This is one job you really don't want to leave too late. If a cam belt (timing belt) snaps while the engine is running, it can bend valves, damage pistons, and turn a straightforward replacement into a costly engine rebuild - or a write-off.
Most engines in New Zealand vehicles are what's called 'interference' engines, meaning the pistons and valves occupy the same space at different times. The cam belt keeps them in sync. Every manufacturer specifies a replacement interval based on kilometres and age, and we'll check yours and let you know when it's due.
This is one of those jobs where the cost of prevention is a fraction of the cost of failure. Common vehicles we see for cam belt replacements include Subaru Imprezas, Honda CRVs, Toyota Camrys, VW Golfs, and Mitsubishi Lancers.
What We Cover
- Cam belt (timing belt) replacement
- Timing belt tensioner and idler pulley replacement
- Water pump replacement (recommended at the same time)
- Timing belt cover and seal inspection
- Crankshaft and camshaft seal condition check
- Timing system alignment and verification
- Balance shaft belt replacement where applicable
- Drive belt inspection and replacement if worn
- Coolant replacement (required when water pump is changed)
- Oil seal replacement if leaking onto the belt area
- Auxiliary component inspection while accessible
- Post-replacement engine timing verification
How It Works
Book in by phone or online and let us know your vehicle details. We'll look up the manufacturer's recommended interval and confirm whether your cam belt is due.
On the day, we'll carefully remove the old belt, inspect all associated components, and fit the new belt along with tensioners and any other parts agreed. The engine timing is precisely set using manufacturer specifications and verified before the engine is started. We road-test the vehicle to ensure everything is running smoothly before handing it back.
Pricing Guide
Cam belt replacement costs vary depending on the vehicle. Simpler engines like a Honda Jazz or Toyota Corolla are at the lower end, while more complex engines like a Subaru boxer or VW turbocharged engine are higher.
Including the water pump adds to the parts cost but minimal additional labour since the pump is already accessible. We always provide a firm quote for your specific vehicle before starting work. Give us a call with your vehicle details.
Why Choose Eastern Bays
Cam belt replacement is a precision job - get the timing wrong and you've got bigger problems than you started with. Our technicians have done hundreds of these across all major makes and models, from the boxer engines in Subarus to the overhead-cam setups in Hondas and the turbocharged engines in Volkswagens and Audis.
We always replace the tensioners and idler pulleys at the same time, because a failed tensioner will destroy a brand-new belt just as effectively as age would. We strongly recommend doing the water pump at the same time too, since the labour overlaps significantly - replacing the water pump separately later means paying for most of the same labour again.
While you're here, we can also take care of coolant flush, full service and diagnostics - everything under one roof at our Glen Innes workshop.
