I am going to install a new radiator soon before my current develops any cracks or leaks.

I know how to do the replacement, but since i have an automatic i was wondering if i need to top up the ATF after i install the new radiator.

How much fluid is in the part of the radiator that cools the transmission. Also which fluid should i use and how do i top it up?

Or do i not have to worry about ATF top up?

If anyone can provide some knowledge it would be appreciated.

My Magna is a 2002 TJ series 2, advance v6 sedan, automatic 242,000km.
