So my engine did not have this, and while ordering my motor mounts, noticed them for sale. I bought the heat valve spring as well as the anti-rattle spring. My question is do they both go onto the end of the flapper, or is the anti-rattle spring even needed. i could only get one spring on, so i only replaced one. A photo would be awesome. or any advice. The shop manual wasn't much help. I may be overthinking a very simple item, but just wanted to double check.
