- 1983–1986 Single-source
the OHV engine enlarged to 2 liters for 1983; Wikipedia's Cimarron article (infobox and text, which dates the 2.0 L from 1983) and its 122 engine article give it to the Cimarron 1983–1986 (the 122 article also says LQ5 was introduced midway through 1982, but its applications list gives the Cimarron L46 for 1982 only and LQ5 for 1983–1986, and the row follows the applications list); the article names no four-cylinder after 1986, so 1987–1988 are left out
