Product Condition Grades
Below is a general description of what the criteria is for our product condition grades. These are generalizations that are intended to give you an idea of the condition of the product at a quick glance. Because different parts degrade at different rates, there are variances in what the letters represent, please see the products description for details about the condition of any particular product.
A = Excellent / Above Average
B = Average / Some flaws / Good to Excellent Driver Quality
C = Obvious flaws / Poor to Average Driver Quality
D, E, F = Worse, Worser, Worsest
Used aluminum water neck of thermostat housing for most 1967-70 Mercury Cougar or most other Fords with 390/427/428CJ engines. Cast aluminum finish. Comes with threaded hole for either a screw-in cap, or thermal switch. For use with common 2-1/8 inch thermostats. Correct for 1968-70 FE engines. Not going to lie, these will show some signs of electrolysis on the inside and where the hose slips on. Additionally, we notice that the threads get a bit rotted out where the thermal switch resides.
*Note - very early 1967 cars were still using the 2-1/2 inch thermostats. Cutoff was around November 1966.
