Silicone Radiator Hose Kit for Mitsubishi 3000GT (1991-1999)

High-Temp Silicone Radiator Hose Kit for 1991-1999 Mitsubishi 3000GT (Z16A)

What it Does: The Silicone Radiator Hose Kit replaces the factory rubber coolant lines on the 1991-1999 Mitsubishi 3000GT to resist high-temperature degradation, withstand elevated cooling system pressures, and prevent catastrophic coolant loss.

The Stock Mitsubishi 3000GT Cooling Weakness

The cramped engine bay of the transverse **6G72** platform generates excessive underhood heat soak, accelerating the degradation of factory EPDM rubber coolant hoses. Over heat cycles, OEM hoses suffer from electrochemical degradation (ECD), micro-cracking, and thermal hardening. Under elevated cooling loop pressures or hard-driving thermal expansion, brittle factory hoses are prone to softening, ballooning, or splitting at the neck connections, risking immediate overheating and warped aluminum cylinder heads.

The Engineering Solution

Engineered as a direct-fit replacement for the **Z16A** chassis, this kit utilizes 3-ply reinforced silicone construction with a 4.5 mm nominal wall thickness. Silicone naturally resists ozone, UV degradation, oil vapor permeation, and extreme thermal cycling ranging from sub-zero conditions to over 350°F. The polyester reinforcement layers maintain rigid burst pressure resistance without expanding or collapsing under dynamic coolant flow. Complete with four stainless-steel worm-drive clamps, this kit secures leak-free junction clamping at the radiator inlet, outlet, and water housing necks.

Frequently Asked Questions & Fitment Warnings

Does this fit the Z16A 3000GT?

Yes, this is a direct fit for the 1991-1999 Mitsubishi 3000GT equipped with the **6G72** engine and factory radiator plumbing layout.

Do I need to bleed the cooling system after installing these hoses?

Yes, you must refill with factory-spec ethylene glycol coolant and thoroughly bleed air from the thermostat housing bleed port to prevent localized hot spots and air cavitation.

The Mitsubishi Performance Caliber

Built to handle the demanding boost and heat thresholds of twin-turbo and high-revving naturally aspirated JDM platforms, this cooling component provides the thermal reliability required for aggressive street driving and sustained track sessions.
