Description
Aeroflow Coolant Flow Restrictor Kit (Chev / Ford / Holden)
Precision anodised aluminium restrictor plates designed to optimize engine coolant dwell time and thermal efficiency under extreme motorsport conditions.
Product Overview
The Aeroflow AF49-1055 Coolant Flow Restrictor Kit offers motorsport engine builders and performance enthusiasts an effective solution for controlling coolant flow velocity through the engine block and radiator. By replacing or supplementing a standard thermostat with a fixed-orifice restrictor plate, you prevent coolant from circulating too quickly, ensuring optimum heat absorption from critical internal engine components and maintaining system pressure to prevent cavitation at high RPM.
Constructed from lightweight, CNC-machined aluminium, each plate features a distinct anodised finish (Red, Gold, and Blue) corresponding to orifice sizes of 5/8″, 3/4″, and 1″ inner diameter (I.D.). Designed to drop directly under standard 2-1/8″ outer diameter water outlets on Chevrolet, Ford, and Holden V8 engines.
Key Features
- ☑ Optimised Thermal Management: Regulates coolant dwell time to maximize heat transfer and stabilize engine operating temperatures.
- ☑ Three Orifice Options: Includes 5/8″, 3/4″, and 1″ I.D. plates to precisely tune cooling performance for track or strip.
- ☑ High-Grade Aluminium Construction: CNC-machined for precise tolerance and long-term durability under high coolant pressures.
- ☑ Colour-Coded Anodised Finish: Vibrant Red, Gold, and Blue anodising for effortless orifice identification and corrosion resistance.
- ☑ Direct Fitment: Standard 2-1/8″ O.D. dimensions fit under water necks/thermostat housings on Chev, Ford, and Holden engines.
