there's always enough time to do it over again...
NOBODY touches my cars until I have given up or cannot do the work (and that hasn't happend in years)-
I had a tire store mount and balance my summer tires today (no Coates 20-20 machine) on my Jeep TJ, and even though I could have sat in the air conditioned waiting room watching 'I Love Lucy', I stood outside the bay in 95 degree, humid weather watching the 'mechanic' mount, balance, remove and install tires-
he at one point said to me, 'do you take these off and on alot'? I said the last time off was Feburary, when I did front and back brakes for inspection, and I asked 'why'? He said that, 'maybe some studs might be 'cross-threaded'! I said to him, 'Well, it's a real good idea to hand-start lugs before you hit them with a gun'- duh...it is a matter of record, and I watched him. so when I have a problem, I will make it an issue.
But, why let anyone do what you can do? If I'm not doing the work, I'm paying, so I'm gonna pay attention-lucky it didn't cost you more than anxious moments, an all aluminum engine is very unhappy at high temps.
Give them hell, embarass them, consider it a lesson learned. Just reinforces what I know-nobody is gonna care as much as you, try to do it yourself-it's your ride.
