About Oil Coolers
Our engines [b]do NOT[/b] come with provisions for oil coolers. We've always advised strongly against the use of oil coolers on the GY6, and we refuse to offer them on our engines. We've seen too many instances where a cooler line bolt vibrated loose, dumping all of the engine oil and causing a massive failure. [b]The perceived benefit isn't worth the risk.[/b] Oil coolers on the GY6 solve a problem that doesn't exist. Follow regular maintenance intervals, invest in a UNI Air filter (and keep it oiled), and your new engine will last many years. Coolers provide a false sense of longevity benefits, and the only proven result is the added risk of unexpected massive failure.
