Just make sure to have it flushed regularly, together when you do a tune-up. If your radiator's top part is made of plastic, there is a good chance it will develop cracks on the part where the plastic cover is welded into the metal top. If that happens and you're stuck in traffic, be prepared to deal with an overheating engine.
