There's a great YouTube video for the 2006 Acura TL out there. I thought that I might be able to get by with a 19mm socket, 1/2" impact wrench and extension but purchased this just in case. Glad I did--the impact wrench didn't come close. Ended up needing to use this with one 1/2" breaker bar to prevent the crank from rotating while I broke the bolt loose with the 19mm impact socket, 2x 10" impact extensions (resting on a jack stand for stability) and another 1/2" breaker bar. A 4' pipe over the breaker bar to provide extra leverage would have been helpful, but was able to get by without. Used a 1/2" 25-250 ftlb Tekton torque wrench to re tighten (181ftlb) when finished.
