living in the Northeast my g has a lot of rust. I bought new hardware for the transmission pan(drain bolt + the 10 mm bolts holding the pan). I looked under the car today and oh boy so much rust around the drain bolt and the 10 mm bolts really scared of stripping. Currently at 145k miles. Any tips or suggestions or just spray PB and pray i wont strip? This is also going to be my first time doing a drain and fill.

 

Make sure to ONLY use a 6 point socket. The only bolts I've ever stripped heads on in my entire life were because of 12 point socket on a 6 point bolt. If you own an Audi then yeah you're going to need 12 point sockets for those 12 point bolts. If you own a Nissan you should own only 6 point sockets.

Other than that give them a couple clicks with a battery impact and they will probably pop right off, using a wrench you can use a 19mm wrench and tap pretty aggressively on the socket once you have it seated on the nut to crack the rust off if you don't have access to a battery impact.

I wouldn't use an air wrench impact, those things typically operate 800-1000 ft lbs torque and feathering the trigger still yields 80 ft lbs torque on the second click on my Ingersoll-Rand, that will literally snap the head off the transmission bolts in 1 second. A battery Makita/DeWalt/Milwaukee is only capable of 80 ft lbs max for the smaller impact drivers, you can feather the trigger and achieve 5 ft/lbs torque. Check the specs on the tool you're using.

 

I think i stripped like 3 of them taking off the under carriage. I guess wish me the best tomorrow.

 

You should be very proficient at drilling/tapping holes by the time you're finished

 

any idea how to remove this bolt near the O2 sensor(this is the one hear the passenger side? https://photos.google.com/photo/AF1Q...m57Gt5wxnTeMIm

I tried some universal joints + a 10mm and it doesnt fit.

I stripped one bolt so far i broke the rest. I think im pretty close.....

 

Use this button and load the photo directly into the message body, your Google photo link does not work.

 

heres a pic of that bolt

 

You can bend the O2 sensor brackets out of the way

 

i think ill just use an offset wrench... not willing to bend my o2 sensor bracket lol.

 

If you’re just starting out as a mechanic, investing in good quality basic tools will save you headaches down the road, especially reliable ratchets, sockets, and wrenches that you’ll use every day. A decent torque wrench and a set of quality screwdrivers make a big difference on the work you do most often. Once you have the essentials covered, you can slowly add specialty tools as you need them without blowing your budget.
