Here is a handy-dandy table that FINALLY lays to rest exactly what 4-cylinder engine was in which model/year of Suzuki/Geo vehicle!
The following picture is from the Chilton Total Car Care Series (Nichols Publishing) Import Trucks and SUV CD (part #C3050).
Other than an actual Suzuki or GM Factory Service Manual, the Chilton CD is the BEST source of information on Sidekick/Tracker maintenence! You can obtain a copy at most autoparts stores that carry Chilton products or you can order it at Amazon.com and at many better auto parts stores.
