    • Perfect on my 2010 tahoe!
Size: 5/8 10FT

Update: hoses already have1k miles on them and zero leaks and performing as expected! Evil Energy holding up! I recently had a coolant leak on my 2010 tahoe right on the heater T connectors that are by the firewall that lead to the heater core, very common on these vehicles due to the original connectors being plastic so i decided to change them with Dorman metal ones. I also decided to change the hoses too since mines looked pretty old and came across this one. Im not new to evil energy so i didn’t hesitate. This hose while it has the same ID 5/8 as the old ones, is thicker, fits perfectly and feels stronger and like it will last much more than the old ones did! ... show more
