even straighten the driveline. Good luck.........Steve
I only moved it a few inches, so that I didn't have to extend the wiring. The new location gets more air flow and is further away from the radiator. The whole job took me about 20 minutes.
Sorry I don't have pictures... I'll try to explain as clearly as possible.
There are two sensors just in front of the radiator. Top one for A/c and lower one (with white band on harness) for Temp display. To confirm, the lower one should have green/red wire NOT green/white. There is enough slack to move the display sensor and leave the other one alone. However if you move both, you may have even more slack to move them.
First I checked the sensor in a cup of tepid water to confirm accuracy of the actual equipment. My sensor was dead-on. In 77F water the resistance of the sensor was 2.18 ohms.
Just below the sensors is a threaded bolt hole. I borrowed a bolt from my front license plate bracket (since I do not use a front plate) and secured an 8 in piece of soft steel strap that had holes in each end. The strap points up and to the right (about 45 deg)and bend forward (towards the grill). I adjusted the bracket until it was level with the first grill opening near the Nissan emblem. I removed the strap and enlarged the pre-drilled hole in the sensor end to fit the square fitting on the sensor and then painted the metal black.
I installed the bracket and snapped the sensor into the square hole. Then I adjusted the bracket so that the sensor just peaks out the grill opening. Now it get air flow when I move!
I have observed that the sensor has a lot of plastic mass, so it changes temp slowly. Plus the algorithm that Nissan programed slows the change in certain conditions (see earlier posts). Overall I am quite pleased with the new location.
For second generation, I may consider a permanent bracket that holds both sensors. I'm sure the a/c uses the outside temp for something... I'll keep you posted.
In all three cases the vehicle did not respond to the brakes and just kept rolling as if on ice, though the surface was pretty dry. The first 2 times was in 2WD, the last time in AUTO.
Called the dealership, but they gave me some BS about anti-lock brakes. But I've driven cars with anilock brakes before and never had such problem.
I also had a service technician at the Gaithersburg Nissan take it for a test drive but the problem did not show up.
I wonder if anyone else has experienced a similar problem or has an idea on what might cause this.
This is pretty unsettling when you have to worry about whether or not the brand new vehicle is going to stop at the light, or at 70 MPH on the highway.
Any comment or insight are appreciated.
After bleeding the brakes,adjusting them about five times and the Nissan service manual said to "burn" the brakes in about 10 times (I did it 5 times) and 5500mi latter they are almost exceptable. If you want I can e-mail you more info if you want to do it your self, several in this group have gone through this procedure.
Check the NHTSA on 2001 PF about brakes. Please include your problem if you like so Nissan gets the message and upgrades their brake system. Hope this helps.
Meca2, where in the Service Manual does it talk about burning in the brakes? I'd like to read that section. Thanks!
--Howie
Thanks
Thanks for that reference. I hadn't seen that before!
What exactly is this "burnishing procedure" supposed to accomplish? I mean, how does it make the brakes less squishy?
--Howie
P.S. I got the Nissan Grille Guard, and it looks great! I'll post photos soon.
Any ideas on the best approach to convince service that this should be covered by the warranty?
Does anyone remember someone else with similar problem from postings last Fall?
Question: I have been using 2WD on dry pavement per card in the visor; is it OK to leave in AUTO all the time? Seems like all the 4 wheel indicators light up all the time in AUTO.
Agree with using Octane 91 for the PF because of the compression ratio.

The AWD only activates when the speed sensors detects the rear wheels slipping. Also I
do belive there is a pump in the transfer case is activated and might have a slight
decrease in fuel milage. The service manual shows two pumps-machanical and
electric- that runs at slow speeds and when the vehicle is stopped.
Howie-Brake burnising. Might be to seat the pads or shoes. 100% contact between
the pads and rotors or with mine 100% contact between rear shoes and drums.
At 6500mi. I will rotate the tires and might remove a rear drum to look at the shoes
to check contact area. When the wheel is removed the drum should come off the easy.??

He said that this would have been covered under the 12/12,000 bumper-to-bumper warranty, but not after, eventhough I have the extended 5/75,000 warranty.
This exhaust prpblems supposed to end with 96+ models but I've read that a few with newer models experienced it as well. Check yours.
I'm taking a 1,600 miles trip in Mid June and wonder if I should take my 99 SE or the 01 Accord...with gas costs about $2/gl, it's a tough choice.
Get it done asap as the crack will spread.
Thanks
Oops. Gotta run to a meeting. Let me know about the year and I'll type more later.
Stupidly dropped my glass coverage a few months ago to shave a bit off my hefty premium increase in moving from a Honda to my beloved PF and adding on an old speeding ticket that finally made it through to USAA. Ouch!
Can a crack appear in a 6 month old vehicle's windshield due to the mounting or am I grasping at straws? It does seem to start from the corner with no ding in the glass... About 1/2 inch from the mounting the split goes through the glass parallel to the surface, but most of the 4" length it goes through from inside to outside.
Many posts about service reps BS keeps me looking here for info to be ready for whatever comes my way when I take it in (which I now realize should be soon). I greatly appreciate any info.
Good luck!

