Hello All,

I need assistance in getting off my fill plug on my 91 honda accord. It is on so tight. I can't move it. I tried breaker bar, tried my impact wrench (no room); nothing seems to work. Now I think I stripped it, but not that bad. I was wondering could I use a torch on the surrounding area of the plug. I heard filling from the backup light switch will work. Any suggestions!

 

Are you sure you are trying to loosen the fill bolt, because it shouldn't be on there that tight.

Personally, I wouldn't use a torch. I would try PB Blaster first.

You should be able to add fluid via the backup light switch, but the fluid level is determined by removing the fill plug. You can try to get it close, then take it to an oil change place or a shop to see if they can loosen it.

 

The steel plug oxidizes to the aluminum case. Put a short extension in the plug and hit it with a hammer. That should crack loose the oxidation enough to turn the plug. Use anti-seize on the plug when re-installing.

 

What PAHonda and Roader suggested are good.

Roader's suggestion is similar to what Honda suggests for stubborn filler bolts.

Generally, Honda's first suggestion is to grab an extension and attach a 17 mm socket to it. Place the socket over the bolt, and strike the end of the extension with a hammer. This compresses the sealing washer under the bolt, reducing the friction on the threads.

A 6-point socket has less chance of rounding off the bolt head than a 12-point socket.

 

that's my thought, too - wrong bolt. A breaker bar should have worked.


I now just take my '92 MT to local oil change place for oil, filter, and tranny drain / refill as single service.
I don't have level lift for tranny refill accuracy.
These yrs spec engine oil for tranny: 30W, 10W-30, 10W-40 (I have the '92 car and the owners manual)
so I can gently talk the shop into adding the tranny service (including oil) for $20-30, if I also buy their engine oil / filter change.

All around it saves hassle for me; I service tranny at 25k intervals. If I want a special oil I bring it.

 

Yes, I know that I am loosening the fill bolt. It is the bolt to the upper left of the drain bolt. I think I am going to have to fill through the breather tube or backup sensor. Is that a good option? If so, which is better? I know the breather tube is better for me to get to.

 

Remove the fill plug and "fill" thru it........

 

That SOB is stuck like chuck and would not move. No matter what I did. So I just removed the backup light switch and filled it from there. I put two quarts in it. It was bone dry because I just replaced my tranny. Car is running now. Don't look like there are any problems. Cross my fingers.
