1986-87 Buick Grand National Oil cooler lines. Now reproduced to freshen the engine bay back up. Replaces GM part #25530418 25530419.
This is a must when you get your engine rebuilt. Debris and metal shavings can be transported thru the lines and get stuck into the rubber hose once hot. If reused they can break loose at any time. They will travel through the radiator. If not trapped in the filter screen or even if it is, they will go back thru the radiator and back into your rebuilt engine.
The lines have the cloth style outer covering just like the 1986 and early 87 Grand Nationals and Turbo Buicks. The fittings are steel and the lines come with new O rings.
The new lines are pictured on top. The originals are below.
