Subjected to decades of engine bay heat cycles, oil exposure, and vibration, the factory rubber becomes brittle, leading to micro-cracking and sudden structural failure. When navigating slow, low-airflow trails or idling in heavy traffic, the 4.0L engine builds significant under-hood heat, pushing weakened rubber hoses past their bursting threshold and risking catastrophic coolant loss.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 3-ply reinforced silicone hose kit provides a permanent fix to the TJ's cooling weak points. Engineered from premium multi-layer silicone, these hoses feature a robust 4.5mm wall thickness designed to withstand extreme thermal loads ranging from -65°F to a blistering 500°F. Unlike standard rubber, the vulcanized silicone resists ozone, UV degradation, and localized heat soak from the exhaust manifold. With a bursting pressure rating of 245 PSI and sustained working pressure handling up to 0.9Mpa, the structural integrity of your cooling system is dramatically improved. The exact-fit dimensional tolerance (+\/-0.5mm) ensures a leak-free seal around the water pump and radiator necks.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1997-2001 Jeep Wrangler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4.0L AMC 242 Inline-6 \/ TJ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e181 hp \/ 222 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1997-2001 Jeep Wrangler TJ 4.0L (Left Hand Drive ONLY)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the punishing environments of trail crawling and heavy towing, upgrading to multi-ply silicone guarantees your cooling system matches the legendary reliability of the 4.0L inline-six.
