engine FORD SIERRA 1990 2.G XR4 Workshop Manual

Introduction0 1
BAT BATBAT BAT
BAT is pleased to be able to offer this line of components
for the U.S. specification "Merkur" XR4ti, Scorpio and the
other European models of Sierra lineage. European Sierra
models have been manufactured since 1982 and include
two versions or body styles. We will concern ourselves with
the Mark 1 as it is more similar to our U.S. version. The high
water marks of the MK1 series are the XR4i and the Sierra
Cosworth and R/S 500 models. From the exterior, XR4i is
very similar to the U.S. Merkur XR4Ti in overall looks.
However, under the hood it is powered by a 2.8L V-6 engine
where we have the 2.3L 4 cylinder turbo. The other notable
MK1 car the Cosworth Sierra is simply one of the more
outrageous vehicles Ford has ever offered. The Cosworth
starts life as a base Sierra three door body shell and adds a
high performance engine, suspension, transmission, and
aerodynamics, making it one of the fastest 4 passenger road
cars in the world. Power comes from a 2.0L Cosworth Turbo
YB series engine rated at 205 h.p. in its base form, and
upwards of 550 h.p. in modified rally form. The R/S500
homologation outgrowth of the R/S Cosworth version is
basically a de-tuned race car in street trim. Sierra MK2
versions received a sheet metal make over but share most of the mechanicals of the MK1. Interesting MK2
Sierra's include the Sierra Sapphire Cosworth, and Sierra XR 4x4 - an advanced 4 wheel drive 4 door sedan.
What all this Sierra history means to us is an abundance of specialized
performance parts, many of which bolt-on to our U.S. spec. Merkur. With
this in mind Merkur owners can make an good vehicle even better. It is
very amusing how much attention a Merkur that has been outfitted with
Ford badges and Sierra logos and Cosworth grille commands, let alone
a car equipped with the complete Cosworth body work!

Suspension Packages -XR4
Below is a listing of shock and spring packages available as engineered
suspension packages. Fixed rate or adjustable shocks are supplied as noted.
More information on the shocks that make up these kits is listed elsewhere in
the front and rear suspension sections. Kits are available with either -25mm
or standard ride height sport springs- your choice same price !
Spax Sport Gas Shocks & Sport Springs (-25mm or Standard) M400S
* supplied with fixed rate high performance gas shocks
Bilstein Gas Shocks & Sport Springs (-25mm or Standard) M400B
* supplied with fixed rate high performance gas shocks
Spax Sport Adjust Shocks & Sport Springs (-25mm or Std.) M400A
* supplied with adjustable high performance gas shocks
pB Sport Spring Sets -XR4
Our specially designed progressive rate sport springs will minimize body "roll" while
cornering and reduce "dive" under hard braking. Progressive springs are designed to
become stiffer as they are compressed allowing for a smooth transition between (very
reasonable) straight line comfort and high performance cornering. We recommend
the standard height or -25mm ride height sets for all around performance street and
light competition use, the -40mm springs should be considered for only racing/
competition use. Take into account when lowering your cars ride height that additional
negative camber will be added to the front and rear suspension angles. This is usually
not a problem on the front end, however, cars that are already experiencing noticeable
wear on the inside edges of the rear tires at "standard" ride height will see this increase
when lowering. This condition can be corrected if necessary by using camber shims
(kit available below) at the rear spindle mount to adjust for excessive negative camber.
Notes: Defining "standard" ride height is difficult on the XR4 as the springs on many
cars have already "sagged" 1/2 to 3/4 of an inch since new. In this case if the front
and rear tires are still wearing normally lowering the car another 1/4" or 1/2" (over what
it is currently) should not adversely effect tire wear.

