Chevy 3.5 Specsby Justin Cupler
Chevy introduced two new engines in 2004, the 3.5-liter V-6 and 3.5-liter I-5. These two engines were the replacements for several older Chevy engines: the 3.1-liter V-6, 3.4-liter V-6 and 4.3-liter V-6. The V-6 was used in several cars between 2004 and 2011: the Malibu, Malibu Maxx, Monte Carlo and Impala. The I-5 version was used in the Colorado in 2004 and 2005.
The Malibu and Malibu Maxx were sold with the same version of the 3.5-liter engine. This engine was used in these cars from 2004 through 2007. This engine had a bore --- cylinder width --- of 3.7 inches and a stroke --- piston travel inside the cylinder --- of 3.31 inches in 2004, and 3.3 inches from 2005 through 2007. This engine produced 200 horsepower (hp) at 5,400 rpm in 2004 and 2005; 201 hp at 5,600 rpm in 2006; and 217 hp at 5,800 rpm in 2007. The torque was rated at 220 ft.-lb. at 3,200 rpm in 2004 and 2005; 221 ft.-lb. at 3,200 rpm in 2006; and 217 ft.-lb. at 4,000 rpm in 2007.
The 3.5-liter V-6 was also placed in the Chevrolet Monte Carlo during the last two years of its production life --- 2006 and 2007. This version of the 3.5-liter engine had a bore of 3.9 inches and a stroke of 2.99 inches in 2006, and 3 inches in 2008. This engine produced 211 hp at 5,800 rpm and 214 ft.-lb. of torque at 4,000 rpm.
The Chevy Impala had a 3.5-liter V-6 installed as the standard engine from 2004 through 2011. This engine has a bore of 3.9 inches and a stroke of 2.99 inches in 2007, and 3 inches from 2008 through 2011. This engine produces 211 hp at 5,800 rpm in every year. The torque rating is 214 ft.-lb. at 4,000 rpm from 2007 through 2009, and 216 ft.-lb. at 4,000 rpm in 2010 and 2011.
The 2004 and 2005 Chevy Colorado's 3.5-liter engine is completely different than the others. Instead of being a V-6, this engine is an inline five-cylinder (I-5). This engine has a bore of 3.66 inches and a 4-inch stroke. The 3.5-liter I-5 produces 220 hp at 5,600 rpm and 225 ft.-lb. of torque at 2,800 rpm. This engine was replaced in 2006 by the 3.7-liter inline five-cylinder engine.
