GM Storm/Spectrum 1985-1993 Repair Guide



See Figures 1, 2 and 3

Naturally, without the proper tools and equipment it is impossible to properly service your vehicle. It would be impossible to catalog each tool that you would need to perform each or any operation in this guide. It would also be unwise for the amateur to rush out and buy an expensive set of tools on the theory that he may need one or more of them at sometime.

The best approach is to proceed slowly, gathering together a good quality set of those tools that are used most frequently. Don't be misled by the low cost of bargain tools. It is far better to spend a little more for better quality. Forged wrenches, 6 or 12-point sockets and fine tooth ratchets are by far preferable than their less expensive counterparts. As any good mechanic can tell you, there are few worse experiences than trying to work on a car with bad tools. Your monetary savings will be far outweighed by frustration and mangled knuckles.

Begin accumulating those tools that are used most frequently; those associated with routine maintenance and tune-up.

In addition to the normal assortment of pliers and screwdrivers, you should have the following tools for routine maintenance jobs:

  1. Metric and SAE wrenches, sockets and combination open end/box end wrenches in sizes from 3mm to 19mm, 1 / 8 in. to 3 / 4 in. and a spark plug socket (13/16 in. or 5 / 8 in. depending on plug type). With Spectrum and Storm vehicles, you will most likely find that Metric tools are usually sufficient or required for your purposes.

If possible, buy various length socket drive extensions. One break in this department is that the metric sockets available in the U.S. will all fit the ratchet handles and extensions you may already have ( 1 / 4 in., 3 / 8 in., and 1 / 2 in. drive).

  1. Jackstands for support.
  3. Oil filter wrench.
  5. Oil filler spout or funnel.
  7. Grease gun for lubrication.
  9. Hydrometer for checking the battery.
  11. A container for draining oil.
  13. Many rags for wiping up the inevitable mess.

In addition to the above items there are several other tools that are not absolutely necessary, but handy to have around. These include oil dry, a transmission funnel and the usual supply of lubricants, antifreeze and fluids, although these can be purchased as needed. This is a basic list for routine maintenance, but only your personal needs and desire can accurately determine your list of tools.

The second list of tools is for tune-ups. While the tools involved here are slightly more sophisticated, they need not be outrageously expensive. There are several inexpensive tachometers on the market that are every bit as good for the average mechanic as a $100.00 professional model. Just be sure that the meter goes to at least 1500 rpm on the scale and that it can be used on 4, 6, or 8 cylinder engines. A basic list of tune-up equipment could include:

  1. Tachometer.
  3. Spark plug wrench.
  5. Wire spark plug gauge/adjusting tools.

In addition to these basic tune-up tools there are several other tools and gauges you may find useful. These include:

  1. A compression gauge. The screw in type is slower to use but it eliminates the possibility of a faulty reading due to escaping pressure.
  3. A manifold vacuum gauge.
  5. A 12V test light.
  7. An induction meter. This is used for determining whether or not there is current in a wire. These are handy for use if a wire is broken somewhere in a wiring harness.

As a final note, you will probably find a torque wrench necessary for all but the most basic work. The beam type models are perfectly adequate although the newer click types are more precise.
