bottom of radiator support rusted away ,along with air dam. will radiator fall?

The radiator has to be supported in some way. It can't hang there by the hoses.

If you are asking if this is something that needs urgent attention, the answer is yes, quickly, and before you drive it again. If the rad falls, you could have a crash, you could ruin your engine, transmission, or any number of other things, not to mention the injuries that may be sustained by you or others unfortunate enough to be nearby. This is not a repair that can wait.

RockAuto.com has the support for $200. Here's a link to a 5% discount --- http://www.cargurus.com/Cars/Discussion-ds544448

thanks guys. i thought it was attached at the top. i will strap it in. the bottom corners are still there.

Those bottom corners will not support the weight for long. You need to get that piece replaces as quickly as you can. You don't need a crash or to do serious damage to the car because the rad falls out. Also, even if there is no other damage you could ruin a perfectly good radiator for want of the proper support, and that is just going to cost you a bunch of money for nothing.

i got it . metal strapping .she not going anywhere now. i cushioned the bottom of radiator and the strapped to the top then attached strapping at top . good to go.now.
