where do you drain the radiator fluid?

My dad wants me to help him with his radiator fluid change. It is a 2002 8 Cyl. I looked underneath and found what I tought was a plug. It will only go about 1/2 turn. I dont want to force it because It doesnt look like it goes any further. No fluid comes out. (cap was removed)

Anyone done theres that knows. Otherwise I will probobly just undo the bottom hose.

Thanks in advance
Mike

should be on the right hand side on the bottom facing the engine wont turn much but should drain the water out

Hell, just do it like we all do. Take the bottom radiator hose off. You'll get all your fluid drained in about a minute (or less). Then just slip it back on, tighten the clamp, and fill 'er back up.

Better yet, why are you changing the water on a 2 year old truck?

It has clase to 100,000 miles already. Is it still necesarry to change it? Mabye I will have him check his manual.

Change it whenever you feel like it. If there is rust in it, it does need changing.

I change mine every 18 months, probably a bit anal but I've never had a cooling problem in any vehicle I've owned. Except for that one time that the freezing rain totally blocked my grill and no air got to the radiator. :)
