It is the same tube the dipstick tool goes in to.
Take the black plastic engine cover off and you will see a tube with a black cap on it.
The black cap should have a red locking tab on it. The tab will have to be broken off
to release the black cap. The tab is only $1 or less to lock the cap back in place once
proper levels are achieved. Only use an approved fluid or bad things will happen.
