How do you change timing belt on Renault traffic?

To change the timing belt on a Renault Trafic, you'll first need to disconnect the battery and remove any components obstructing access to the timing cover, such as the serpentine belt and engine mount. Once you have access, align the timing marks on the crankshaft and camshaft, then remove the old timing belt, ensuring to check and possibly replace the tensioner and idler pulleys. Install the new timing belt, ensuring it's properly tensioned, and reassemble all components before reconnecting the battery and running the engine to check for proper operation. Always consult the vehicle’s service manual for specific details and torque specifications.
