    So I was pulling onto the highway and heard a squealing noise. Made it home and decided to check all the pulleys. In doing this I guess I put too much pressure on the radiator hose with my arm and the spot at the top of the radiator where the rubber hose connects broke off. Any way to fix this without replacing the radiator? I’m on a huge time crunch. Thanks

    Could try some jb weld or equivalent for a quick temporary fix if you don't need to go far

    I think you might be due for a replacement radiator from Denso. That plastic already appears brittle from what you described. I wouldn’t chance it with your cooling system by using a temporary fix, but that’s me.

    Thankfully, they’re super easy to replace.

    There's no way you're ever going to get a good seal and expect to hold pressure, and I don't think JB Weld is the answer. Look at the color of that radiator plastic. It's done. Just be thankful you don't have the dreaded "strawberry milkshake". Replace the radiator.

    That brown color is indicative of the aging plastic. Time to replace.

    Dude. That radiator is brown from age, it's supposed to be black. It's probably about 5yr/50k miles overdue for replacement, if not double that. You should be proactively replacing it at every timing belt change, if I'm being honest.

    Don't jury-rig your shit. Replace the radiator as it should've been done. If that part cracked, the transmission pass-thru line is probably not far away and you DO NOT want pink milkshake and a dead transmission!

    It shouldn't take more than 30 minutes to replace the radiator if you bust a hustle.

    Summit racing has denso for $160-190, can’t recall. Use the factory side rails, they fit better than what comes with it. Personally I wouldn’t recommend a repair unless it’s just to get to your work area. Mine split right on top of shroud, smelled coolant, but had to pressurize system to see the crack. The hoses should be good though.

    Call around town. Someone is bound to have a radiator for it. You can probably change it out in an hour, there's not much in the way.

    Please dispose of old coolant properly, it kills animals very painfully.

    Just doing a +1 on what others have said. That brown color means it's done for.

    You're actually fortunate it's broken there. This particular design has the transmission fluid flow along lines inside the radiator. Those connections break when it gets old and brittle. Then you have coolant mixed in with the transmission fluid. Look up 'pink milkshake'.

    A new radiator is less than $200 plus obviously new coolant. Super easy job.

    And now it's fixed right. Bet you feel pretty good about that. Well done.
