Pin 9 - Gray

The function of each pin will depend on what signaling standard you are using. I am also unsure if these colors are ubiquitous, or if it just a standard that is typically followed.

Keep in mind this follow a very similar color-numbering system to resistors. Just remember that resistor color-numbering starts at 0, while pinouts start with 1. You will need to memorize that black and brown come first and gray comes last, the others follow the old ROYGBV of colors. Red, Orange, Yellow, Green, Blue, Violet. Indigo is usually skipped because it is too hard to make an indigo that won't be confused as either blue or purple. It's kinda like removing the letter "I" from alphanumeric tagging systems so as to not confuse it with the numeral "1." I used this to remember how to "count" with colors in college, and I use it regularly as an EE.

To find information on various pinout standards that use the DB-9 or DSUB-9 connectors you are left to your own searching via google or wikipedia for best results.

Good luck!

You need to run at least 500 watts from a real amp to push the speakers to potential without overheating. I am running a 1x1000watt monoblock kicker amp at both of them and it is all I ever wanted and it will handicap anybody within 100ft of the car.

If your Jeep needs a cooling system flush, this is a great time to do that. It's helpful to install a flush-and-fill kit and to get a container of radiator flush concentrate. Let the concentrate circulate in the engine for the length of time specified and then let the engine cool. 10-minute concentrate seems to work pretty well.

Rather than drain the old coolant through the draincock as may be specified on the concentrate instructions, you can get good access to the lower radiator hose by removing the air filter housing which is located on same side as the power steering pump. Unclip the top of the air filter cover and move to the side. Remove the air filter and then remove the 3 bolts holding the housing to the engine compartment.

With a catch pan in place (flat, 2- or 3-gallon), loosen the clamp on the radiator side of the lower radiator hose. Let the old coolant drain into catch pan. Transfer the old coolant into sealable containers until you can take them to a recycling or disposal facility.

Using the flush-and-fill kit, flush the engine cooling block (cool engine only!) until water is clear coming out the lower radiator hose.

Same can be done with the radiator. Pour clean water into the top of radiator and let it run out the port for the lower radiator hose. You'll get a more complete flush of the entire radiator if you temporarily plug the port with a hand or rag and then release once the radiator is filled.

If your serpentine belt has cracks on the grooved side or if your radiator or heater hoses are getting old, this is a good time to replace them. Some Jeeps also seem to "eat up" thermostats pretty quickly. Get a replacement 195 degree thermostat and gasket if you want.

Now for the water pump replacement.

Loosen and remove the serpentine belt. Remove the power steering pump. There are 3 bolts that attach to a bracket that is attached to the engine block. Plus 2 bolts that secure the PS pump to the water pump. The PS pump will still be attached to the car by the hoses but it can now be moved out of the way. USe a bungy cord or something to keep it away from the work area. Now there are 4 bolts that attach the water pump to the engine. 3 of the bolts will be visible. The fourth is below the water pump. You also need to remove the pulley from the water pump. It's attached with 4 bolts. Keep this handy as you need to install the pulley on the new water pump.

Loosening the bolts on the water pump pulley can be tricky since the pulley will spin and there is nothing really to grab onto. One thing that helps is to use a long narrow bar put diagonally between 2 of the pulley bolts while you loosen another. A long (and strong) Allen wrench works well.

Lever the Allen wrench or similar against 2 bolts and loosen the bolt closest to you. Take care that the bar does not slip (and your knuckles get banged up)! Leave this bolt in its hole after just loosening it. Rotate the pulley to next bolt and repeat. Once all are loosened you can hold the pulley by hand and remove the 4 loosened bolts

There are 2 hoses attached to the water pump. The heater hose and the bottom radiator hose. Remove the hoses and you should now be able to remove the water pump. You may also have to remove the electric fan and fan shroud prior to removing the water pump. There was no electric fan on the 1996 Cherokee that this novice just replaced so it was not an issue. After removing the old water pump unscrew the pipe for the heater hose or buy a new one. Use some teflon tape and attach this pipe to the new water pump.

Be sure to install the heater hose pipe to the new water pump so it will be lined up with the heater hose when the pump is installed. You won't be able to rotate the heater hose pipe after the pump is intalled.