emissions. In Oregon from 1975 and newer the car must pass the test. Please look
in your Warranty Information booklet that came with your PF. Look under Federal
emission warrenty. There is federal emission defect and Fed. ems. long term defect.
Depends what state and what year and miles is one your PF. Steve
Please let me know if you have a solution.

After 4 days and going through the TSBs on
shimmies one by one, my '99.5 4x4 Pathfinder
w/Bridgestones and 20,000 miles no longer has a
shimmy at any speed!
Recap (maybe it'll help?): I had a fairly nasty
shimmy that would come and go. It would happen
most of the time, but not all, between 65 and 75
mph, sometimes between 60 and 65, and a few times
between 50 and 60. I drive on the same 45 mile
section of road everyday, so it definitely wasn't
road related because it would happen at different
spots on the road and at different speeds. Because of the intermittent nature and that fact that I have my tires balanced and rotated every 3,000 miles, I was 99% sure that it wasn't a balance problem.
After balancing my tires twice, recalibrating the
balance machine and balancing my tires, and then
using a special attachement and balancing my tires, the service shop could still feel the shimmy. They sent it to another shop to do a "radial velocity" (or something like that) test on the tires and wheels per one of the Nissan Service Bulletins. The place they sent it to indexed (match balanced) the tires, a process that has been mentioned on the board before. They match the heaviest part of the wheel with the lightest part of the tire so that less weight has to be used for the balance. This fixed it! I have driven about 400 miles since I got the Pathy back and I haven't felt the shimmy once!
My Pathy is once again a pleasure to drive on the
highway. Also, if you need service in the Madison, WI, area, Linda at Lancaster Nissan was a pleasure to work with. She actually was looking out for me instead of trying to get out of warranty work. Sorry for the long post. I hope it helps.
I just got the Nissan Service Bulletin I had
mentioned. It's 11 pages and includes and lot of
stuff, so I won't attempt to reproduce it on this
page. I will say that on the flow chart, the first question is, "Is this vehicle equipped with Nissan OEM wheels and tires?" If the answer is no, such as if you have already replaced the tires, the flow chart states, "This Technical Service Bulletin and Nissan Warranty Coverage do not address vibration that can be caused by after market products or modifications." Even though you've replaced your tires already, you might ask your tech to print you off a copy of this NTB.
I remember some folks talking about having their
wheels chromed. The next question in the flow
chart is, "Are the Nissan OEM wheels aftermarket
chrome plated?" If the answer to this question is
yes, you get the same response as the guy that has
already replaced his tires.
Nissan Service Bulletin
Classification: ST99-001
Reference: NTB00-061
Date: July 18, 2000
1999.5-2001 Pathfinder steering and/or body
vibration
Applied Vehicles: 1999.5-2001 Pathfinder (R50)
Service Information
If a 1999.5-2001 Pathfinder exhibits steering
and/or body vibration while driven (without
braking) at speeds between 60 and 70 MPH, the
cause(s) may be:
- Road input (road surface imperfections)
- Out-of-balance front or rear tires/wheels
- Insufficient steering rack sliding force
adjustment
- Tire flat spotting
- Excessive tire Radial Force Variations (RFV)
The last part (RFV) is where they look to index or
match balance your tires and if that still doesn't
work, they replace your tires.
Hope this helps.
Nissan's response so far is that there have been no recalls for such problems, nor is there a familiar dossier. Anyone recognize this problem?

Thanks,
The service manager that I deal with at the Nissan dealership mailed a copy of it to me. She got it from Nissan. It was the document she worked off of to get my vibration fixed under warranty.
Thanks,
The service manager basically told they were not going to fix this and to go away. His comment was that it's within factory tolerence and no worse than any other Pathfinders on the lot. This may all be true, but this does not fix the problem. My take is Nissan knows about this and does not want to absorb the cost of doing the special balancing. It's on a lease, so I guess I'll just learn to live with it, and then dump the vehicle. This was my first and last Nissan. Too bad such a minor problem could not be remedied, but I just don't have the time and patience to deal with it.
a slight vibration from the rear diff sounds about like your vib. I changed the
rear and front diffs to syntitic gear lube (amsoil) and most of the vib went away.
Can you provide more details and possibly a parts list. I'm hoping to upgrade mine in the near future.
Thanks
Jonathan
