2006 Mercury Montego engine

If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
•First, at least 10 minutes of driving on an expressway or highway.
•Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
POWER STEERING FLUID
Refer to thescheduled maintenance informationfor the service
interval schedules. If adding fluid is necessary, use only MERCONAT F.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.

If your transaxle does not engage normally, do not attempt to
drive. The vehicle should be towed to your authorized dealer for
evaluation.
Checking 6–speed automatic transmission fluid (if equipped)
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transaxle does not consume
fluid. However, the fluid level should be checked if the transaxle is not
working properly, i.e., if the transaxle slips or shifts slowly or if you
notice some sign of fluid leakage.
Checking automatic transmission fluid at operating temperature
(158°F-176°F [70°C-80°C])
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the vehicle should be
turned off for about 30 minutes to allow fluid to cool before
checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect
the fluid level. The fluid should read
within the hot range on the dipstick
if at normal operating temperature
(158°F-176°F [70°C-80°C]).

If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause
shift and/or engagement concerns and/or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.

The PCV valve is a critical emission component. It is one of the items
listed in thescheduled maintenance informationand is essential to
the life and performance of your vehicle and to its emissions system.
For PCV valve replacement, see your authorized dealer. Refer to
scheduled maintenance informationfor the appropriate intervals for
changing the PCV valve.
Replace the PCV valve with one that meets Ford material and
design specifications for your vehicle, such as a Motorcraft or
equivalent replacement part. The customer warranty may be void
for any damage to the emissions system if such a PCV valve is not
used.
2For spark plug replacement, see your authorized dealer. Refer to
scheduled maintenance informationfor the appropriate intervals for
changing the spark plugs.
Replace the spark plugs with ones that meet Ford material and
design specifications for your vehicle, such as Motorcraft or
equivalent replacement parts. The customer warranty may be
void for any damage to the engine if such spark plugs are not
used.
