Will timing belt on Honda Ridgeline cause engine damage?

Yes, if the timing belt on a Honda Ridgeline fails, it can cause significant engine damage. Unlike some engines that have a non-interference design, Honda engines typically have an interference design, meaning that if the timing belt breaks, the pistons can collide with the valves. This can lead to bent valves, damaged pistons, and extensive repair costs. Therefore, it's crucial to replace the timing belt at the recommended intervals to prevent such issues.
