Check the union nut size FIRST, if the union nut is 3/4 or 19 millimeters they should fit. The nut and cap design must have the same head in order to be able to remove both. They fit my 2003 Pontiac Grand Prix exactly, but according to the auto parts store they don't fit. So if you have 7/8 nuts, you need 7/8 caps, not these. If you have 3/4 nuts they will fit.
