As part of this project I am replacing a lot of the cooling system hoses that I have reasonable suspicion of being over 10 years old. Unfortunately, it appears PN 6421838353 (HOSE F ENGINE INLET AND WATER VALVE) is NLA. Both ECS and the dealership cancelled my orders. Not seeing an aftermarket alternative too. The hose that I currently have is by Corteco and appears to be in good condition.
