Got under the car the other day to drain the mineral oil out of the manual transmission (time for synthetic). Wasn't able to loosen the drain nut. I even tried an 18" breaker bar. Any ideas? WD40 didn't seem to help - perhaps because it is a recessed nut and the oil can't seep in the threads. Local dealer says they are willing to try but they want 1 hour labor ($75!!).

LOL! The title didn't sound right! :)

Anyhow, go to any local mechanic and ask him/her to just loosen up both plugs for you. I'm sure they won't charge you anything more than $10 for the effort.

depends on the shop. If you are a good customer, they may do it for free or very cheap, like $10. Many shops have minimum charges though, because in reality, it just is not feasible to do 5 minute jobs and charge for 5 minutes work.

Hmmm, applying a cloth soaked in Coca-Cola to the rusted bolt for several minutes. The active ingredient in Coke is phosphoric acid. Its pH is 2.8. It will dissolve a nail in about 4 days.

Mythbusters busted that nail scenario a few weeks back. Pb blaster has worked well for me in the past. Spray it on, let it soak in... do this for a couple of days, you don't want the bolt to break off.

I live in Florida, what's a frozen nut?

Peace,
Mark

do squats over a tub of ice water :confused: :eek: ;)

I second the PB Blaster or Gunk Liquid Wrench.

I was able to loosen mine with a regular 1/2" drive rachet and a rubber mallet. Apply downward force on the rachet with one hand while pounding the rachet with the rubber mallet. Careful not to hit your pinky. ;)

ha ha this reminds me of the time I sheared a half inch drive ratchet (thank for craftsman) while trying to break my axle nut loose. Later during that same episode I got a bigger breaker bar and sheared the head right off another bolt.

I believe you have a frozen recessed bolt, not a nut...good luck with your bolt, amputate your nut before the infection spreads ;)

We sheared a 1/2" drive impact socket trying to losen the fill plug on a tranny once... craftsman as well...
