Tech Center: Q & A with Dick Hertzler
I
have a 1968 XR-7. The drivers side door glass drops about 1 inch everytime
I shut the door. Could the regulator be shot?
You
hit it right on the head! Your regulator is faulty. Either the spring is
broken or the gear teeth are worn so far that they do not grip. I bet it
also doesnt catch evenly when you crank the window up. This is a common
problem and easy to fix with a replacement regulator. Check any Cougar vendor
for a good used one.
I
recently purchased a 69 hardtop with a 351-2V Windsor and among many strange
things Ive found under the hood (like the broom handle in the firewall)
is a loose kick down rod. This is absolutely not going to attach where I
think it shouldthe bracket I made didnt quite cut itand Chiltons makes no
sense. Can you point me in the right direction?
The
kickdown rod to the FMX transmission connects to a stud that attaches to
the throttle shaft and lever assembly, just next to where the accelerator
cable attaches. The stud often is missing on stick shift carburetors and
many rebuilt units. Its one of the parts you have to move over from the
old carb if you do a swap. You can see the complete kickdown rod illustration
and adjustment procedure in the 69 shop manual, page 10-09-03.
My
1968 Cougar is equipped with the factory option door edge guards (originally
a $4.90 option). Should these match the color of the interior or the vinyl
roof? I have talked to a few people about these moldings and nobody has
heard of them before. My moldings are faded from the sun and I cannot tell
if they were originally white to match the roof, or saddle to match the
interior.
The
door edge guards are chromed plastic. When they fade or the chrome plating
flakes off, you have only the plastic below, which is kind of a neutral
color. I will buy all the sets of these you can provide at $4.90! Expect
to pay $50 or more from any vendor who has them. Suggestion: If your guards
are basically in good shape, gently pry them off. Clean them, sand them
with fine paper and re-spray using the reflective aluminum paint (part number
10005Z) and clear coat (10197Z) from Eastwood Co. (800-345-1178). Be sure
they know you are spraying plastic.
I
need to unhook the vacuum headlight feed from the carburetor of my 1970
Cougar. Its leaking and causing really ugly running. Where is it on the
carb? Is this an easy thing to do?
Headlight
vacuum comes from a manifold tee behind the carburetor. Make sure you cap
the port to which the headlight feed is connected. By the way, make sure
your leak is not at this tee; the rubber cap on the downward-pointing connection
sometimes melts and leaks. Your headlight leak most likely is in the reservoir
tank under the fender.
Im
having a problem with a 70 Cougar. We went through the transmission when
we restored this car and installed a rebuilt torque converter. It now leaks,
but only after sitting idle for several days. Any ideas on the source of
the leak?
A
local Ford service manager suggests you check for a damaged or missing O-ring
seal where the transmission fill tube meets the case. He says the torque
converter is leaking down (probably the result of a bad seal) and filling
the pan to the point that you get leakage out of the fill tube connection.
One clue to this problem is a brief delay before the transmission engages
after the car has sat idle for a few days, a result of too little fluid
in the converter (but the dip-stick will show full due to the leak down).
I
have a 1996 Cougar. It has a factory keyless entry system and a dealer installed
Ford Vehicle Security System. After a recent battery change, the security
system lost its settings. The alarm sets itself every time the ignition
is turned off. Before, the alarm set whenever the doors were locked either
by the keyless remote or the power door lock switch. I have no manual for
programming and the local dealership is no help. All I want is to set the
alarm when I want to. Can you help me?
I
also have the Vehicle Security System with Keyless Entry on my 92 25th Anniversary
car. Ive had similar problems and learned that Ford maintains a special
help line (800-FORD-KEY) with a menu prompt for owners with keyless entry
or vehicle security system. Give this a try.
Odds n Ends
n We had
a recent question about the dash turn signal indicators not going out, and
I explained just how these work and what to look for in troubleshooting.
Just last week, I was cleaning the trunk of my 68 Hertz XR-7G after installing
new reverse lights and discovered that the emergency relay in the trunk
was no longer attached to the wheel well board that holds the sequential
turn signal motor and relay. Mounting of the emergency relay to this board
is essential for proper dash indicator operation. The black wire to the
ground comes from the harness to a ground on the relay bracket, but the
bracket must be attached to the stud on the relay board for the ground to
be correct for the relay. I re-attached the relay bracket to the stud and
the dash lights now blink brightly and go out completely in sequence with
the middle tail light! Be sure the middle light is firmly snapped into the
tail light assembly to make a good ground.
n One of the CCOAs best friends is long-time
member and GT Registrar Brett Irick, who owns (and drives often) one of
the only Concours-class cars we have: a white 67 390 GT. Brett is an engineer
with Ford, currently New Model Launch Manager, Panther Frame at the Dearborn
frame plant. The Panther Frame will get rack and pinion steering and is
being beefed up to handle the 2003 Mercury Marauder. Brett has been a great
help to me answering your questions and reminded me that +2 degrees caster
(a bit outside spec) gives best handling/road feel to big block cars on
radial tires. He also recommends the one-piece export brace, available from
most vendors, in lieu of the two standard shock tower braces. As to steering
gear, Brett recommends Rodes Restoration, in Galion, Ohio, (419-468-5182)
for rebuilt steering boxes, power steering cylinders and control valves.
He also recommends an annual check of steering box lubricant level and FoMoCos
C3AZ-19758-A lubricant. For wheel bearing grease, even on older vehicles,
Brett suggests E8TZ-19590-A 4X4 High Temp grease. And stick with DOT-3 brake
fluid (higher guaranteed boiling temperature, critical to the four-piston
disc brakes on the 67 Cougar), Brett advises. Changing the brake fluid every
three years is highly recommended. Thanks, Brett, for your attention to
the questions I forward to you!
