Bent upper core support

Has anyone bent there upper core support, and if so how did you go about getting straight. My hood, rad, fan, none of it lines up anymore because that support is bent forward. Any help would be great so I can get it back on the road.

How the hell do you bend it forward? Leave the hood up and drive really fast in reverse?

sorry i meant back toward the car (i was in a hurry when i typed that) I hit another car and went underneath it.It didn't touch the bumper, but hit the core support dead on. Sorry i tried like 4 times and couldn't get the pics to work. (Damn Dial-Up). I will try again later.

Pull the hood off, tie a rope, or preferably steel cable or chain to the radiator support and the other end to a stationary object (Tree, heavier vehicle, building), and put the car in reverse. Feather the clutch.

Oh so much potential for trouble. The tree can fall and crush you, or worse the car. You can severly injure/or kill a random bystander. I say go for it!


Just be careful. and good luck.

i too say do the tree thing. i bent mine pretty bad and i tied a 4 ton rope to a THICK *** tree and went in reverse slow at first then faster for more results. be careful you dont crack the support at the frame. good luck, mine still doesnt line up quite right. Jerry

I shouldn't have said rope...

I should have said I am not responsible for anything that happens to you, your car, your dog, your mother, or the tree... You're on your own.

I'd anchor the chain or steel cable to the crease in the radiator support. I'd back of very slowly...

In fact, disconnect the ignition system and bump the starter in gear to do the work. Much slower. More precise.

I will also point out that this is a VERY BAD IDEA (TM)... But then again, so is paying a body shop to use their frame straightener which does pretty much the same job.

I am not worried about anything happening except for cracking the core support or bending it to much. We have some big *** trees down here that no Rx-7 is ever gonna pull down and a 10000lb steel cable that is got gonna break. What I am worried about is that it my crack or something of that nature.

Don't do the reverse thing,

Pele, stop giving scoop like that to beginners

First read the entire post then PM me with questions:

Tie the chain or rope around the core support, put the car in neutral, roll it back until the chain or rope is tight, set the parking brake, and then stand and bounce on the rope or chain. this allows you to apply however much force you need without fear of ripping of the front end. If you weigh 180 lbs, bounce the rope by 6 inchs you have produced more force on it than almost any air hammer, or slide hammer could make. as it straightens out, release your parking brake, push the car back to re-tension the rope/chain and repeat until straight. do not use the "hook" to pull with it will punch holes in the sheetmetal. get yourself a couple of pieces of 3" or 4" "C" channel and use it to spread the force over a larger area, and then tie the rope around it.

you can also "bounce" the car setup the same but leave the car in neutral, leave about 6~8" of slack in the rope/chain and then push it backwards until it snaps tight, the shock that you will produce this way can be varied as required to pull out the front end, once again without ripping the front end off.

by varying the height of where it is tied to the tree, you can vary how it pulls on the piece and get different results.

Rockin... Much more controlled than my method. Don't listen to me, listen to this guy... Except when you have a 12A-Turbo laying about... Then don't listen to this guy.

I will give this my seal of approval.

thanks for all the advice guys, it is somewhat straight now. i don't think it will ever be totally right again. but the hood closes and it has an e-fan now, so no more clearing problems with the fan.
