GM ( Chevrolet or GMC ) 4.3 L V6 Engine Tear Down
This video goes through the teardown process of a GM 4.3L V6. It has been
removed from the vehicle and we take it apart, except for crank and piston
The automobile consist of:
• 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.

To the best of my knowledge this video is accurate. I am in no way

Special thanks for the mention from my frineds in Iowa Sofia and Baloushka

I've enjoyed watching thier videos and watching them get thier daily vlogs
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.

GM 4.3L V6 / 5.7L V8 - Fuel Spider Swap, SCPI to MPFI
Video of me swapping the fuel spider out of my vortec after it failed.
All the tools and tricks needed for the job are outlined in the video.
5/8'' Crows foot will be your best friend.
here were the symptoms:
Truck would start rough and require throttle to even out when warm. Would
usually cold start fine. This lasted for about 6 months, then it got to
where it would be so flooded it would run like shit and not even out. fuel
pressure regulator was dumping fuel out of itself and into the upper
intake; whenever the fuel pump turned off. I demonstrated this in the video
with the plenum off and the injectors plugged in.

If your have a pre-2003 4.3L I highly recommend you replace your poppets
with the new multi port spider. Just about the best upgrade you could do.
Changed the plugs and wires as well and now get 19mpg (up from 16 with the

How To Perform a Compression Test - EricTheCarGuy
Compression Testing and What You Can Learn From It - EricTheCarGuy
Here is a video on performing a compression test on an engine to assess
it's mechanical condition. An engines ability to compress air and fuel is
directly proportional to it's performance since an engine is nothing more
than an air compressor once you take away all the controls. A compression
test is a good general test that will give you an idea of the engine's
overall health but it does not give specific information on what the
problem is should there be one, for that a "leak down test" would be
required, here is a link to that video.
However if you find yourself looking for the source of a performance
problem with an engine, this is a great place to start. This test is often
overlooked in favor of looking at the fuel or ignition system, I think
that's a mistake, if an engine can't perform mechanically no amount of
electronics will make that better.
Recently, I hit the 500 subscriber mark and I'd like to thank all of my
subscribers past, present, and hopefully in the future for that. I enjoy
making these videos and the fact that you seem to like watching them means
a lot to me. So, thanks for subscribing, rating, and commenting, those
little contributions make it all worth while.
