Hello Forum,
I read somewhere, not sure where, that the tension on a Brand New Serpentine / Drive Belt Tensioner should be around 23 Ft Lbs.
Based on a test I just performed, this is not the case, unless I tested a Bad New Tensioner.
The tension can be tested by using a Torque Wrench and a 14mm Socket, with the Torque Wrench setup for Counterclockwise (Typically Loosening...) Operation.
I tried this test on a Brand New from Toyota Serpentine Belt Tensioner.
Part Number 16620-0W101.
My Torque Wrench clicks prior to the Tensioner moving up until around 13 Ft Lbs.
It Moves a Little at 13 Ft Lbs.
It Moves a Little More at 14 Ft Lbs.
And the Tensioner Fully Moves / Rotates pretty much the entire way at around 15 Ft Lbs.
I test the Tension when doing a Timing Belt / Water Pump Service to make sure I'm not putting back on bad / inadequate parts.
This is the 1st Time I've tested a Brand New One.
If 15 Ft Lbs is the approximate Tension of a Brand New Tensioner, what Tension should be considered bad / not a passing value?
Anyone else doing this test?
Thank you.
Tom
