Hi everyone it’s been a while since I posted technology has moved on and I was wondering if anyone has used a hertz frequency tester to set the timing belt tension on a 5.0 if so what’s the frequency? TIA Nigel

It was discussed previously

General consensus is every 50k-60k miles / 5-6 years, whichever comes first.

However, I changed the TB in my 87 back in 2017 and don't really have any plans on changing it this year.

Keep in mind, the actual "belt" is the most reliable part of the timing belt system. The rollers, tensioner, water pump etc... are just as if not more important to be changed along with inspecting the cam gears for wear & replacing if necessary.

Also don't forget that later models have a sensor for timing belt slack...I don't recall from which years foward...

I ran the same belt from 2006 until 2023 and it looked virtually new. As for miles, I probably put 10K during that period (including some seriously hard driving) and the car was in a hot and dusty environment for a good part. When I eventually changed it, I inspected the rubber and it was barely starting to show dry rotting… This is why a properly setup belt with the correct hardware and sticking to OEM components do make a difference I feel in some areas.

I keep repeating what others have said, just ignore me

The OP asked a question about the sonic frequency of a correctly tensioned belt - in other words the sound one hears if the belt is plucked.- not the frequency of changing it out!

I seem to recall a pitch of E2 was quoted and some lower frequency around 50Hz for when the alarm goes off. For those interested but somewhat clueless- Middle C on a piano is known as C4 because it is the 4th octave on a piano and as its name suggests the key is in the middle of the piano- this note is pitched at 261.63 Hz. The frequency halves for every octave lower so C3 is around 130hz and C2 65Hz. By comparison my concert flute's lowest note is C4 and its highest pitch recognised note is C7.

If one knows the correct frequency then measuring it is not difficult in this day and age with commonly available technology. I think i will stick with my Kempf tool though!

Bonjour,
i used to rig the tension at 90Hz + or - 10 Hz. But it is time consuming if you do it with the mic of your phone. So I bought a Kempf tool,.. much quicker…
cheers,
