or snow. Link to comment Share on other sites More sharing options...
Slartibartfast Posted February 21, 2019 Share Posted February 21, 2019 AFAIK the strawberry milkshake of death problem was only an issue with the original radiators, so a decent aftermarket rad would probably be alright. Having seen what happens when the stock cooler fails, I'd want to get that junk out of there. 2 Link to comment Share on other sites More sharing options...
pocoloco27 Posted March 21, 2019 Share Posted March 21, 2019 Hi all, I'm also a new owner of a 2010 R51 4x4 and enjoying it thus far. I've been reading about the SMOD issue and apparently I have the early 2010 rad in mine, which may be at risk of SMOD, but not to the extent that the earlier trucks were. Should I just change the rad? Which aftermarket options are good? Option 2 is I could bypass it (if not already done). I do plan on towing with this truck, so adding a second external cooler might be a good plan. If so, what brand/size of second external cooler? Thanks, Chris Gatineau, Quebec, Canada Link to comment Share on other sites More sharing options...
