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

Great stuff can’t go wrong

Cleaned out a normal 180K mile Ford radiator & cooling system with original Ford Gold antifreeze in the system.Antifreeze was your typical SE region of US quality for Ford Gold at 180K. The deegas bottle was stained black but coolant looked well used but fairly clean. No over heating issues & no heater core issues.Drained system using drain in radiator, filled with water using water hose thru tank, cranked engine left drain open & water running. After clear water coming out of drain from system I filled & drained the system 3 different times with straight water & ran the engine to operating temp each time.With system having zero antifreeze, most oils & loose trash out system I then added the product.I followed instructions then I flushed system out with running water to see this product did remove some black particle in the system that water did not get out on its on. Plus done temperature test. Car did not have any heat problems.Temperature rose another 10° F coming out the vent. So in my area of NC that doesn't mean a lot but I've been in Minnesota in winter & 10° means a lot there.

Worked well + added the super cool after car indeed runs cooler

Worked well, i had a blown head gasket so there was oil in my coolant system and it got like 90% of it.

Blew my radiator! I do not recommend, and I want my money back.

Works good as it should

Used it to try and flush the heater core, didn't notice any difference but I can't blame the product because the original heater core is 37 years old. With a new ratator, seen very little crud when flushed.

Easy to use. I flushed and cleaned the cooling system on my Jeep and it runs cooler and the heater/ac works so much better.
