This OBX RH10391BK 2-piece silicone radiator hose kit is designed for 1998–2002 Chevrolet Cavalier 2.2L OHV (LN2). The kit includes one molded upper radiator hose and one molded lower radiator hose with an integrated small branch and follows the confirmed cooling-system routing for the application described below.
Each hose is manufactured from 100% pure silicone with multi-layer nylon reinforcement and a glossy black finish. This reinforced molded construction provides a durable performance replacement for aging factory rubber coolant hoses while giving the engine bay a clean, upgraded appearance.
1998–2002 Chevrolet Cavalier 2.2L OHV (LN2)
Fits the 2.2L OHV engine only. The 2002 2.2L DOHC Ecotec uses a different cooling layout; this kit does not fit the Ecotec or 2.4L engines.
See the complete Vehicle Compatibility section below and confirm that the vehicle, engine, hose shapes, and routing match before ordering.
100% Pure Silicone
Molded from 100% pure silicone with a smooth interior and glossy black finish for automotive engine-coolant service.
Multi-Layer Reinforced
Multi-layer nylon reinforcement supports hose strength and dimensional stability. The stated operating range is -165°F to 350°F, with a maximum temperature rating of 350°F.
Install & Clamp Correctly
Install over clean fittings, fully seat each hose, and position a properly sized OEM-style constant-tension or silicone-safe clamp behind the retaining bead. Tighten securely without crushing the silicone, then recheck after the first complete heating and cooling cycles.
Measured & Inspected In House
Kuku Performance photographs the actual kit and verifies its SKU, color, piece count, hose functions, and available connection measurements before shipment.

Vehicle Compatibility
Confirmed Factory Application:
1998, 1999, 2000, 2001, and 2002 Chevrolet Cavalier models originally equipped with the 2.2L OHV (LN2) four-cylinder engine and matching factory radiator-hose routing. Match by engine, not trim name alone.
Confirmed Engine / Chassis:
2.2L OHV / LN2. In 2002, Chevrolet also offered a 2.2L DOHC Ecotec engine; the shared 2.2L displacement does not mean the hose layouts interchange.
Included Hose Functions:
One upper radiator hose and one lower radiator hose with a molded small branch. This is a two-hose kit, not a complete cooling-system hose package.
OE/OEM Reference Numbers:
For comparing the factory OHV hose layout: GM 22698459 (upper radiator hose) and GM 22679467 (lower radiator hose). These are GM application references, not OBX numbers or a promise that factory pipes, clips, or clamps are included.
Known Exclusions:
2002 Cavalier 2.2L DOHC Ecotec (L61), 2.4L engines, and any vehicle whose hose layout differs from the photographed kit. Earlier RH10389 applications and 2003–2005 Ecotec models are not listed as direct applications.
Please review the complete photo set before ordering. Detailed views show the actual hose shapes, connection ends, and included pieces. The approximate dimensions above are reference values for the RH10391 kit.
