This cap began leaking coolant shortly after it was installed. I began thinking it was a head gasket issue or the overflow lines, but after much frustration, I traced the problem back to the cap. After replacing it with the stock unit, the problem immediately disappeared and the smell of burning coolant after each drive is gone. As always, customer service at RSD was quick to remedy the problem and their support is to notch. I always assumed coswortth was a byword for quality, but in this case I was disappointed
