Check the regularly updated Timing Belts section on our website to ensure that you are kept informed of any changes that may occur between issues of the Autodata CD. Timing belt replacement intervals Where possible the recommended intervals have been compiled from vehicle manufacturers' information. In a few instances no recommendation has been made by the manufacturer and the decision to replace the belt must be made from the evidence of a thorough examination of the condition of the existing belt. Apart from the visible condition of the belt, which is explained fully in the General Instructions/Toothed Timing Belts section, there are several other factors which must be considered when checking a timing belt: Is the belt an original or a replacement. When was the belt last replaced and was it at the correct mileage. Is the service history of the vehicle known. Has the vehicle been operated under arduous conditions which might warrant a shorter replacement interval. Is the general condition of other components in the camshaft drive, such as the tensioner, pulleys, and other ancillary components driven by the timing belt, typically the water pump, sound enough to ensure that the life of the replacement belt will not be affected. If the condition of the existing belt appears good, can you be satisfied that the belt will not fail before the next check or service is due. If the belt does fail, have you considered the consequences. If the engine is an INTERFERENCE type then considerable expensive damage may well be the result. The cost of replacing a belt as part of a routine service could be as little as 5 to 10% of the repair cost following a belt failure. Make sure your customer is aware of the consequences. If in doubt about the condition of the belt - RENEW it. Refer to the Toothed Timing Belts/Service Replacement section for further information relating to arduous or adverse operating conditions, inspection and service replacement. Replacement Interval Guide

2 Replacement Interval Guide Citroen recommend: 1992MY: The vehicle manufacturer has not recommended a timing belt replacement interval for this engine MY: Replacement every 72,000 miles under normal conditions or every 36,000 miles under adverse conditions MY: Replacement every 72,000 miles under normal conditions or every 48,000 miles under adverse conditions. 1997MY: Replacement every 72,000 miles under normal conditions or every 54,000 miles under adverse conditions. 1998MY: Replacement every 80,000 miles under normal conditions or every 48,000 miles under adverse conditions. 1999MY: Replacement every 75,000 miles under normal conditions or every 60,000 miles under adverse conditions. 2000MY : Replacement every 75,000 miles or every 10 years under normal conditions, or every 60,000 miles or every 10 years under adverse conditions. The previous use and service history of the vehicle must always be taken into account. Check For Engine Damage Check For Engine Damage CAUTION: This engine has been identified as an INTERFERENCE engine in which the possibility of valve-to-piston damage in the event of a timing belt failure is MOST LIKELY to occur. A compression check of all cylinders should be performed before removing the cylinder head.
