Is there something that can be used to patch a fan shroud? Mine broke off when backed into a while back. The shroud still mounts and is mostly there, but the 90% of the top of the shroud has a 1/2 gap (because the plastic broke) between it and the radiator. I'm guessing this is partly the reason my temp goes to 90C when idling in hot weather (normal operating temp is 82C)