See Price List For Scorpio Spring Applications
pC Rear Camber Shim Kit -XR4
To correct rear camber angles on cars that have excessive negative camber
we offer a handy rear spindle shim kit. This kit is sometimes necessary on cars
with lowered sport springs, but can also be used to correct camber on cars with
"sagging" stock rear springs. The components (instructions and shims)
needed to space the rear bearing spindles between the brake backing plates
are supplied. This camber kit will add roughly 1.5 degrees of positive camber
and adjust rear toe back with in standard range as well.M423R
pD
Front Strut Tower Brace -XR4
The XR4 has a well built chassis structure that does not exhibit much flex
under normal conditions. With the addition of high performance tires and
suspension parts more stress is put on the front strut towers causing some
deflection under hard cornering which will eventually weaken the structure
and lead to unpredictable handling characteristics. Connecting the front strut
towers by adding a upper stressbar (strut tie bar) will improve chassis
stiffness and keep the suspension angles constant under hard use condi-
tions. For this purpose we offer a lightweight aluminum front tower brace
(stressbar) that incorporates a removable tubular cross brace and cast alloy
turret mounts. Highly recommended for cars that are used for track events,
drivers schools, auto-cross and spirited road use.M403F
pE
Rear Shock Mount Brace XR4
Our rear (stressbar) is a nicely finished lightweight tubular aluminum rear
brace which is just the thing for linking left and right hand upper shock mounts.
A slight bit of plastic trimming is required when fitting. Bars are supplied with
an attractive blue finish.M403R

Racing Brake Fluid Not all brake fluid is created equally. High
operating temperatures at the caliper transfers extreme heat through the piston
causing lesser quality brake fluid to boil. This in turn allows the fluid to become
compressed and reduces overall braking performance. The best way to
counter this from happening is to use a racing specification, mineral (never
synthetic) brake fluid and flush the system after each event for competition or
annually on performance street driven vehicles. Both AP550 and Wilwood 570
brake fluid is DOT approved with a dry boiling point of 550-570 degrees, low
viscosity minimizes aeration and permits easy bleeding.

Cosworth & Scorpio Rotors For those fortunate few who own
Cosworth Sierras or have converted XR4's to Cosworth type front or rear brakes
and are in need of replacement rotors we have them. Scorpio front or rear rotors
in standard and cross drilled are also available. (see price list page 31)
Cosworth Front 283 x 24mm standard, X-drilled, grooved
Cosworth Rear 273 x 10mm standard, X-drilled, grooved
Scorpio Front 260 x 24mm standard or X-drilled
Scorpio Rear 253 x 10mm standard or X-drilled
Performance Brake Kits Engineered competition brake kits for the
ultimate in stopping power.
pC Front R/S Brake Kit (283 x 24mm)
BAT R/S "big brake" kit allows larger 11.25" (285mm) brake rotors to be fitted
with standard XR calipers. Increasing rotor "swept area" in this way will greatly
improve stopping power (leverage) and help to reduce high brake temperatures
that can cause premature brake fade and poor pedal feel.
Kit includes:
285 x 24mm vented (standard or cross-drilled) rotors, Mintex 1144 brake pad
set, caliper mounting brackets & hardware (fitment with most 15" wheels -
some require slight modification)

pA Constant Velocity Joints & Boots The Merkur XR4Ti and Scorpio
independent rear axle assemblys utilize half shafts that have inner and outer constant
velocity joints. Eventually these joints and protective boots will require service. We
have joints and boots available separately making it economical to replace just the
worn component without having to replace whole axle assembly. However, if more
than one C.V. per axle requires service, our complete axle assembly is the more cost
effictive way to go.
Note: right/left inboard and outboard C.V. joints and boots are
interchangeable- see price list for complete axle prices (handed left & right)

Rubber Drive Shaft Coupling The rubber "Drive Donut" or "Rotoflex
Coupling" on the XR4 and Scorpio drive shaft can be a real bugger. Many owners
have contacted us after being quoted up to 500.00 to totally replace the complete
drive shaft assembly by the local Ford L/M dealer, as they do NOT list the rubber
drive coupling as a separate service part. We import the proper replacement
drive coupling and make it available at considerable savings to you. If your car
exhibits a driveline shudder that increases with speed, (especially noticeable in
colder weather) we recommend taking a close look at the condition of the drive
coupling. Cracks in the rubber or missing pieces will require immediate replace-
ment, loosing one of these joints at speed will be very messy !
Note: BAT supplies
the standard equipment XR4i drive coupling by the original supplier to Ford. This
is not a lesser "fits all" component that just happens to be similar.

