1986 Chevrolet Blazer Overview

The SUV as we know it today was born in the mid-'80s, and one of the first models was the Chevrolet Blazer (introduced in 1983). Based on the Chevy S-10 truck engine and frame, the Blazer was a slightly smaller, more sporty choice for people who liked to go four-wheeling in a vehicle that could carry all their gear inside and didn't want to drive a huge truck like the Suburban.

The 1986 Chevy S-10 Blazer introduced fuel injection to its optional six-cylinder, 125-hp, 2.8-liter engine. The 1.9-liter, 2.0-liter, and 2.2-liter diesel engines were no longer available on the Blazer as of 1986, replaced by a 2.5-liter "Iron Duke" engine. However, a 6.2-liter 8-cylinder diesel engine was now an option. For 1986, the Chevy K5 Blazer also sported some interior changes: a new dashboard and door panels, plus new seat trim on Sport models.

Air-conditioning, power door locks, power windows (including the rear sliding window), and a limited-slip differential were all options on the 1986 Chevy Blazer.

1986 Chevy Blazer owners rave about its capabilities - towing and going through all kinds of terrain. Rust was a problem, however. The Chevy Blazer was a favorite of young men who wanted to jack up or low-riderize their toys.
