Mobil 1 75W-90 can be obtained for cheap if you order online from Advance Auto Parts and use discount codes (Google for them). You can get 5 quarts for about $35. No LSD additive is required with M1.

Check fuses listed on page EL-121 of the factory service manual for your specific audio system; fuse numbers are depicted on the third page of the foldout section of the FSM. Can somebody fix the damn forum software to actually parse links correctly without having to paste as plain text first?

Yes, unbeatable price for M1. How long will you be running the oil? Unless you run it 6k or longer there is no benefit; conventional oil will protect just as well. Not saying there's anything wrong with M1 especially for the great price, just something to think about.

Seems like a recurring issue as of late and I don't mean to sound like a broken record but, engine coolant temperature sensor? Welcome to NPORA!

It's not hate, it's just not specified for out vehicles, plus VQ engines tend to shear oil and lower its operational viscosity.

5W-20 is not suitable for our engines. Exchange that jug for a 5W-30 jug.

http://www.nicoclub.com/FSM/Pathfinder/2000_Pathfinder/el.pdf'>Page EL-5 of the factory service manual should help you out.

What is the color and smell of the fluid? Does it smell burnt?

Engine coolant temperature sensor? Its position is described on http://www.nicoclub.com/FSM/Pathfinder/1995_Pathfinder/ec.pdf'>page EC-12 of the factory service manual. I can't find any reference resistance values, so maybe just replace the part and see if it improves.

It takes all of five minutes to remove and replace the door panel, and the button is easily accessible after removal. There is even a pictorial guide on NICO http://forums.nicoclub.com/how-to-remove-door-trim-on-1999-qx4-t445467.html'>here. Maybe that would change his mind?

LEDs draw next to no current. You may have blown a fuse if you installed the LED bulb backwards since they are polarized.

Room lamp fuse behind coin tray?

The only ones I have heard of is Bosch and Brembo. Out of those choices, Bosch or Brembo are good picks.

Do you mean VQ35DE? A VG35DE doesn't exist as far as I know. The VQ35DE is a very tight fit in an R50 engine bay as it is, I don't think there will be enough room in a WD21 for it.

On R50s, both front and rear brakes automatically self adjust every time the brake pedal is pressed.

A Magnefine inline filter is inexpensive and would be a good idea. Place it on the cooler return line. You'll need a 3/8" one.

It is very easy to do a fluid exchange in your driveway, paying anything to have it done is a waste of money in my opinion. Disconnect the return line and start the engine, when the fluid starts sputtering out of the return line the trans is more or less empty.

The trans won't suck up fluid through the cooler input line. Just disconnect the passenger side cooler line to drain the trans.

I think on 4WD Pathfinders only the front driveshaft has a grease fitting. Otherwise, the rear driveshaft has a grease fitting towards the front end of the vehicle. What specific gear oil did you use? Is your rear diff an LSD?

I also run Castrol IMV in my Pathfinder.

Oops, didn't check the next page on my phone. Facepalm.

1996 - 2000 Pathfinders in the US have a VG33E. 2001 - 2004 Pathfinders in the US have the VQ35DE.

If you have the VQ35DE and you also need to replace the MAF sensor itself, the $89 Maxima MAF will work.

Engine oil additives are worthless. I would avoid using any at all. Which fuel system cleaner did he purchase? Not all are as equally effective.

Any fluid claiming to meet Dexron III is suitable. Dexron III is no longer a current specification and is not a licensed fluid, so the fluid is not guaranteed to meet or exceed DexIII specs. But any name brand or even store brand fluid should be fine, it's just the unknown brands sold in gas stations you'd have to worry about. There is also no superceding Nissan fluid for Matic D; you can't use J (obsolete) or S (Dex-VI like?) in its place. M1 ATF will work fine. Perhaps the older DexIII based formula listing Matic D on the bottle would be 'better', but it should not make much of a difference.
