Radiator Coolant Silicone Hose Kit for Mitsubishi Eclipse (1995-1999) 2.0L 2.4L

High-Pressure Radiator Coolant Silicone Hose Kit for 1995-1999 Mitsubishi Eclipse (4G63T / 2G)

Upgrades the aging factory EPDM rubber coolant hoses with 3-ply nylon-reinforced silicone to prevent catastrophic coolant loss under high boost and extreme temperatures.

The Stock Eclipse Vulnerability

The OEM EPDM rubber radiator hoses on the 2G Eclipse are notorious for degrading over decades of thermal cycling. In the cramped engine bay of the DSM platform, ambient heat soak and elevated coolant temperatures accelerate rubber vulcanization, causing factory lines to swell, crack, and ultimately burst at the connection points. Furthermore, the stock spring clamps lose tension over time, leading to micro-leaks under the pressure surges typical of modified or high-boost applications.

The Engineering Solution

This upgraded hose kit is manufactured from premium 3-ply nylon-reinforced silicone, boasting a full 4.5mm wall thickness designed specifically for high-temperature and high-boost environments. Unlike factory rubber, the silicone construction maintains dimensional stability across an extreme operating range of -65°F to 500°F. Engineered to handle a sustained working pressure of 85 PSI and a burst pressure of 245 PSI, these hoses eliminate the risk of sidewall ballooning under heavy load. The kit includes matched heavy-duty clamps designed to provide constant, even tension around the silicone, ensuring a leak-proof seal at the radiator inlet and outlet, directly addressing the pressure requirements of modified 4G63T, 420A, and 4G64 engines.
