More info about cambelt replacements
The cambelt, also known as the timing belt, is a critical component of a vehicle's engine. It is responsible for synchronizing the movement of the engine's valves and pistons, which allows the engine to operate efficiently and safely.
The recommended interval for cambelt replacement varies depending on the make and model of the vehicle, as well as the type of engine and driving conditions. Generally, it is recommended to replace the cambelt every 60,000 to 100,000kilometers or every five to six years, whichever comes first.
The cambelt replacement process involves removing the old belt and installing a new one. It is also recommended to replace other related components, such as the tensioner, idler pulley, and water pump, at the same time to ensure that the entire system is working optimally. This can prevent costly repairs and ensure that the new cambelt lasts as long as possible, and can avoid having to work on the same part of the engine again in the future.
Auto Super Shoppes have the necessary equipment, training and experience to avoid potential severe engine damage, which faulty cambelts can cause. We will keep records of the cambelt replacement, including the date, mileage, and details of the work performed, to ensure that the vehicle's maintenance history is up to date.
If you do not know when your cambelt was last replaced, contact your closest Auto Super Shoppe as soon as possible to prevent avoidable engine damage or failure.
Frequently Asked Questions about Cam Belt & Timing Belt Replacement
What is a cam belt / timing belt?
A cam belt (also called timing belt) is a critical engine component that synchronises the rotation of the crankshaft and camshaft, ensuring valves open and close at the correct time during engine operation. Made of reinforced rubber with teeth that grip gears, it's essential for proper engine function. Some vehicles use a metal timing chain instead, which typically lasts longer but costs more to replace when necessary. The cam belt is hidden under covers and requires professional inspection.
When should the timing belt be replaced?
Timing belt replacement intervals vary by manufacturer, typically ranging from 60,000-100,000km or 5-7 years, whichever comes first. Check your owner's manual for specific recommendations. In New Zealand's varied climate conditions, belts may deteriorate faster than in other regions. Never exceed the recommended interval, as belt failure can cause catastrophic engine damage in interference engines. Many mechanics recommend replacement at 80-90% of the manufacturer's interval as preventative maintenance.
How much does a cam belt replacement cost?
Cam belt replacement in New Zealand typically costs between $500-$1,200, depending on your vehicle make, model, and engine configuration. This price usually includes the belt, tensioners, idler pulleys, and water pump replacement (often recommended simultaneously). While this service represents a significant maintenance cost, it's far less expensive than repairing engine damage caused by belt failure. Many workshops offer payment plans for this essential service.
What happens if my timing belt fails?
If your timing belt fails while driving, your engine will stop immediately and may sustain severe internal damage. In "interference" engines (most modern vehicles), valves and pistons occupy the same space at different times, so belt failure causes them to collide, resulting in bent valves, damaged pistons, and cylinder head damage. Repairs often cost thousands of dollars, sometimes exceeding the vehicle's value. Non-interference engines typically avoid this damage but still require towing and belt replacement.
How long does the replacement take?
A standard timing belt replacement typically takes 3-5 hours, depending on your vehicle's engine design and accessibility. Some compact engine bays or complex designs may require additional time. The job involves removing multiple components to access the belt, replacing it and associated parts, then reassembling and testing. Most Auto Super Shoppes complete the work within a day, and many offer courtesy vehicles for your convenience during longer jobs.
Are there signs that the timing belt is wearing out?
While timing belts often fail without warning, potential signs include unusual engine noises (ticking or slapping sounds), difficulty starting, engine misfiring, oil leakage near the timing cover, or visible belt damage during inspection. However, these symptoms may indicate other issues as well. The most reliable approach is preventative replacement based on manufacturer recommendations rather than waiting for warning signs. Regular engine servicing may identify potential problems before failure occurs.
