TCCBTS's goal is to reward our first-year interns/apprentices by expending their experiences so they can show off their skill while still going to school.

How? Easy we're going to create and develop several, Independent Commercial Businesses for the interns/apprentices to work before class or after class or both, and allowed to work on weekends and paid $15.00 dollars an hour. Now the interns/apprentices are not only earning real money, but learning on the job skill social by interacting with real customers asking for their experience and help.

Note: After engine has been removed from vehicle and engine has been disassembled

DO NOT REUSE:
• Cylinder head screws
• Flex plate torque converter screws/bolts
• Old piston pins
• O-Rings

Fly wheel screws, known by most inexperienced as bolts which are actually called screws, add a nut then it a bolt

The Vehicle discussed in this project is a 2002 Isuzu Trooper LS 3.5L V6 DOHC 5 Door-4 Wheel Drive

NOTE: Replace

• "All" O-Rings
• Air cleaner filters
• Timing belt
• "All" Questionable parts, NOTE: Any necessary repairs
• Spark plugs
• Coolant
• Power steering fluids
• Engine oil
• Oil filter
• Hoses
• Drive belts
• Transmission fluids
• Fasteners, use only exact part numbers
• Control lever assembly
• Air Conditioning refrigerant
• Compressor oil
• Tires

Step 1:After relieving the fuel system pressure. Disconnect the negative battery cable. Drain the engine coolant. Drain the engine oil. The engine will have
an additional ground cable connected from the engine to the frame; this can be disconnected later after components have been removed to give easier access to
the ground cable to be disconnected from the engine. (Drain the radiator coolant into a container to be environmentally legal and dispose in a safe manner, if a
backyard mechanic, keep coolant out of reach of animals.)

(The fuel pressure control valve mounted on the fuel rail maintains a pressure differential across the injectors under all operation conditions. It is accomplished by controlling the amount of fuel that is recirculated back to the fuel tank based on engine demand. Relieve the fuel pressure by connecting a fuel pressure gauge to the fuel pressure connection on the fuel rail.) Fuel pressure is (41-46 psi engine running. In order to reduce the risk of fire and personal injury, wrap a shop towel around the fuel pressure connection. The towel will absorb any fuel leakage that occurs during the connection of the fuel pressure gauge; dispose the shop towel in approved container when the task is finished. Disconnect the fuel pump relay and crank the engine to relieve the fuel pressure.

Step 2: Make alignment marks on engine hood and hinges before removal in order to return the hood to original position exactly, remove engine hood, replace the hood screws back in their original location on the hood hinge, (place fender cover on roof of vehicle, place hood on the top fender cover).

• Remove the air cleaner assembly
• Remove the intake air cleaner housing
• Remove the drive belt

Step 4: Remove the intake manifold cover, power brake booster hose and the quick-connect fitting cover, and then disconnect the fuel feed hose. always plug any fuel line, thread a screw into all disconnected fuel line and/or hoses and plug them so dirt will not enter the lines.

Step 5: Disconnect the evaporative emission canister hose. Remove the intake manifold bracket.

Step 6: Remove the engine wire harness connectors and the wire harness clamps from the cylinder head and intake manifold. Remove the four fuel injector
connectors.

Step 7: Disconnect the engine coolant temperature sensor connector, throttle body connector, and the Air/Fuel (A/F) sensor connector. These connectors
are connected to the wire harness

Step 8: Disconnect the manifold absolute pressure connector, rocker arm oil control solenoid connector, rocker arm oil pressure switch connector, and the
Crankshaft Position (CKP) sensor connector.

As each step is explained there will photo's included to help you understand each step, the photos will be include to help you follow along better.

This Trooper 3.5L blew a #2 rod bearing, the bearing just, causing the crankshaft to push the rod up the cylinder wall farther than designed for, this caused the
piston to band into the head, but did not damage the head. The engine had small metal particles throughout the entire engine system.

The engine had to be pulled and cleaned. there was damage to the crankshaft which had to be taken to a machine shop to be repaired, the cylinder wall were
measured and were anywhere from 0.003 to 0.005 so the block had to be bored, honed, and cleaned.

• 1. Good body
2. Good interior
• 3. Good engine

The Isuzu Trooper met two of the criteria's requirements

• 1. Excellent body
2. Excellent interior

So it was worth doing the rebuild.

Follow these steps to remove engine from vehicle:
