It depends on the year. 41-48 used a 10mm from what I can tell. Anything else should be 14mm
The automatic transmission drain plug for most Toyota vehicles is a 10x1.5 thread size, with a head (hex) size of 14mm. You can use a 14mm open end wrench, or a 14mm hex socket, whichever is easier.
The 1.4Tdci DuraTorq engine's sump plug requires a 14mm socket or cranked ring-spanner. Luckily, a 14mm spark-plug socket can be found in most motorists' tool-box. 14mm is also equivalent to 7/16 " Whitworth.OOps! I got the above wrong! I meant a Spark-plug socket for 14mm spark-plugs (there are little 10mm spark plugs for lawn mowers and such) and that is actually a modern 21mm or old 7/16" Whitworth. Of course, the questioner is most likely asking about one of the older diesel engines - which are quite different.
you pull off the ht lead and then use a long reach socket to undo the spark plug. its a 10mm or 14mm spark plug socket i think. all this is under the cover ontop of the enigne i think. when you do them up, only nip them to 10-12nm of torque or it can damage them.
the plug head is 14mm, the threads on the bolt should be about the same size in order to fit the welded nut in the bottom of the oil pan
14mm
14mm
Oil pan to engine block I believe is a 10mm head, and the drain plug is 15mm head.
14mm
14mm - 1.5
14mm or 13mm
14mm
It is in the center bottom of the bike. The plastic pan has a hole in it and the plug is right there. You can take out the (6) 10mm head bolts to remove the whole pan if you prefer. The plug is a 21 or 22 mm.
