SOURCE: BAD HARMONIC BALANCER
To remove the harmonic balancer on my 1992 Pathfinder, I needed to loosen the alternator and power steering belts, remove the cooling fan (4 10 mm nuts), remove the radiator (2 10 mm bolts hold it to the frame, remove top and bottom hose [The drain **** is covered by what appears to be a coolant line], as well as the overflow tube to the reservoir. With a 3/4" impact gun and a 27 mm socket, remove the bolt that retains the alt, ps shieves and the harmonic balancer to the crankshaft. With a large 3 jaw puller, remove the harmonic balancer with the pully sheives as an assembly. I do not recommend attempting the removal without the puller.
To put it back on, you will need a large torque wrench for the crankbolt and a small torque wrench for with a crowsfoot for the fan nuts.

It has to be pressed off with a harmonic balancer removing tool similar to this http://cgi.ebay.com/ebaymotors/Parts-Accessories_Automotive-Tools__HARMONIC-BALANCER-DAMPER-PULLEY-PULLER-REMOVER-TOOL_W0QQitemZ260372587534QQddnZPartsQ20Q26Q20AccessoriesQQadiZ2871QQddiZ2811QQadnZAutomotiveQ20ToolsQQcmdZViewItemQQptZMotors_Automotive_Tools?hash=item260372587534&_trksid=p4506.c0.m245&_trkparms=72%3A1171%7C65%3A12%7C39%3A1%7C240%3A1318
You can or may be able to rent one from one of your local parts houses like NAPA or Autozone.

You can try simply wiggling the balancer and see if you get lucky. A few taps with a rubber mallet may convince it to come free. Worst case get the kit. You should not need to remove the radiator. Do make sure that you have the engine blocked so you don't lose your timing mark placement.

There is a nut in the center of the balancer... loosening may require an "impact" or a sharp blow with a hammer to begin to loosen the nut. Once loose, you can use a harmonic balancer puller (rentable at a local rental yard) Since its a very tight fit you'll need the puller to persuade it loose from the crankshaft.... watch your knuckles...
