#Audi timing belt tensioner manual
The timing belt and manual tensioner unit at a minimum must be replaced during scheduled maintenance intervals to maintain reliable and safe operation.
#Audi timing belt tensioner upgrade
Timing belts may also increase/decrease in size minimally during seasonal temperature changes, always check tension and adjust as necessary during heavy temperature fluctuations.Īlthough the IE manual timing belt kit is an upgrade over the OE setup, be sure to follow the factory timing belt replacement intervals. Timing belts tend to "stretch-in" after installation, IE recommends you check your belt tension often (every oil change) and adjust if necessary. The IE manual timing belt tensioner is a much more reliable timing upgrade over the stock hydraulic setup, however, this is a performance timing setup designed for performance engines and requires maintenance to ensure proper long-term operation of your timing system. This setup is proven on many street and race applications and is used by VW/Audi 2.0T FSI successors after the 1.8T engine was discontinued. This tensioner is set to proper timing belt tension and tightened securely into place. The auto-adjusting tensioner is then replaced with a traditional style manual tensioner. This two-part timing solution includes a new in-house CNC machined aluminum idler bracket that replaces the hydraulic piston assembly. The IE Manual Timing Tensioner Kit is designed to give you timing confidence by completely replacing the 1.8T timing belt tension system with performance-minded parts. Many of the available non-OE tensioners worsen this issue further with cheaper components, lack of quality control, bad tolerances, and awful surface imperfections that further lead to rapid degradation of the hydraulic o ring. The piston arm on the tensioner is sealed with an under-spec o ring that commonly wears out, cracks, rots, or leaks leading to the instant discharge of the hydraulic fluid resulting in complete engine failure. Unfortunately, this design has been a constant source of complete timing failure and one of the weakest links on the 1.8T platform. This hydraulic tensioner has a gas-charged piston that provides tension on the tensioner roller, designed to increase/decrease tension automatically. The vehicle is road tested to confirm normal operation and a service sticker is affixed to the engine noting the date of belt replacement and the vehicle mileage.All 058 1.8T 20V engines are factory equipped with a hydraulic style timing belt tensioner.Upon completion of the installation, the engine crankshaft is turned by hand 720 degrees and the correct position of the timing marks on the crankshaft and the camshafts is confirmed.Installation of the new timing belt includes all of the above steps, performed in reverse, following strict guidelines to assure camshaft and crankshaft (and balancing shaft, if equipped) are in perfect alignment after tensioner has been set.If the engine cooling system thermostat is only accessible with water pump replacement, the thermostat should be replaced as well. If replacing the water pump, do so at this time, and of course drain the cooling system first.Remove timing belt tensioner and idler pulleys. Lock camshafts, as required, and note position of camshaft timing marks. Remove all accessories interfering with the removal of the timing belt covers.Once the engine is cold, set the crankshaft to top dead center with the number one piston on the compression stroke.How do mechanics replace the timing belt?Įngine designs vary, and thus the replacement procedure will vary, but broadly, the procedure is as follows: If your car has an interference engine, replacing the timing belt according to the maintenance schedule will minimize the chance that a belt failure will cause engine damage.
These engine designs are referred to as interference engines. On some engines, if the timing belt has jumped, the pistons and valves can collide and there will be noise and damage. Project Time: 5 hours Tab: 200 Talent Tools: All of them Parts Required: New Timing belt Performance Gain: Peace of mind Complementary Modification: flush radiator The need to change the timing belt is one of the primary reasons the average home mechanic might tear into the front of the engine bay of a 1. Should the belt jump, the engine will run poorly and perhaps not at all. After many tens of thousands of miles, the teeth can wear or break, or the belt can stretch, thus causing the belt to jump position on the crankshaft or camshaft gears. The molded, reinforced teeth on the timing belt engage gears on the crankshaft and camshafts. Occasionally, timing belts can break, or skip, while the engine is running. Engine stops abruptly or will not start.Your vehicle owner’s manual should state the specific service interval. If an engine is equipped with a timing belt, the timing belt must be replaced at the service interval specified by the vehicle manufacturer regardless of whether or not any problem is visible, typically in the range of 60,000 to 90,000 miles.
