I'm a fairly strong guy...but I am twisting the hell out of these damn plugs with everything I got and I cannot BUDGE either of them (Yes, I tried the fill plug first), but I also tried to even loosen the drain plug even a tiny bit and nothing.

I sprayed some WD-40 on em...gonna let it soak for a while..hopefully that loosens them up.....Using heat on those probably is NOT a good idea hey?

Any other suggestions?

 

WD-40 won't work, it isn't a penetrating rust dissolver. You need some PB Blaster, or similar product.

With the right stuff, spray a bunch on, and then tap on the plug with a hammer. (not hard, just tap.) Do that a couple times, and then try and remove them.

No, you don't wanna use heat on aluminum....... that could be bad.

 

be careful on wrench size choice. the hex plugs are 10mm, not 3/8.

if penetrating oil doesn't work, look for a 10mm hex you can insert into an impact wrench. the shock of the impact 'should' break it loose.

(or a long breaker bar on a socket style holder)

edit - a little bit of heat might not hurt. just remember, aluminum melts at around 600 or so.

 

Got em loose, I want to go back in time and slap the crap out of myself for over-torquing those whenever I did this last, LOL.

Had to use both your ideas....Went and bought some actual penetrating oil, let it soak for 20 mins, then attached the longest ratchet handle i could find and let er rip....still took a crap-ton of force..

oh well, Cheers!

 

when you reinstall them, use a thread lubricant like RTV or liquid teflon. then just barely snug them.

 

...or something like never seize....

 

i like to use anti-seize on things that you torque down tight, or modestly tight, especially spark plugs and lug nuts.

for oil/coolant drain plugs, i like to use liquid teflon and just barely snug them. the teflon (or rtv in a pinch) will prevent seizing/galling, seals it up, and prevents back out.

 

Torque them to the proper spec. 35ft pounds and you wont have that problem again.
