If this is for one of your 4wd vans then there's nothing available (not even aftermarket). Some parts sites may still list it but I'm guessing it will come back as NLA when you place the order. Like coronan says, when you have an issue with a radiator pull it out and take it to a radiator shop. They are the experts and if it can be fixed they will fix it. Never a good idea to put epoxy or anything else on a radiator, but I'm guessing it won't stick good enough to create a problem anyhow (probably come right off when they mess with it). Tim
