The tensioner pulley rides against the belt, but it's this spring applying the force that holds it there. Springs lose tension with age and heat cycling, and a tired one means the tensioner isn't pressing as hard as it should no matter how good the tensioner itself is. It's a small, inexpensive part doing an essential job on a car where getting to it costs a weekend.\u003c\/p\u003e\n\n\u003cp\u003eHonda lists this as the timing belt adjuster spring in their documentation, so if you're working from a parts diagram, that's the same part.\u003c\/p\u003e\n\n\u003ch4\u003eA New Tensioner Deserves A New Spring\u003c\/h4\u003e\n\n\u003cp\u003eThis is the whole argument, and it's why people who do this job properly buy both.\u003c\/p\u003e\n\n\u003cp\u003eYour tensioner and its spring work as a pair. The tensioner provides the pulley and the pivot, the spring provides the force. Replace one and reuse the other and you've only fixed half the system. A brand new tensioner working against a spring that's lost tension over fifteen or twenty years isn't applying correct pressure to your belt, which is the entire point of the assembly.\u003c\/p\u003e\n\n\u003cp\u003eAnd springs do fatigue. Constant load, constant heat cycling, decades of both. It's not dramatic wear you can see by looking at it, which is exactly why it gets skipped.\u003c\/p\u003e\n\n\u003ch4\u003eDo The Complete Timing Service\u003c\/h4\u003e\n\n\u003cp\u003eReaching this on a mid-engine NSX is most of the labor on the job.

Plenty of NSXs cover very few miles per year, which leads owners to assume they're nowhere near due for timing service.\u003c\/p\u003e\n\n\u003cp\u003eSprings and rubber age on a calendar, not just an odometer. A spring that's low-mileage but twenty years old has been under constant tension that entire time. If you can't remember when the timing service was last done, or you bought the car without records, treat it as overdue.\u003c\/p\u003e\n\n\u003ch4\u003eUse The Genuine Part\u003c\/h4\u003e\n\n\u003cp\u003eSpring rate is the entire specification here. A spring that applies the wrong force means belt tension outside what Acura designed for, either too loose or too tight, and both cause problems on an interference engine. This is the exact part Acura spec'd, and given what it costs relative to the job, there's no argument for anything else.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1991-2005 Acura NSX, manual and automatic.\u003c\/p\u003e\n\n\u003cp\u003eCovers both the NA1 and NA2 chassis.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Grab One\u003c\/h4\u003e\n\n\u003cp\u003eThis is for the NSX owner doing timing belt service and doing it completely. It's the smallest line item on the parts list and one of the easiest to overlook, which is exactly why it's worth adding to the order.
