Answer

Hello XXXXXXX,

I use a 13/16 wrench for the oil cooler lines. Watch out for the o-ring on the line. They fall off sometimes.
You can use a 1/4" ratchet with a short extension for the drain cock. Take the upper shild off first. will make it easer to access.

Draining procudere:

Caution: Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap while the engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out over the engine, fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not recommended for use at any time. Flammable antifreeze could cause a serious fire.

1. Place a drain pan under the radiator drain cock.
   
   Place the end of the tube in the drain pan.
2. After the engine cools down, remove the radiator cap.
3. Using a 1/4 in drive, completely open the radiator drain cock.
4. Allow the coolant to drain from the system until the flow stops.
5. Place a drain pan under the block drain hole plug.
6. Remove the drain hole plug from the engine block.
7. Allow the coolant to drain from the block until the flow stops. There may be more drainage from the radiator at this time.
8. Install the block drain hole plug.
9. Close the radiator drain cock.
