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
This option requires you to PRE-PAY a core charge of $50.
Used grade "B" headlight door actuator for your Mercury Cougar. This grade B actuator has been reconditioned with new seals but will still slowly leak down after time as not all of them will function as new after being reconditioned. These actuators are sold individually on an exchange basis or outright (for an additional core charge). One actuator actuates both headlight doors on the 69-70. This unit also comes with a 30 day warranty.
Ford part # C9WY-13A167-A.
*NOTE* These actuators are prone to failure in two common areas. The first being the small circular upper shaft seal. Often the reason this seal fails is that the "accordion" style dust boot that covers the shaft will fail. This causes contaminants to enter and work as an abrasive between the shaft and seal. When the shaft seal goes bad, you will find your headlights not rising very fast or not at all. Also, the internal diaphragm seal is sometimes prone to failure. If you use a vacuum tester on your bottom vacuum port and find it does not hold 5 inches of vacuum for prolonged periods of time, then this unit is most likely your problem.
If you continue to run your Cougar with this problem, you are running with a constant vacuum leak. This may cause confusion as to why your 1967-68 Cougar does not idle well, lacks performance, and or fails to achieve 19-21 mpg with a stock 289 or 302. The actuators may be a good place to start looking. Dyno tests consistently show a 5-7 HP increase after headlight vacuum leaks are repaired.
Do you want to replace those worn out actuators yourself or are you looking for some great information on your Cougar’s headlight vacuum system? Check out our videos below:
