The upgraded system ensures reliable cooling and fuel delivery for a high-performance build.
Getting the Engine Bay Ready
Before installing the supercharger, several steps are needed to clear space and prepare the engine bay. The car must be raised for better access, and the front bumper should be taken off. The coolant is drained by removing the 19mm radiator plug.
Parts like the radiator cover, coolant reservoir, and the upper and lower radiator hoses are removed. Detaching the fan shroud, AC condenser, and power steering reservoir makes more room for the new supercharger bracket and related components.
To-Do List:
- Raise the vehicle with a quickjack
- Remove the front bumper
- Drain coolant from radiator
- Take off radiator cover, hoses, and coolant reservoir
- Pull out fan shroud, AC condenser, and power steering reservoir
Taking Out Intake and Fuel Parts
To begin, the intake system must be removed. This means disconnecting the driver-side PCV tube and taking off the bolts that secure the intake. The mass air flow sensor and throttle body connections are unplugged, and the clamp to the throttle body is loosened. The intake assembly can then be pulled off the engine.
Next, the fuel rails are separated from the manifold and the fuel injectors are taken out for cleaning. After that, the intake manifold is unbolted and lifted off, opening up the intake ports for the work ahead.
Steps for Removal:
- Unplug PCV tube and intake mounting bolts
- Disconnect mass air flow sensor and throttle body wiring
- Loosen throttle body clamp
- Remove intake elbow and intake assembly
- Release fuel rails and remove injectors
- Unbolt and lift off intake manifold
Cleaning and Getting Surfaces Ready
With the intake parts out, the area around the cylinder head intake ports is cleaned. Brake cleaner and a paper towel are used to wipe away grime, especially from the cylinder heads and walls of the runners. An extension claw tool helps reach deeper spots.
The intake ports are covered with tape to keep out dirt or dropped objects during the rest of the install. Attention to cleaning and blocking off openings helps protect the engine from damage before reassembly.
Cleaning Checklist:
- Use brake cleaner for heads and runners
- Toothbrush or paper towel for stubborn buildup
- Tape over intake ports to prevent debris entry
Clean work areas and careful prep mean better results and fewer issues during installation.
Improvements to the Engine Cooling System
Radiator Upgrade
A new aluminum radiator was chosen to replace the factory unit. The upgraded radiator is noticeably thicker, with an extra row of cooling tubes that increases both coolant volume and contact area with air. This design helps the Mustang manage higher temperatures that come with supercharging. The chart below highlights key differences:
| Feature | Factory Radiator | Upgraded Radiator |
|---|---|---|
| Number of Cooling Rows | 1 | 2 |
| Coolant Capacity | Standard | Increased |
| Cooling Surface Area | Moderate | Larger |
The new radiator fit tightly but aligned well with existing hardware. After installation, the lower and upper hoses were reconnected, and the air conditioning condenser was reattached with new brackets. Studs from the original radiator were reused to secure the assembly.
Moving the Power Steering Fluid Tank
To install the supercharger kit, the power steering reservoir needed to be repositioned. The old reservoir was removed to provide space along the front of the engine. Its new location ensures the tank does not interfere with supercharger components and keeps fluid lines accessible for maintenance. Brackets and mounting points were adjusted so the reservoir stays secure under normal driving and during spirited use.
Factory Parts vs. Aftermarket Choices
The differences between stock and upgraded parts become clear when looking at performance needs. Factory radiators are designed for standard driving, limiting cooling capacity in high-horsepower situations. The upgraded radiator provides additional coolant flow, more cooling tubes, and a thicker core for better heat management.
A few comparisons:
- Stock: Designed for day-to-day use, not intended for forced induction or racing.
- Upgraded: Ready for supercharging, more durable under stress.
- Reservoir Positioning: Original location was fine for stock setups, but aftermarket modifications require adaptability.
By selecting these enhanced components, the cooling system can better handle the extra heat from the supercharged V8, supporting long-term engine health.
