any coolant contamination, however minimized, will likely result in some kind of transmission issue in the futurethetrance wrote:for those of us who havent done the radiator bypass yet, has anyone considered putting a lower PSI radiator cap, say 13psi, to reduce the amount of coolant getting into the transmission in CASE it fails?
so if we reduce the pressure difference, that would technically reduce coolant getting into your transmission, correct?
Of course if you lower the pressure, you also lower the boiling point of the coolant. One pound of pressure equals 3 degrees F. I think the best method is either replace the radiator or do the bypass.thetrance wrote:for those of us who havent done the radiator bypass yet, has anyone considered putting a lower PSI radiator cap, say 13psi, to reduce the amount of coolant getting into the transmission in CASE it fails?
not 100% sure what the pressure in the tranny line normally is, but i assume at idle its around 20ish psi? so if we reduce the pressure difference, that would technically reduce coolant getting into your transmission, correct?
any thoughts?
Thanks!
The radiators of this vintage were very poorly manufactured, to put it mildly. If you want to gamble and lose it all ($5-7,000. Very expensive & complicated transmission few are qualified to rebuild.) after all have been saying to you, that is your choice. It is just that so many of us on this forum (as well as the Xterra & Frontier) know that this has been a huge problem for Nissan & very, very few escape its grasp. Maybe you like to live on the edge, but after hearing the horror stories, I for one couldn’t stand the high anxiety this issue was causing me, so had a local shop replace the radiator for ~$350. Either that or spend thousands on the alternative. The advice we are giving is: “Trust us. Don’t put it off”.thetrance wrote:I got this suv used with 156k miles on it. original radiator.. hoping that it would've leaked by now if it was a faulty unit...
and how do you know that you are not going to lose your transmission in the long run due to the higher temperatures? there are several posts in other forums showing temps hitting 200+ once you bypass the radiator. I am looking at the big picture here.CPLTECH wrote:The radiators of this vintage were very poorly manufactured, to put it mildly. If you want to gamble and lose it all ($5-7,000.
