i'll try to keep the story short:
we bought our 07 black armada back in january. since the ground has been covered with snow the past several months, we never saw any leaks, but now that its melted, our driveway is covered with oil stains. i crawled under the Mada and found it covered in what appeared to be either Power Steering fluid or Transmission fluid. i did a thorough job cleaning it up and took it for a spin to get it to leak again and find the leak. came back, covered in the fluid again. i got on here and started going thru other peoples threads on similar issues and began my search to find the ever so popular trans cooler leak. yup. i had the one. but my fluid was leaking from higher up than that, so i kept looking. i have located the common trans cooler leak, a power steering cooler tube leak, and a seperate trans cooler leak that is oozing coolant. here are a few pics with some decriptions in case anyone else has similar problems in the future and needs some guidance.
the car was purchased certified pre-owned from Russ Darrow Nissan in Milwaukee, WI on Brown Deer Road. they are telling me it won't be covered because there is not a warranty on the vehicle. Ironically, I am still waiting for my OLD warranty to be refunded to me from my last Armada because the previous dealer says they dont have my adress (odd, since i mailed them a letter from my current address and put my address and phone number on the letter) so now I am stuck in between warranties. both of these will be EASY fixes, but its the principle of the matter, i shouldnt HAVE to fix it, they should. anyway, on to the pics.
here is where i located the comon leak many others have. coming from the tiny hose, red fluid, lightweight. when the vehicle is running, this hose would slide back to the bead in the tube from the pressure. until i get a new clamp, i slid the current clamp back about an inch to keep the rubber line from sliding back and it also slowed down the leak DRAMATICALLY from having new rubber to contact. simple fix: new clamp just like everyone says.
still leaking fluid, i traced it up as high as i cold and this was the highest spot the red fluid was coming from. the power steering cooler lines that are mounted to the frame rail. adjusted the clamps quickly, problem did not go away.
while i was peering in thru the grille, i also located this leak coming from the passenger side of the trans cooler. it is obviously the coolant, but the wierd thing about it is that it is very thick, almost as if it has a leak-stop agent in it, which tells me the dealer KNEW about the problem and rather than fixing it, just threw in a bottle of rad-leak stop and called it a day. thanks jerks.
heres another angle of the trans cooler leak.
ok, time to go to work, so i removed the bumper, cleaned her up really good. took her for a spin and identified this to be the exact spot the PS fluid leak is coming from. note that before the picture, i dried it off a little bit. the fluid was leaking from under the frame bracket that holds the lines down.
aaaaand a little better pic of the trans cooler leak.
i slid back the bracket on the PS cooler lines and found this pinhole knick in the left line. it is a nearly perfectly shaped knick, as if the bracket was too tight and cut the line.
ironically, the leak was not coming from the previous pinhole. it was ACTUALLY coming from right here. the top of the right side line has been completely worn down in one spot by the bracket. it leaks with the vehicle running at a relatively rapid rate. with the vehicle not running, it kind of just oozes.
i called the dealership about the specific leaks and metioned the TSBs on the PS leaks and TRans cooler leaks. problem is they are about an hour drive away from me. Both leaks will be getting a dab of JB weld to stop the leak so I can make it down to the dealership. if they have a problem with my trailer trash fix, they can suck a fat one, because i have a sneaking suspicion they knew about both leaks and just tried to cover it up.
