Description
Radiator hose kit for 1986–1992 Toyota Supra delivering improved cooling-system reliability through durable black silicone construction.
The Mishimoto Radiator Hose Kit BlackSilicone 86-92 Toyota Supra replaces aging rubber hoses with silicone components engineered to resist heat, ozone, and long-term degradation for consistent coolant flow and reduced maintenance intervals.
- Black silicone upper and lower hoses — Silicone construction maintains dimensional stability under thermal cycling, helping preserve hose shape and coolant routing for reliable cooling performance.
- Includes both upper and lower hoses — Complete replacement of primary radiator hoses ensures matched material and fit across the cooling circuit for predictable system behavior.
- Four worm-gear clamps included — Supplied clamps provide secure, adjustable clamping force to establish and maintain leak-free connections at the radiator and engine necks.
- Mishimoto brand quality — Manufactured and packaged by Mishimoto with a focus on OEM-fit replacement components for motorsport-informed durability and repeatable fitment.
Installation is a direct-replacement service item that addresses common aging-failure modes of factory rubber hoses. By using silicone hoses, the kit reduces the risk of hose swelling, cracking, and softening that can lead to coolant loss and overheating.
What this kit provides in practice: improved material longevity in high-heat environments, matched hose geometry for straightforward installation, and included clamps to complete the swap without sourcing hardware separately.
