Man, I'm sorry you had the problem. Yeah, getting to that sensor is a real PITA. And the studs and nuts could have been stainless steel ... but that would have cost 5 cents!
Being the mechanic for all my extended family ... I get to work on many brands. They all have shortcomings. I still usually prefer Fords ... but I do a lot of re-engineering over the years if I keep one for a while ... and changing fasteners is high on my change list. |
