Brand-new billet aluminum water outlet (thermostat housing) with FREE GASKET for 1986-1987 Buick Grand National, Turbo Regal, 1987 GNX and 1989 Turbo Trans Am. This listing is for the water outlet (thermostat housing) ONLY. (the photos in this listing show the aluminum intake manifold for reference purposes only. The aluminum intake manifold shown in these pictures is NOT included)
This is an exact replacement part that we have test fit in our facility and comes complete with a FREE brand-new O-ring gasket as shown in picture.
Most importantly, this Highway Stars water outlet is made of ALUMINUM, because aluminum will NOT cause electrolytic corrosion of your irreplaceable aluminum intake manifold.
Another better value on a much better product from Highway Stars.
Caution: Stainless steel versions sold elsewhere will promote electrolytic corrosion when used with an aluminum intake manifold (caused by dissimilar metals)
