Radiator Hose Kit for Toyota Mark II JZX90 1JZ-GTE Silicone High-Temp Engine Cooling Upgrade
Upgrade your cooling system with the Silicone Radiator Hose Kit, a premium direct-replacement set engineered for the Toyota Mark II JZX90 with a 1JZ-GTE engine. This kit replaces the original hoses with a high-performance silicone solution designed to handle higher temperatures and pressures, delivering reliable cooling under boost and in hot conditions.
Manufactured by IILK8, the hoses use a 3-ply silicone construction with a 4.5 mm wall, combining durability with essential flexibility to fit the tight engine bay. The working temperature range from -65°F to 500°F (-54°C to 260°C) and a working pressure of 0.3–0.9 MPa mean your cooling system stays stable even during aggressive driving. A bursting pressure of 245 psi provides a robust safety margin against sudden pressure spikes, protecting the engine from overheating and leaks.
Designed for direct OE replacement, this silicone hose kit maintains consistent coolant flow and helps prevent common failures associated with aging rubber hoses. It’s an excellent choice for enthusiasts upgrading a 1JZ-GTE-powered Mark II for enhanced reliability, boosted performance, or everyday driving resilience.
