It will "solve" the issue for however long it takes the new radiator to develop a leak again. If it does leak again, you won't know until your tranny starts to act up. You may or may not have the issue, and you won't know until it's too late. Most do it as a preventative maint. so they don't have to worry about it.gilliam433 wrote:Hey guys, normally I would do research and read through this entire thread, but I wanted to just go ahead and ask something if thats cool.
I took my Pathfinder into the shop today to get the Fuel Sending Unit replaced under warranty. Got a call from the dealer saying they were going to replace the FSU and also found a leak in the radiator and were going to replace that under warranty as well.
I didnt realize any noticeable leak in the radiator, obviously, but will this replacement of the radiator solve this bypassing issue or will that still be something I need to worry about.
Thanks!

i don't know whether that improvement is by a design change or an improvement in the manufacturing process
none of us may ever know
with an internal transmission cooler there is always going to be the potential for this kind of problem
mine are both by-passed, and will remain that way
i, for one, will not take the chance
both coolers are currently in your loop, one external, and one internal (in the bottom of the radiator)gilliam433 wrote:Ive been reading now, and I will more than likely do this Bypass, seems easy enough to do. Basically there is a cooler in the radiator and that is where the hoses are directing the fluids currently. And what we are doing is capping the radiator cooler off (i still have no clue what the radiator does...sorry, havent spent much time under the hood), then taking the hoses and connecting them to a cooler that is already under the hood of my nissan, just not being used at the moment and so you end up with a capped off radiator and a flow between the transmission and this misc. cooler.

the latter one is the one eliminated by the by-pass
Good Thoughts. Thanks!Baedarlboo wrote:Reason most are suspect of even the "new" radiator is because the part number hasn't changed. Usually when a part has been "revised" there's a part number that supersedes the old. The part number for the radiator regardless if it's the original or the new radiator is the same. This same part is also shared with the Frontier owners, who also seem to have the same issues. Read and use your best judgment, nobody here can really tell you if the bypass needs to be done or not.
I'm not eieio, but there is a post on here about a guy who caught the leak in it's early stages. He flushed the trans a few times and has reported no ill effects. Some get lucky, and others get the shaft. If you haven't noticed any odd behaviors, and the coolant did in fact leak in to the trans, flush it a few times and count your blessings.gilliam433 wrote:last question, for now, eieio. Youve been a great help man. When I go get my car from the dealer today, should i ask them if the transmission has gotten contaminated as you suggested earlier today. Would a transmission flush do anything to help that situation?

absolutely ask if there was contamination!gilliam433 wrote:last question, for now, eieio. Youve been a great help man.