You also need some RTV silicon sealer for the water pump gasket. Put a thin layer on both sides of the gasket. Clean the area where the water pump attached to the engine and then carefully put the new water pump in place. Now secure the water pump to the engine and then put the pulley back on. Reverse the above steps and replace the PS pump. BTW to loosen the serpentine belt first loosen the bolt that holds the pulley located directly below the PS pump. Then back off on the tension bolt which is located on the bracket that secures the PS pump at the top of the bracket off to the left side of the PS pump. Fill with coolant and you should be good to go. This procedure was just performed on this novice mechanics own 1996 Cherokee yesterday (now successfully done on 2 Jeeps). So far so good. Good Luck. BTW you will need 13mm, 14mm and 15mm sockets and wrenches to remove and replace all the bolts mentioned.

This means you need to get your CD Changer repaired. The in dash CD changers Nissan put into the Pathfinder is notorious for this issue. From what I recall, on the OE changer (by Clarion, I think) there is a plastic screw inside that controls the changing of the discs that breaks/wears out. If you take it to your local Clarion service place, they should know what to do with it.

When I brought mine in, the guy knew the vehicle it came from without hesitation. I think it cost about US$150 to fix.

They have to send it to California, so it took about 3 weeks to get back to me, but it works fine now.

New probably 40-60 psi 20 year old ???

The 2004 Nissan Pathfinder has a 3.5 L base engine size.

There should be an emergency release cord inside behind the paneling next to the gas door.

this happend to mejust pry it open with a screwdriver watch the paint and try replacing the spring go to Nissan cost me $1

blower motor has a short. replace blower motor

I had the same problem with my 95 pathfinder, fix by checking all of the connections on the wiring harness that run by the rear bumper to the fuel pump on top of the gas tank. Mine were salty and dirty.

it will require some cutting but 24's will fit a 745. The cutting is mainly inside the wheel base so its not noticeable.

a failing clutch will slip,in 4th or 5th if you floor it the engine will speed up without the car going faster

check for blown fuses

1.

Disconnect the negative battery cable. 2.

Properly drain the cooling system into an approved container. 3.

Remove all accessory drive belts or the serpentine belt. 4.

Remove the alternator and bracket. 5.

Unscrew the water pump pulley mounting bolts and then pull off the pulley. 6.

Unfasten the mounting bolts, then remove the water pump. 7.

Using a putty knife, clean the gasket mounting surfaces. To install:

8.

Place a 1/8 in. (3mm) wide bead of RTV sealant on the water pump sealing surface or install a new gasket, on models so equipped. Install the pump and tighten the retaining bolts to 18 ft. lbs. (25 Nm). 9.

Install the water pump pulley, then tighten the mounting bolts to 22 ft. lbs. (30 Nm). 10.

Install the alternator and bracket. 11.

Install the drive belts or serpentine belt, as applicable. 12.

Fill the cooling system to the proper level. 13.

Connect the negative battery cable, then start the engine and check for leaks.

Ours was simple... as in 95% of ALL car problems. Usually just hard to determine what 'exactly' is wrong in the first place. New plugs made ours run 1000% better. Wires didn't help, but if you're replacing plugs, especially 'old' plugs, do the wires too. Check and clean the cap and rotor if any. The final problem was to get a new Cat. Converter and weld it on. (Light was coming on intermittently) Dokter Denney

THERE IS NO DIP STICK, THE TRANSMISSION IS A SEALED UNIT.

Your Converter Has Internal Melt-down. It Must Be Replaced.Your Car Could Catch On Fire.

There should be punched marks on the cam sprockets which need to be lined up with factory punched marks on the rear timing belt cover, immediately behind and just above the sprocket. Line those 2 gears up and bring crank shaft damper to 0 degrees top dead center according to first mark on dampers, left side as you face the motor check to see if your distributor rotor is facing the number one terminal if not complete full rotation because motor is on exhaust stroke.

Similar problem w/2000 Pathfinder; I get "error 1" & it won't play the cds. Did you ever learn how to interpret the codes?

Your CD player is really a Claroin CD player I had the same problems , I removed it from the radio combination and took it to a Clarion service store and they repaired it. I called Nissan and Bose and they couldn't help me.

There could be a few problems....wiring issue, the gauge in the dash has gone bad, or the sensor for the fuel float is bad, id check wiring and the gauge first because sending units are expensive and can be a pain to change

Loose or corroded battery cable?
Blown fusable link?

In 4HI mode you have permanent traction on both axes front and rear (50-50)

In 4LO mode, as in 4HI, but in addiction you've a shorter transmission ratio for your drive, it let you to climb steeper slopes ;-)

1)raise the car and remove the tire.2)remove the brake caliper.3)use a screwdriver to remove the hub dust cover.4)remove the cotter pin,adjusting cap,wheel bearing nut and washer.remove the outer wheel bearing.5)remove the hub and rotor assembly.
