GM (GEO) part numbers for certain critical parts.  
I see GM selling these parts now, after a "DARK AGE" (2007 cost cutting...)
Like Suzuki the online photos and graphics of the car parts are missing.  (in many cases and on all 16v engines)
They (GM) have the parts, but fail to show them in the pages.
So you must know the numbers and then type them in the search box to find them. (some still work, see blue numbers below)
GM lists 4 cars, under Tracker, Base and LSI, but totally skips the KV , 4door, with 16valve engine. (but has the parts, what a mess there)
Do not mix G16A and B parts (sure the bare block) They are different engines. VIN U and VIN 6 engine codes ! Diffr, heads, pistons, etc.
Note how GM changes some 960 numbers to 911xxxxx,  just for funs and giggles, making most GM old parts books, and Fiche , useless, Thanks GM !
Then does that  and makes the web lookup near useless,  now that was a class act , GM.
The online experience ,when a RED ID number is missing in the list that means discontinued, (cute huh?)
Some show, "not shown" but are stocked, and listed like engine mounts.
Some GM parts are 1/2 the price of Suzuki, so,  get motivated?
The few parts shown, do have the real part number stated. (kudos')
GM horror 2,  I see MPI parts there,  and is not indexed. (a 16v throttle body is there)
GM sensor search works with $300 cheaper MAF sensor.
89 to 98 years.


 See GM's unique glove box door RPO codes and markets

They do stock the Left and right headlight  shells,  Unique to this car.

Use this list at your own risk; it is not  official.  The dealer always has current information.  This is a snap shot only, from my 1998 GM micro fiche. GM can change numbers and has in the past !
8V means 8 valves, 16v means..... sure...  Many number below have been substituted by GM or are obsolete.

   varies by FED or California.  not sure what these parts fit, ask GM.  there are 2, 16v manifolds, CAL and FED.
Comments:
Warning all  Calif cars have unique parts,  Exhaust system end to end and manfolds and smog parts and even valves.
EGR and other parts,  Be sure to look at under hood sticker (look upward) on your car to see if  it has EPA sticker "for usage in California" stated. Then tell GM that fact. or you will get the wrong smog  related parts.

Below is the GM 8v valve G16A image live. Some parts are stocked, 16v (VIN 6) image , is missing, at GM.

The old parts list, base engine missing, but has partial engine related parts, Like air induction  piping,exhaust ,Ignition Emission,cooling and A/C parts, oil pan, timing belt cover. sans belt.
(hint, Ignore Japan numbers, use CAMI, which is maked Canada Built that means CAMI made.)  With the link to the left and the online below , all parts in the engine can be looked up, if missin they are NIS (not in stock)"aka. discontinued"



rev5 ,  1-25-2010   (12/2014 new links) My one and only GM page.  Good for one thing, getting parts way cheaper than any Suzuki source. (USA)  or N.I.S. at Suzuki.
