• Fuel System: Purpose is to deliver fuel to the engine. It consists of
the fuel tank, pump, gauge/sensor, filter, pressure regulator and
• Air Intake System: Purpose is to clean and direct outside air into the
engine. It consist of air filter, ducts, air plenum and intake manifold.
• Exhaust System: Purpose is to
direct Exhaust gasses out of
combustion out of engine. It consists of the Exhaust manifold, converters, pipes and
• Cooling System: Purpose is to remove excess heat from the engine. It
consists of water pump, hoses, radiator, thermostat, cooling fan and
coolant recovery tank. Also the oil system serves as a cooling system as
well as a lubricating system. It consist of oil pump, pan, filter and
1. Clutch: Purpose is to connect the engine and transmission together. It
consists of clutch drive disc, driven disc, release bearing, clutch fork,
cable, slave cylinder, master cylinder. There are three types of clutch
systems: mechanical, cable and hydraulic.
2. Transmission: Purpose is to match engine speed to road speed. Two types
used are manual or automatic. These consist of gears, linkages, cables and
converters for automatics. A manual is connected to the clutch by a
flywheel and automatic by a flexplate.
3. Driveshaft: Purpose is to connect the transmission to the rear axle. It
consists of a slip yoke, shaft and universal joints.
4. Rear axle differential: Purpose is to change the angle of motion from
engine to the wheels. It also divides torque between the wheels. It
consists of a ring and pinion gear, carrier, bearings, crush sleeve and
5. Wheels/Tires: Purpose is to provide traction to the road as well as
carry the weight of the vehicle.
Vehicle Control Systems:
1. Brakes: Purpose is to slow and stop the vehicle. It consists of master
cylinder, brake Booster (vacuum or
hydraulic), calipers, drums, pads and rotors.
2. Steering: Purpose is to direct vehicle in the required direction.
Consists of steering gear (rack & pinion), steering wheel, column,
inner/outer tie rods, pump, reservoir, hoses and pipes.
3. Suspension: Purpose is to provide stability and handling while also
providing comfort to the ride. Consists of shocks, struts, sway bars, end
links, springs, trailing arms and bushings.
1: Heating Ventilation Air Conditioning (HVAC): Heats and cools interior
air to passenger comfort. Also circulates outside and inside air.
• Air Conditioning: Consist of condenser, compressor, accumulator
(receiver/dryer) orifice, expansion valve, hoses, evaporator, controls,
actuators and modules.
• Heating: Consists of heater core, valves, hoses and switches.
1. Power Generation: Creates electrical power to run all the electrical
systems. Consists of the alternator.
2. Power storage: Stores unused power to start the car and supply voltage
to the alternator to create more electricity.
• Both systems consist of wiring, harnesses, fuse, relays and modules
98 S10 Vortec V6 4.3 Intake Gasket Replacement Part 1 of 5
Well I think I have a bad intake gasket on the drivers side. I had a small
coolant leak coming from the water pump but now I have a pretty bad leak
that is getting on the Exhaust
manifold on the drivers side. Going to take it off and have a look. From
what I have seen online intake gaskets are a pretty common thing on the 4.3
and 5.7 vortec engines. I will try to be as detailed as I can to help
others doing this same job.

A detailed description for beginners. Also included in the video is a
torque sequence diagram.
To the best of my knowledge this video is accurate. I am in no way
responsible for any occurrence resulting from following the instructions in

This video is of the inside of the 4.3 litre V6 motor i am in process of
putting in my daughter's 1997 Chevrolet S-10 Blazer i don't explain it
well and the 4 strokes of the motor i couldn't remember are as follows,
Intake, compression, ignition and Exhaust. hope you enjoy my fumbled explanation.
Fuel pressure regulator repair blazer bravada jimmy s10 sonoma 4.3l
if the fuel pressure regulater is leaking in yours replace it, change the
oil right after. if it was leaking bad then there will be gas in the
crankcase oil. and WILL cause rod bearing failure if not caught in time.
over time the gas will leak down the intake passages and into the
combustion chamber leaking past the piston rings then into the oil.
