Introducing the Chevrolet C20, a quintessential American pickup from the late 70s. This robust workhorse made its mark on New Zealand roads, known for its sturdy build and straightforward mechanics. With its ability to tackle tough jobs while adding a touch of Americana, the C20 has been an essential part of farming and construction throughout the country. Whether you're already an owner or are considering adding this classic beauty to your fleet, here's what you need to know about its performance and maintenance.
Rust is a significant concern, especially in coastal areas. Check the cab corners, rocker panels, and around the wheel wells. Engine oil leaks from seals and gaskets are common with age. Suspension components like ball joints and bushings can wear out, affecting handling and alignment. The original braking systems required attentive maintenance and upgrades to modern standards improve safety substantially.
Expect scrutiny of steering and suspension components. Rust in structural areas will be an immediate failure. Brakes must be in good working order, with adequate stopping power and balanced performance. Lights and indicators need to function correctly. Windscreen wipers and washers are checked too. Also, ensure the chassis number is clearly visible and matches the registration papers.
The Chevrolet C20 is powered by a range of inline-six and small-block V8 engines, known more for their reliable torque than raw power—perfect for hauling everything from heavy machinery to equipment. With both automatic and manual transmission options available, dependability is key, especially when properly maintained. While the leaf-spring suspension allows for excellent load-bearing, it may present a rougher ride compared to modern pickup trucks. Keeping your C20 in prime condition means staying proactive with maintenance on essential components.
Pay attention to specific parts that commonly need replacement, such as brake pads, rotors, and the suspension components. Service intervals for engine oil changes are generally recommended every 5,000km to 7,500km to ensure maximum protection and performance. The cooling system, for instance, requires regular checks around the 150,000km mark—including the water pump, thermostat, and radiator hoses—to avoid overheating and other issues.
