Doosan V158TI Marine Engine Spare Parts
The Doosan V158TI marine engine is a turbocharged and intercooled V8 diesel engine used in commercial marine propulsion applications.
Built around the Doosan V158 platform, the V158TI combines an eight-cylinder V-configuration with mechanical fuel injection, turbocharging and charge-air cooling. This makes it a practical heavy-duty engine for vessels that require strong output, reliable operation and straightforward serviceability.
For marine engineers, vessel operators and shipyards, one important point is that many V158TI engines have already been in service for many years.
During that time, parts such as:
- Fuel Injectors
- Injection Pump
- Turbocharger
- Intercooler
- Freshwater Pump
- Raw-Water Pump
- Heat Exchanger
- Starter Motor
- Alternator
- Cylinder Head Components
may already have been replaced, repaired or reconditioned.
For that reason, the safest method for identifying Doosan V158TI Marine Engine Spare Parts is:
Doosan V158TI + Engine Serial Number + Existing Part Number + Clear Photographs

For spare-parts identification, always prioritize the full engine model, engine serial number and identification from the currently installed component.
3. What Does “TI” Mean on the Doosan V158TI?
The TI designation indicates a turbocharged and intercooled configuration.
The simplified airflow is:
Air Filter → Turbocharger → Intercooler → Intake Manifold → Cylinders
The turbocharger compresses the intake air.
Compression increases air temperature.
The intercooler removes part of that heat before the air enters the cylinders.
This arrangement introduces additional components such as:
- Turbocharger
- Intercooler
- Charge-Air Cooler Core
- Charge-Air Pipes
- Charge-Air Hoses
- Turbocharger Oil Feed Components
- Turbocharger Oil Drain Components
- Cooling-Water Connections
- Intercooler Gaskets
- Turbocharger Gaskets
- Charge-Air Seals
- O-Rings
4. Why Is the Intercooler Important on the V158TI?
The intercooler directly affects the temperature of the intake air reaching the engine.
The process can be understood as:
Turbocharger Compresses Air → Air Becomes Hotter → Intercooler Removes Heat → Cooler Air Enters Cylinders
If intercooler efficiency deteriorates, possible symptoms can include:
- Reduced Engine Power
- Increased Black Smoke
- Poor Load Response
- Higher Exhaust Temperature
- Higher Charge-Air Temperature
- Increased Fuel Consumption
This is why the turbocharger and intercooler should often be considered together during troubleshooting.
