Parts for the Holden WB One Tonner

Known issues

Rust is a major concern with WBs, particularly in the lower panels, floor pan, and around the windows. The inline-six engines are generally reliable but can suffer from worn camshafts and oil leaks. V8 engines, when fitted, are more prone to overheating if the cooling system isn't properly maintained. The Trimatic automatic transmission can also be prone to failure with a lack of servicing. Electrical issues are common, particularly with the wiring harness and connectors.

WOF tips

Key WOF (Warrant of Fitness) watchpoints include rust (especially structural rust), steering and suspension play (particularly ball joints and tie rod ends), brake performance (ensure brake lines and hoses are in good condition), tyre condition, and proper operation of all lights and signals. The condition of the load-carrying areas (for utes and vans) and the presence of seatbelts is also important.

About the Holden WB One Tonner

The WB Series is powered by the reliable 202 cubic inch (3.3-liter) inline-six engine, with some variants offering the more powerful 253 or 308 V8. Owners should be vigilant about certain parts that often require attention, such as spark plugs, filters, and brakes, especially as service intervals approach. The cooling system, for instance, needs a close eye around the 150,000 km mark where replacement of the water pump, thermostat, and radiator hoses should be considered. Regular oil servicing can also enhance your engine’s longevity—don’t forget to check your oil service kit when it's time for an oil change!

Common issues faced by WB owners include rust in lower panels and around windows, as well as potential overheating with V8 engines if the cooling system isn’t adequately maintained. Keeping your braking components updated is crucial, given the importance of maintaining safety—consider our front and rear brake service options that ensure your WB performs beautifully under load. For additional assurance, make sure to regularly replace filters and inspect your electrical system to avoid any hiccups on the road. Don’t hesitate; check out our categories on cooling, braking, and filtration for quality parts tailored for your WB.
