IDLE MIXTURE
E2SE CARBURETORS
1. Remove the carburet or from the engine.
2. Remove the plugs coveri ng the idle mixture needles.
3. Turn the mixture needle in until slight ly seated, then back it out 4 turns.
4. If the plug in the air horn coveri ng the idle air bleed has been removed,
replace the air horn. If the plug is still in place, do not remove it.
5. Remove the vent stack screen a ssembly to gain access to the lean
mixture screw.
6. Using tool J-28696-10 or equivalent, turn the lean mixture screw in until
lightly seated, then back out 2
1/2 turns.
7. Install the carburetor on the engine.
8. Disconnect the bowl vent line at the carburetor.
9. Disconnect the EGR hos e and canister purge hose at the carburetor.
Cap the ports on t he carburetor.
10. Find the hose from port D of the carburetor to the temperature sensor
and secondary vacuum break thermal vacuum switch. Disconnect and
plug the vacuum hose going to the air cleaner.
11. Connect the positive lead of a dwell me ter to the mixture control solenoid
test lead (green connector). Connect the other lead to ground. Set the
meter to the 6 cylinder position.
12. Run the engine on the high step of the fast idle cam until the cooling fan
starts to cycle.
13. Run the engine at 3,0 00 rpm and adjust the lean mixture screw slowly.
Allow the reading to stabilize, obtain an average dwell of 35 degrees. It is
normal for the dwell to vary in a narrow range.
14. Return to idle.
15. Adjust the idle mixt ure screw to obtain an av erage dwell of 25 degrees.
Allow time for the reading to stabilize.
16. Run the engine at 3,000 rpm and not e the dwell reading. It should be
varying with an average reading of 35 degrees. If it does not, repeat the
earlier steps.

3. Clean all dirt from
the area around the cover. Re move the bolts retaining
the cover to the housing. Pry the co ver from the differential housing and
allow the fluid to drain into the catch pan.
To install: 4. With the cover and housing washed free of oil and gasket material, apply sealer to the mating surfaces.
5. Using a new gasket, install the cove r and torque the bolts to 20 ft. lbs.
(27 Nm) in a clockwise pattern to in sure uniform draw on the gasket. Fill
the differential with fluid through the fi ll plug and add limited slip additive,
as required.
6. Install the parking brake cable guides, if removed.
7. The fluid level shou ld reached a level within
3/8 in. (10mm) of the filler
plug hole. Replace the filler plug. Low er the car and inspect for leaks.
COOLING SYSTEM

CAUTION - When draining the c oolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is c ontaminated or several years old (in
which case it should be taken to a recycli ng facility such as a service station).
FLUID RECOMMENDATIONS
When adding or changing the fluid in the system, create a 50/50 mixture of high
quality ethylene glycol antifreeze and water.
LEVEL CHECK

Fig. 1: Fluid level marks on the cool ant recovery tank. With a warm system,
coolant level should be just below the FULL HOT mark on tank.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 795
Fill the cooling system wit
h a 50/50 mixture of water and Ethylene Glycol
antifreeze. Freezing protection should be appropriate for temperatures of -34°F
(-37°C). When filling the coolant system, add two cooling system sealer pellets
(GM part no. 3634621 or equivalent).
9. Firmly set the parking brake. Run t he engine with the radiator cap OFF,
until normal operating tem perature is reached.
CAUTION - Under some conditions, ethylene glycol is flammable. To avoid
being burned when adding engine coolant, do not spill it on the exhaust system
or on hot engine parts.
10. With the engine idlin g, add engine coolant to t he radiator until the level
reaches the bottom of t he radiator fill neck. Install the cap assembly.
When installing the cap, make sure t hat the arrows on the cap line up
with the overflow tube.
Never add cold water to an overheated engine.
11. Add coolant to the recovery tank, as necessary.
12. After filling the radiator and recovery tank, run the engine until it reaches
normal operating temperature, to ma ke sure that the thermostat has
opened and all the air is bled from the system.

