The FSM doesn't list a torque spec just says use the SST. Does anyone know the reasoning behind this and what is the spec really is?

Thanks

 

I don't know, but typically the purpose of that sort of SST is to prevent breaking off the connector with a regular socket. (like the O2 sensor or oil pressure sensor SST)

I've never removed a knock sensor, but I don't believe it blocks an oil or water passage. So it doesn't seal anything, and it just has to be tight enough to prevent it from jiggling loose. That wouldn't be much more than 20 ft-lbs, which is easy to exceed with a long wrench. So be careful.

 

Thanks for the input, your probably correct about the electrical plug and the SST. I think I will just make sure it is nice an snug by hand, being careful not to damage the plug connector. I'm surprised the FSM doesn't specify a torque. Thanks again.
