So clear, so informative and, in such a short time! One of the best auto repair videos I have seen.
Great job.

This is an excellent video. Straight to the point and covers the problem and solution. Not a bunch of jibber jabber that just irritates you when you're trying to see what your problem is.

Thanks for the advice, Sometimes the school doesn't teach you this

Few things are sweeter than a to the point youtube video, where you can make out what they're pointing at and saying. *loud rock music plays as shaky camera with poor lighting gyrates around a finger after a five minute vlog intro* i always look out for 1a auto videos relating to my vehicles, keep'em coming.

Clear and concise walk-through on how to self diagnose what is leaking. Not a detailed how to to change the seal, but it gives a good idea of what's involved quickly which I really appreciated. Thank you for posting!

Thanks for this video. Now I have to figure out exactly where the leak is coming from. Its a mess at the back of the truck with fresh clear fluid. Its even dripping off the bottom of the gas tank.
