Had to yank out a NAPA/Gates lower radiator hose for an OEM hose on an 04 Lexus LS430 because it started to rub on the power steering pump pulley and spew coolant. Initial installation looked like it would clear the pulley with 1/2" clearance but as the hose warms up it began to expand and flex and it would begin to rub on the pulley. Before that at the parts store I compared the original hoses to the new hoses. I knew it looked sketchy that it didn't bend enough for more clearance around the pulley area. I chanced it since I've used aftermarket hoses on BMW's and Mercs with no issues and it was cheap for the pair of upper and lower hoses. Lexus dealership had the hoses and swapped it over the same day.
