Product Description
Brand-new Highway Stars reproduction LC2 Turbo Wastegate Hose Assembly for 1986-1987 Buick Grand National, Turbo Regal, 1987 GNX and 1989 Turbo Trans Am.
This turbo wastegate hose assembly consists of 4 exact length, proper diameter molded (5/32" & 7/32") vacuum hoses with special flow restrictor tee and reducing elbow. This assembly interconnects the turbo outlet (boost) side with the turbo wastegate actuator and turbo wastegate solenoid for proper turbo boost control.
Due to the effects of aging and heat, it is common to find factory original 37+ year old wastegate hose assemblies that have deteriorated and "dry-rotted".
Deteriorated hoses will leak and cause erratic turbo boost.
Original hoses should all be inspected and checked for integrity.
