## 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.

*by J***L on 18 September 2024*

Using Loctite spray on cleaner primer with this product, guarantees leak free stainless steel pipe connections. After applying the sealer to primed pipe threads, this thread sealer begins setting up within 5 minutes. Polypropylene Glycol coolant defied all attempt at sealing stainless steel pipe connections until I cleaned the pipe threads, applied Loctite Primer, allowed it to dry, then applied a coat of Loctite Liquid thread sealer. No coolant leaks when using this thread sealer on pre-primed connections. I recommend this product for stainless steel, brass, and Iron pipe connections.
