Aston Martin High-Temperature Radiator Assembly – HY53-8005-AA HY538005AA

Aston Martin High-Temperature Radiator Assembly – HY53-8005-AA

Maintain stable engine cooling performance with a complete replacement center high-temperature radiator assembly built around Aston Martin reference HY53-8005-AA / HY538005AA. The aluminum-core heat exchanger is designed to restore the cooling capacity, airflow path and mounting layout required by Aston Martin high-temperature cooling systems.

OE Reference & Fitment

Reference number: HY53-8005-AA / HY538005AA.

This radiator reference is used across Aston Martin high-temperature cooling applications including DB11 and related models equipped with the matching radiator layout. Match the original radiator label, mounting points, hose positions and part number before installation.

Construction & Performance

• High-density aluminum cooling core for efficient heat transfer
• Vehicle-specific mounting tabs and hose connection positions
• Replacement design for the center main high-temperature radiator
• Built to restore cooling performance after impact damage, leakage or restricted airflow
• Direct service replacement format for the original cooling-system location

Installation Guide

Professional installation is recommended because the cooling system must be drained and properly refilled. Remove the front undertrays and required cooling modules, disconnect the radiator hoses, transfer any reusable seals or brackets, install the replacement radiator, reconnect all lines and refill with the coolant specification required by the vehicle. Bleed the system completely and pressure-check for leaks before road use.

FAQ

What part number does this radiator replace?
HY53-8005-AA / HY538005AA.

Is this the engine cooling radiator?
It is the center main high-temperature radiator assembly used in the vehicle’s high-temperature cooling circuit.

What material is the core?
The radiator uses an aluminum heat-exchanger core for efficient thermal transfer and low weight.

How should fitment be confirmed?
Match HY53-8005-AA plus the hose locations, side brackets and overall radiator shape to the original part.

Should the cooling system be pressure-tested after installation?
Yes. The system should be filled, bled and pressure-checked after replacement.

When should a radiator be replaced?
Replacement is appropriate after coolant leakage, bent or damaged core fins, impact damage, blocked internal flow or loss of normal cooling efficiency.
