Rislone Hy-per Cool Cleaner & Super Flush, 11.5 oz, Pack of 4

**Editorial Review of Rislone Hy-per Cool Cleaner & Super Flush** The Rislone Hy-per Cool Cleaner & Super Flush has garnered a mixed reception from customers who have sought to rejuvenate their vehicle’s cooling systems. Many users have reported favorable outcomes, particularly when using the product to eliminate longstanding grime and contaminants within older systems. For instance, one review highlights a successful flush of a 180K mile Ford radiator, noting that the coolant system remained free of overheating issues after treatment. Customers appreciated the product’s ability to extract black particles that water alone could not remove, providing reassurance of its effectiveness. However, while the majority of feedback is positive, there are a few notable concerns. One user reported damaging their radiator while using this product, suggesting a lack of compatibility or issues with older systems. Additionally, while some users saw a marked improvement in engine temperature after using the rinse, others, particularly with very old components like a 37-year-old heater core, did not note any significant difference in performance. Overall, Rislone Hy-per Cool Cleaner & Super Flush is regarded as a robust solution for cleaning and flushing radiator systems, especially effective in clearing out gunk and debris. However, potential users should exercise caution, particularly in older vehicles with pre-existing issues, to ensure that the product aligns with their needs. **
