First time owner Questions
Hello all,
I was gifted a 3rd gen Montero 3.5L 4 speed auto. I’m kindly asking for assistance as to
- whether I need to replace the component in photo number 2
- what the reservoir in photo number 1 is called and its function.
- Additionally the 4wd indicator on the dash sometimes the c/d orange light stays solid, any idea what that could mean?
Loving the car and want to get it to tiptop condition
Thanks in advance
