Oil pan plug size?

Hello all,
Trying to change the oil on a 1999 isuzu rodeo ls. Does anyone know the size of the oil pan plug, its on there pretty tight and i cant get it off.

thanks

Not sure if it's the same as my 93. Last time I checked, it was 20mm and I ended up using a large adjustable crescent wrench.

Mine was a 22mm the aftermarket replacement is a 17mm

Also use the power of levereage.

I keep 3/4 copper pipe 1-2 feet long and put that on the end of the socket wrench. It makes it way easier to remove the plug.

Careful when tightening. Don't use the pipe for that. It will over tighten.

Cheers

mine is a rodeo 2004 and pan plug size is 22mm.
