    2003 3.2L - radiator hose that leads to reservoir

    Hey guys, I was attempting to replace my tensioner pulley and accidently broke some part on my radiator. Its the brass connector that connects the top of the radiator to a hose that leads to the reservoir. Do any of you know if this is something that i can just remove w/ an extractor and replace? Or, do i need a whole new radiator? I've attached some photos.

    I checked a few '03 CTS radiator schematics and it seems that the broken part is not available separately. Sorry, I know it's not what you wanted to hear...

    Rippy can probably confirm that, but I think CT Essense is right.... you are probably on the hook for a new rad. Shit happens but look at it this way... Now you can avoid the whole "transmission cooling line popping off the radiator because the fitting broke" debacle and save yourself a potential headache

    wicked ghost is right...the cooler line always blows off and this is a opportunity to fix it before it breaks.. i forget the price of the rad but its 250 or 350 i think..check with rippy, but then you still need your tranny lines attached and i dont know how to do that, i had the dealer attach the lines.

    other option if you really want to save that rad is drill it out, tap it with threads and have a fitting made you can screw in there then attach that line back on... i think that is just the overflow return hose or something like that.

    i think you are better off changing out the rad tho.

    ...Or you can take it to a Radiator Shop and have them repair the nipple. Prolly an easy, fast, cost effective fix.

    Re: 2003 3.2L - radiator hose that leads to reservoir

    Thanks for all of the replies guys. I am going with a new one. a couple of other connections broke as I was trying to remove the hoses. They pretty much broke into pieces as i was trying to remove the hoses. I think it was going to mess up soon anyway so it was probably best that it happened this way rather than leaving me stranded somewhere.

    @ghettomike Is attaching the transmission cooling lines not something i can do myself?

    This happened to me as I was installing the Throttle Body after cleaning.

    The repair job is not hard at all. You have to reem out the broken piece that was left on the tank. I used a drill bit about the same size diameter as the plastic nipple. I slowly turned the drill bit with a pair of pliers, applying a little force. The area where the nipple attaches to the tank is plastic, so it doesn't take long to reem out.

    BTW, take the remaining nipple piece out of the hose,..and dont lose it. You'll need it to insert it back into the tank after youn reem the broken piece out. The new hole has to be a little larger in diameter than the nipple for insertion. Insert it to the tank about 1/4" and use JB Weld to bond the nipple in place. Dab the outside of the nipple with a little JB Weld to bond within the hole and then around the nipple where it attaches to the hole. Let it cure well. Reattach the coolant hose, start the car and make sure it doesn"t leak.

    I hope this works for you as well as it worked for me.

    Sorry to hear that. Wish I would've thought about it sooner when it first happened to you.

    I can't believe the damn think is made of plastic, including the upper tank. Anyway, Good luck with yours.

    i didnt attach mine for a couple reasons, i needed to have my tranny filled and i was getting a pan and filter service done on it, also there is a tool that is needed to attach the line and i didnt have it. i had it towed to the dealer for it.

    Did it cost you much to get the lines connected?
