Greetings, I bought one of these belt tension gauges (before knowing how to use it!) to check the timing belt tension on my Nissan VG engine. Nissan specs call for 13 - 15 mm belt deflection with 98 N (9.8 daN) of force. But the reference charts I’ve found only go up to 7.9 daN. Is there a way to “…

To be honest, I have never used a timing belt tension-setting tool. I just put as much tension as I can with one finger. This is sufficient tension to keep the belt from slipping, and is definitely not too much to the point which excess wear would occur. Timing belts don’t stretch like accessory …

From what I can tell there is a spring-loaded belt tensioner that sets the tension, no need for this gauge.

I don’t claim to know how to set your belt tension, just a pin-head diy’er, but it seems like you could create a chart of force vs deflection by experiment. If it appears to be a straight line, you might be able to use that to approximate other data points on the curve. I’ve never done that mysel…

Thanks for all the responses! I like the linear approach, but math isn’t me forte, so I gave up on trying to calculate the next sets of values. Definitely thinking of returning the “gauge”, I don’t like that the scale isn’t setup to simply dial in the amount of pressure, it has to be referenced off …

Make sure to measure the existing belt’s tension before removing it, then you at least have a reference to compare to.

Might, I stress might, be useful on old cars with V fan belts, definitely not for your Nissan. [VG30 & VG33 - Setting the tension for the timing belt. CORRECTLY!!]

In over 30+ years in the business and have done plenty of TB, taught many how to do TB’s and seen even more done by others, I have never seen that tool used… lol Always just used a straight edge and measuring tape etc or simply used a finger as noted above… You have what a VG30ET SOHC engine with …

Whenever I did a timing belt on any vehicle the test always involved a feeler gauge.

How do you use a feeler gauge to test belt deflection? Feeler gauge to set plugs, points, and valves, have done so. Belt deflection, can’t even guess.

Too late! But for the future (will hafta do this to a different vehicle soon), what would I use to measure the existing belt’s tension?