FLUSHING AND CLEANING THE SYSTEM

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 797
The cooling system should be drained, th
oroughly flushed and refilled at least
every 30,000 miles or 24 months. This operation should be done with the \
engine cold.
1. Drain the cooling system as de scribed earlier in this section.
2. Fill the cooling system with warm water and start the engine. Run the
engine until normal operating temperature is reached.
3. At this point, turn the engine o ff and again drain the cooling system.
4. Repeat this procedure until the flui d draining from the system is nearly
colorless.
5. Remove, empty and reinstall the coolant recovery reservoir assembly.
6. Fill the cooling system with a 50/50 mixture of ethylene glycol antifreeze,
as outlined in the prev ious procedure.
BRAKE MASTER CYLINDER
FLUID RECOMMENDATIONS
When adding or replacing the brake fluid, always use a top quality fluid, such as
Delco Supreme II or equivalent DOT-3 flui d. DO NOT allow the master cylinder
reservoir to remain open for long periods of time; brake fluid absorbs moisture
from the air, reducing it s effectiveness and causing corrosion in the lines.
Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring cables
or electrical connections. Brake fl uid will damage paint and electrical
connections. If any fluid is spilled on t he vehicle, flush with water to lessen
damage.
LEVEL CHECK

Fig. 1: Check master cylinder fluid leve l against indicator on side of reservoir.
Fluid level should not be below MIN marking on reservoir.

9. Connect one end of the other jumper
cable to the negative (-) terminal on
the booster battery and the final cable clamp to an engine bolt head,
alternator bracket or ot her solid, metallic point on the engine with the
dead battery. Try to pick a ground on the engine that is positioned away
from the battery in order to minimi ze the possibility of the 2 clamps
touching should one l oosen during the procedure. DO NOT connect this
clamp to the negative (-) term inal of the bad battery.
CAUTION - Be very careful to keep the jum per cables away from moving parts
(cooling fan, belts, etc.) on both engines.
10. Check to make sure that the c ables are routed away from any moving
parts, then start the d onor vehicle's engine. Run the engine at moderate
speed for several minutes to allow the dead battery a chance to receive
some initial charge.
11. With the donor vehicle's engine still r unning slightly above idle, try to start
the vehicle with the dead battery. Crank the engine for no more than 10 \
seconds at a time and let the starter cool for at least 20 seconds between
tries. If the vehicl e does not start in 3 tries, it is likely that something else
is also wrong or that the battery needs additional time to charge.
12. Once the vehicle is star ted, allow it to run at idle for a few seconds to
make sure that it is operating properly.
13. Turn ON the headlight s, heater blower and, if equipped, the rear
defroster of both vehicles in order to reduce the severity of voltage spikes
and subsequent risk of dam age to the vehicles' electrical systems when
the cables are disconnected. This st ep is especially important to any
vehicle equipped with computer control modules.
14. Carefully disconnect the cables in the reverse order of connection. Star\
t with the negative cable that is attached to the engine ground, then the
negative cable on the donor battery. Di sconnect the positive cable from
the donor battery and finally, disconnect the positive cable from the
formerly dead battery. Be careful when disconnecting the cables from the
positive terminals not to allow the alli gator clips to touch any metal on
either vehicle or a short and sparks will occur.
JACKING
Your vehicle was supplied with a jack for emergency road repairs. This jack is
fine for changing a flat tire or other s hort term procedures not requiring you to
go beneath the vehicle. If it is used in an emergency situation, carefully follow
the instructions provided eit her with the jack or in your owner's manual. Do not
attempt to use the jack on any portions of the vehicle other than specified by the
vehicle manufacturer. Always block the diagonally opposite wheel when using a
jack.
A more convenient way of jacking is the use of a garage or floor jack. You may
use the floor jack to raise the vehicle in the areas shown in the illustration .
