![]() ![]() most of those were tensioner, water pump or accessory drive belt failure related an none that he thought atmospheric deterioration was suspected. He himself said they had very few belt failures in any case. I spoke to my trusted independent and he said the reason for the time limit was some instances where atmospheric pollution/ozone MIGHT have been a factor in belt failure and they introduced it to be on the safe side. When I bought the car in fall 2010 I checked with VW and various independents and was informed that it had been revised to 80K or 4 years whichever is first and this age limit applies to all VW group cars in the UK In the handbook the belt interval for my 2007 1.9TDI Golf was 100k miles with no time stipulation. (The Bearings and seals of the water pump are what wear each revolution of the belt)Ī timing belt job ~150 - 200 dollars is far cheaper than an engine re-build due to a timing belt snap. It is usually recommended to replace the water pump at the same time as the TB is being changed out. The same thing happens, as the belt is surrounded by ordinary air, over time. The Pencil Eraser will loose its "rubbery-ness' over time and get very hard due to the UV rays. Drive belt and Tensioner also known as Serpentine belt, Accessory Belt, Alternator Belt, Air con Belt, or fan Belt, in this video i will show you how to chan. Try Using the rubber to erase a pencil mark after 1 year. Leave the tip exposed to bright sunlight like a desk window gives. Try this : Take a new pencil that has a rubber eraser on the end of it. What happens, is the AIR and Ozone attcks the rubber, and makes the rubber no longer pliable. ![]() This translated to an AGE of 3-5 Years, and if you check your owners manual, it will list a Timing Belt Change at approx every 60-80,000 Miles for its scheduled service. When this happened, then the original belts that were installled with the first TDIs were specified for 60,000 Miles (100,000 KM). Tensioners, idlers and dampers all keep your engine running smoothly by adjusting the timing belt or camshaft so that its properly synchronised at all. However, depending on the manufacturer of the belt, improvements were made in the chords that were impregnated in the rubber, so that they stood up longer than 100,000 miles. When the engine manufacturers changed from cams driven by a chain, and adjusted by tension eccentrics in the path of the chain, to rubber, that was fabric interlaced, it was included on most small engine blocks to change the Timing Belt 100,000 Miles / 5 Years. It's best just to do it right, but if you don't, you'll probably be alright. It's like when your diesel light goes on, it's getting close, but you still have some left.Īgain I know there are plenty of stories of failed timing related fails, I get it, don't bash me, I'm just willing to bet most, parts as well, last way longer than everyone freaks out about. It's not like the estimated interval is by the exact mileage, of course there is (most of the time) a cushion. I get its better to be safe than sorry but I'm also willing to bet that 98% of the time you're perfectly ok with keeping your belt and parts much longer than recommended. That being said, whether good luck or not, I've gone a good 50k over the recommended intervals and everything was just fine, and the belt and components seemed to be ready for another 50k, although ya never know.
