The S10 was fitted with its Iron Duke 2.5-liter motor starting in the year 1987. This build was originally designed in the Pontiac division of the General Motors company. After years of failed I4 blocks in the light-duty trucks, a decision was made to insert the 2.5 into the Chevrolet S10 truck series. People often prefer this pairing over the late model V6. It is easy using this website to purchase a Chevy S10 2.5L engine.
The Iron Duke motor has an RPO code of LN8. This was one of the final throttle body blocks used by GM during the 1985 to 1989 production years. The first version of the 2.5 that was used inside of the S10 was the 8:2:1 compression block. This was available in the 4-cylinder build apart from the larger 2.8 V6.
Replacement I4 S10 Motors
There is more than one 2.5 motor that was installed inside of the Chevrolet light-duty truck series from 1987 to 2004. The most common editions are the LN8 and the L38 blocks. These are the same units although the late model L38 has a rated 110 horsepower range. The compression is also different at 9:0:1.
GM did end support for its Iron Duke block in the mid 1990s because the Vortec series was more commonly requested. The GMT325 platform was also fitted with the 4.3-liter V6. As production came to a close in 2004 for the S10, auto owners were left without a valid way to purchase complete blocks for their trucks.
Someone who is just now sorting through secondary market retailers might still have difficulty finding the older 2.5-liter editions. The PreownedEngines.com is still supporting the older models as well as the early 1990s TBI builds.
S10 and Sonoma 4-Cylinder Blocks
The Chevy and GMC trucks usually have the same engine variants. In the case of the S10, the Sonoma or S15 truck also used the 2.5-liter builds. These compact truck engines are built for RWD trucks. The front engine design is a mark of quality by General Motors. The S10 and Sonoma are compatible with the 3, 4 and 5-speed gearboxes that were offered in the smaller truck series.