Quaife Torque Biasing Differential Quaife torque biasing
differentials provide a constant and infinitely variable output to both rear
wheels. These unique differentials utilize a series of helical gears which
sense the amount of applied torque and adjust automatically for loss of
traction. The Quaife limited slip design is also free of high wear items
(clutches, ratchets and plates), making them stronger and more maintenance
free than other types of limited slip units. Anyone who has had the pleasure
of driving a vehicle equipped with a Quaife LSD will immediately comment on
its smooth seamless performance, very unlike clutch/plate type LSD's which
exhibit a notchy ratchet like take up through the drive line. The Quaife LSD
that we offer is originally designed as a replacement upgrade for the Sierra
Cosworth and are now supplied with output flanges tapped for either the large
108mm (Cosworth size) or smaller 100mm (XR4 size) C.V. joints.

Clutch Kits We have a very good selection of clutch packages that include
clutch disk, pressure plate, throw out bearing, and clutch alignment tools. Buying one
of our engineered kits will guarantee best quality, performance, fitment (ease of
installation) and price. First option is a new (not rebuilt or re-lined) O.E. quality
replacement clutch kit by Sachs/Valeo. This clutch is best suited for standard or
slightly modified cars being used under normal driving conditions. If your requirements
are beyond the capabilities of the standard clutch we also have some heavy duty clutch
kit options. H.D. clutch kits include pressure plates that have increased clamping force
(from 30 to 50%) and clutch disks with high temperature friction materials applied.
Centerforce H.D. clutch kits have a unique centrifugal pressure plate design with
substantially more clamping force but requires very little pedal pressure over the stock
clutch.
Note: all kits are for standard transmission 1" 23 spline except where noted.

Cosworth Front Grille Nothing transforms the look of the XR4Ti quite like
adding a Cosworth grille. Designed with a center opening, the Cosworth grille
adds additional air flow to the radiator and A/C condenser for a cooler running
engine and better air conditioning performance. An intercooler could also be fitted
behind the grille opening as is done on the original Cosworth Sierra and R/S 500
models.
Note: Grilles are O.E. quality (injection moulded plastic) not shoddy fiberglass
replicas. Suppled (primed) un-painted- includes "Ford" emblem

and can also be fitted to standard Merkur XR4Ti fenders by drilling a mounting
hole. Kit includes (2) lamps, wiring and templates.M317
pL
Cosworth Hood Original equipment Ford Sierra Cosworth hoods are
designed to receive hood vents/louvers for additional under hood cooling. These
hoods look quite distinctive as the raised center section is lower and wider than
on the standard XR4 hood giving the car a more aggressive appearance.M813
pM
Cosworth Hood Vents Hood louvers/vents are both visually striking and
functional as they help to ventilate the engine compartment. These O.E. Ford vents
(pair) bolt into the Cosworth hood (above) or can be fitted to standard hoods by cutting
a hole and bonding them in place.

Cosworth Front Spoiler/Bumper We supply everything required to
install the stunningly attractive Cosworth Sierra front spoiler/bumper to your
XR4Ti. All components are original Ford including; bumper, bumper bar
brackets, lower side fender mounting panels, fog lamps, turn signal lamps, and
assorted hardware (clips & fasteners).
Note: bumpers are supplied in white-
can be painted to match other colors.

Cooling System (Scorpio)
In addition to our stock of cooling system components for the XR4Ti
we have added the various Scorpio related items to our inventory.
The Scorpio's cooling system is only slightly less complicated than
the XR4Ti's, it's only saving grace is the parts do not vary all that
much from year to year. Again, as with the XR4, components that
we offer are from the O.E. supplier or Ford originals.

Intercooler Kit If you are looking for a large high flow
intercooler kit this is the one to have. Intercooler core mounts
ahead of the steering rack in front of the engine facing the
ground. Air is ducted up and through the core. Plumbing is kept
short and allows for a larger core than what can usually be fitted
in the bumper/grille area. Kit is complete with intercooler core
(8" x 20" x 3.5"), mounting brackets, inlet plumbing pipes &
connectors, clamps, turbo output elbow, bypass valve and
additional hardware and instructions.

Exhaust Components We offer the Modern Performance line of
exhaust related items for the XR4Ti including full systems (hi-flow down pipe,
converter and muffler) as well as cat back systems (excludes converter).
Exhaust piping and mufflers are constructed in heavy 14 gauge aluminized
tubing, converters and mufflers are straight through design for minimum
restriction. These systems are unparalleled for performance and sound great
too. The 3" down pipe can be added to standard or
Borla systems for increased
performance. We also stock the standard Ford cast iron exhaust manifolds
(which are prone to cracking) or alternate stainless tubular exhaust headers.
