The 2003 Honda Accord 4 cylinder has a timing chain and the 6 cylinder has a fiberglass-reinforced toothed timing belt.
The Honda Accord // is a series of automobiles manufactured by Honda since 1976, best known for its four-door sedan variant which has been one of the best-selling cars in the United States since 1989. The 1997 model is often referred to as the greatest car ever made. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, wagons, hatchbacks and a crossover.
In 1982, the Accord became the first car from a Japanese manufacturer to be produced in the United States when production commenced in Marysville, Ohio at Honda's Marysville Auto Plant. The Accord has achieved considerable success, especially in the United States, where it was the best-selling Japanese car for fifteen years (1982–97), topping its class in sales in 1991 and 2001, with around ten million vehicles sold. Numerous road tests, past and present, rate the Accord as one of the world's most reliable vehicles. The Accord has been on the Car and Driver 10Best list over 26 times.
Honda F20C engine
A mid-size car (occasionally referred to as an intermediate) is the North American/Australian standard for an automobile with a size equal to or greater than that of a compact. In Europe mid-sizers are referred to as D-segment or large family cars.
The automobile that defined this size in the United States was the Rambler Six that was introduced in 1956, although it was called "compact" car at that time. The mid-size class then grew out of the compacts of the early-1960s. For example, the Ford Fairlane was referred to at its introduction in 1962 as a compact intermediate because it was barely bigger than its close relative, the Falcon. General Motors' first entries in the class, such as the Oldsmobile F-85, Pontiac Tempest, and Buick Special were not mechanically related to the compact Chevrolet Corvair, but were similar in size.
Honda C engine
The F20C and F22C1 are inline-4 engines produced by Honda. They are one of the few Honda 4-cylinder automobile engines that are designed to sit longitudinally for rear wheel drive.
These engines are a distant relative to the F-series engines found in the mid 90s Honda Accord and Prelude. To get most out of the compact sized engine, Honda engineers utilized technology derived from Honda's racing engines. The F20C and F22C1 have two overhead cams with roller followers, a ladder-frame main bearing stiffener, a VTEC system for both the intake and exhaust camshaft, Fiber-Reinforced Metal cylinder liners (FRM), molybdenum disulfide-coated piston skirts for reduced friction, and uses a timing chain.

Honda's first production V6 was the C series; it was produced in displacements from 2.0 to 3.5 liters. The C engine was produced in various forms for over 20 years (1985–2005), having first been used in its then new Legend model, and its British sister car the Rover 800-series (and Sterling).
All C engines share in common a 90-degree V from bank to bank. Beyond this fact there is little to no similarity between the three drive train layouts. The engine family can be broken down into three sub families:
