Radium Engineering® (11-23) Mustang S197/S550 Coolant Tank Kit
- In stock, ready to ship
Compatible: (2.3L/3.7L/5.0L/5.2L/5.4L/5.8L)
2011 - 2023 Ford Mustang
These kits are for the Ford Mustang GT, EcoBoost, V6, Shelby GT350, and Shelby GT500. It is designed to replace the plastic coolant tank found at the front of the engine bay.
The Radium Engineering coolant expansion tank is CNC machined from aluminum and consists of two halves that are bolted together. 
The low-profile design allows extra room in the engine bay for aftermarket forced induction or other modifications. The internal design features two chambers that are NOT isolated from each other. There are cross-over passages at the top and bottom. The Radium Engineering coolant header tank also has an internal swirl feature, which is to help aid in deaerating the system.
The kits include all parts necessary for installation. No permanent vehicle modifications are required.

*PRESSURE CAP SOLD SEPARATELY*
Pressure Cap
The OEM Pressure Cap cannot be reused. Below are the pressure ratings from Ford.
Mustang, S550: 1.45 Bar (21 psi)
Mustang, S197: 1.10 Bar (16 psi)
Shelby GT500: 1.10 Bar (16 psi)
The optional Radium Engineering pressure caps (sold separately) are manufactured from stainless steel with a race proven high pressure valve. An increase pressure relief cap provides a boiling point increase permitting improved cooling efficiency. This is necessary when tracking the vehicle in extreme conditions. 
Coolant expansion tanks are necessary for proper air bleeding in applications that utilize a low mounted radiator (such as a V-Mount) or rear mounted radiator. However, expansion tanks are also valuable if integrated in a common radiator setup. To allow heat expansion, traditional coolant systems require air to be present in the top portion of the radiator during low temperatures. An coolant expansion tank permits the radiator to be 100% filled with coolant in all conditions.
The Radium Coolant Expansion Tank holds 750mL. It is a 2-piece design constructed of CNC billet 6061 aluminum. The two halves (shown below) are bolted together along with a CNC billet aluminum radiator neck which accepts a standard 32mm "Mini" style pressure cap. The radiator cap must have a Type-A seal as shown HERE.
2x Bottom ports: -10AN ORB
1x Front port: -6AN ORB
The coolant expansion tank features two internal chambers. These chambers are NOT isolated from each other. There is cross-over passages at the top and bottom. This product is not a coolant overflow tank. Instead, it is designed to part of the pressurized coolant system.
The Radium Engineering coolant header tank also has an internal swirl feature, as shown below. Hot pressurized coolant from the cylinder head is sent into the vortex chamber's inlet tangentially and accelerated to a high rate of rotation. This is to help aid in deaerating the system.
The tank features three O-ring boss ports for a positive seal. Included are -6AN male adapter fittings (not tapered pipe threads). The lower ports are machined with 10AN ORB threads. The side port is machined with 6AN ORB threads. Included are three -6AN female 90 degree hose ends that screw onto the three -6AN male port fittings. They are lightweight black anodized aluminum and are used for push-lok style 3/8" ID hose. 
Includes:
-Billet Aluminum Coolant Tank
-Anodized Aluminum Mounting Bracket
-6AN Male Adapter Fittings (x3)
-6AN 90 degree Push-Lok Hose Ends (x3)
-Nickel-Plated Fittings and Sight Tube
-Billet Aluminum 32mm Pressure Cap Receiver
-Aluminum Pressure Bleed 1/4" Barb
-Stainless Steel Hardware
Mounting:
A laser cut black powercoated laser cut mounting bracket is included.

Pressure Caps
The optional Radium Engineering pressure caps (sold separately) allow the user to select a range of pressure. The purpose of a high pressure cap is to increase the boiling point in the cooling system providing improved cooling efficiency. Each cap is manufactured from stainless steel with a race proven high pressure valve. This is something to consider when tracking the vehicle in extreme conditions. 
Radium Pressure Cap - 1.1 Bar (110 kPA, 15.6 psi)
Radium Pressure Cap - 1.3 Bar (130 kPA, 18.9 psi)
Radium Pressure Cap - 1.5 Bar (150 kPA, 21.8 psi)
Radium high performance radiator caps are engineered to improve cooling efficiency. The radiator cap is an essential part of an upgraded cooling system and will help to safely maximize engine performance by controlling the coolant boiling point. Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability and feature silicone sealing elements that are superior to natural rubber gaskets. 
Available in 3 pressure ratings: 1.1Bar (16.0psi), 1.3Bar (18.9psi), and 1.5Bar (21.8psi). A higher radiator coolant pressure effectively raises the boiling temperature of the coolant, providing extra safety margin and preventing air pocket cavitation at the water pump
Also available in 2 common styles (Type-A and Type-B). Radium radiator caps are designed for mini size (32mm ID) radiator necks only. Please confirm what style your radiator uses prior to ordering.
