This is for an Acura MDX btw. Manual states to not do a complete flush. Just drain and refill.

If he has a 'slow leak', check the cap and make sure it holds pressure. After a couple of 3 years, the caps give out, causing a 'slow leak'. It's not really leaking, it's just filling the overflow tank and dumping it on the ground.
