Unbolt the cruise control servo (2 bolts on the top, 1 bolt on the fender side, all 10mm), disconnect the wiring plug and move the unit up and out of the way.
Disconnect the overflow tube and remove the coolant reservoir (10mm bolt). It slides towards the engine and then pulls up.
Disconnect the negative battery terminal (10mm bolt)
Remove the inner fender splash guard (plastic clips). Mine was already removed and never put back apparently so I don't have a picture of that.
Remove the front passenger wheel
Jack up the car and place jack stands on both sides
Loosen the lug nuts on the passenger side front wheel
Put the car in neutral and apply the parking brake
Phillips and standard screwdriver
$5.04 (I wasn't able to replace this)
All of the parts I used were ordered from near Dallas, TX. They're cheaper than the local dealers and they ship quickly. I've linked all of the part numbers to the relevant pages on their site. that has all of these parts and more in one spot for changing the timing belt.
The following list contains all of the parts you will need to get in order to complete the job. I actually did not change the crankshaft oil seal because I couldn't get the sprocket off of the crankshaft. It wasn't leaking so I decided not to tempt fate. The Haynes manual says to drill and tap the sprocket and use a special gear puller to get it off if this is the case. I don't think that can be done without removing the engine and that wasn't going to happen. You also have to replace the sprocket that you drilled and tapped.
Disclaimer: Use these directions only as a guide and at your own risk. You're responsible for any damage you do to the vehicle so BE CAREFUL. Your vehicle may in fact have slightly different methods so use common sense if the directions don't match what you see. The demo vehicle being shown is a 1991 Nissan Maxima SE with the VG30E engine.

If there are any parts that can be improved or if you have any suggestions please .
Wherever possible I reference either the Haynes or Chilton's manual pages that cover the same material. Also when a socket is required I try to include the socket size needed. This is actually my second attempt at this. The first time was a few weeks prior and apparently I was off a tooth or something because the timing was not right. So I had to do it all over again which makes for a better tutorial since I knew what I had to do and what was important to take photos of. I also learned to make a mark on the outer edge of the timing belt's white lines so I could see their position after installation (you can see the camshaft marks but the crankshaft mark is hidden once installed).
While I was doing the actual work using that outline I took many photos so that I could create this tutorial for others to use. All of the smaller photos on this page can be clicked on to open the full resolution photo in another window. I highly recommend viewing the high resolution images so you can see more details. In addition to the timing belt change I also changed the three main belts (alternator, AC and power steering), the thermostat, the water pump, the camshaft oil seals, the spark plugs, the plug wires, the rotor and the distributor cap. It's generally a good idea to do all of these together, especially the water pump and oil seals since you have to do a good bit of labor in order to get the engine torn down to that point.
Recently I noticed that my 1991 Nissan Maxima, with the VG30E engine, was due for a timing belt change. Nissan recommends this every 60,000 miles but both times I've had it done at around 70,000 miles. The first time I had it done at the dealer which cost me $480 with parts and labor. This time I called around and it was going to cost me $700. That was money I'd rather spend on my car audio habit so I decided to see if I couldn't do it myself. I had always considered a timing belt change one of the most challenging maintenance procedures but had never really looked into how to do it. But I had three resources, a Haynes manual, a Chilton's manual and the Internet. I thought between those I could probably figure it out. What I found out was that there wasn't one really good resource available. So I took notes from all the sources and I was able to create an outline of what I needed to do.
