Gates 87-90 Jeep Wrangler 6-Cyl. 4.2L Lower Molded Coolant Hose

If your 1987-1990 Jeep Wrangler with the 4.2L 6-cylinder engine is running hot, it might be time to check the lower radiator hose. This molded coolant hose from Gates is built to replace the original, helping to keep your engine running at the right temperature. It's designed to fit the specific bends and connections needed for that engine, ensuring coolant flows smoothly from the radiator to the engine block.

Gates has been making cooling system parts for a long time, and this hose is a well-built replacement. It's made from materials that can handle the heat and pressure inside your cooling system. This hose is also a popular choice for a range of other vehicles, including Chevrolet Camaros and Novas from the early 70s, as well as various Dodge M300 and RM series trucks, and Jeep Cherokees and Comanches. Having the right shape and material means it won't kink or collapse under vacuum, which is important for consistent cooling.

Replacing a coolant hose is a pretty straightforward job for most DIYers, often just requiring a few clamps and some coolant. Make sure you have fresh coolant on hand when you swap out the old hose.
