## Questions & Answers

**Q: is loctite 577 or 567 better for engine coolant fittings on an automobile engine to prevent leaking?**
A: I have only used the 577 on a boiler heating system which contained a 50% solution of antifreeze.  So far it has been the only product that worked.  The 567 is similar to 577 but the 577 is better for coarse threads.

**Q: If possible, can you please provide me the manufacturing date and the expiration date of this product? I need Loctite 577 that has longer shelf life.**
A: This item has a shelf life of 2 years. Each item will have a manufacture batch code and you would need to contact Loctite directly in order to find out when it was manufactured.
