I don't even know what the hell it is.
Searched on LMR's site and there are zero hits for "mustang belt pre tensioner". There are belt tensioners, but no pre tensioners. Could this be the problem?
Slow day today, lock up day number 30 or so and everyone is getting a little stir crazy?
I just reinstalled my A/C belt yesterday. No tensioner used. The belt stretches over the pulleys. You crank the engine by hand while guiding the belt into place.
This is the first stretch belt I have worked with. Worked well
