yes i know my radiator was very rusty because i never cleaned it but the majority of crap that you see is stop leak im sure
the product i used looks like dirt and rust
i dont remember the name but i still remember what is look like
im very satisfied with the new radiator even with its cheap quality
now with 45°C outside i get 80°C with ac on in highway and 90°C in city
any ideas guys for cleaning the heater core? i dont want to freeze in winter
a friend told me to use HCL
