This question relates to my 2 Toyotas and not my SC300. (However, I may need to know this in future for the SC300.)

I have a Burroughs Belt tension gauge Model No> BT-33-73G. However, the Toyota manuals state that I should use a BT 33-73F (not G) to set the belt tension. Who knows what the difference is?

I thought that it might relate to belt thickness but can find nothing on the web about this?

Any help greatly appreciated.

exactly what belts are you referring to?

 

The aircon, power steering and alternator belts on a Previa.

 

should have around a 1/2 inch of deflection at it longest span......Previa.......I believe they have large wing nuts that you will have to turn to achieve proper tension
