The new Gates belts are in ! Most notably, the high performance "racing" timing belt . The old belts, last installed
nine years and four months ago , but only about
12 K miles or so on them since then.. ( I know, I know...I haven't really driven that car other than short weekend runs on twisty canyon roads :glare: ) looked and felt barely used and aged; upon very close inspection, including the inverted stress test they did not have a single hairline crack, were still extremely pliable, no wear on the teeth , although ..they were just slightly drier than the brand new belts seemed to be..maybe by about a 25 % factor. So probably may have been ok for yet another 50% of that time and mileage, but why take that big of a $$ gamble ?! And maybe the high performance belt will last 100 K miles and 25 years, whichever comes first, but not taking a chance on that either, I'll was thinking maybe change it at 75 K miles or ten years, whichever comes first, but then realized the balance belt is not the same high performance composite, so I may be forced to change both belts anyway at 45 K mi or five years , no matter what..
