A-Premium A/C Suction & Discharge Hose Assembly Ford 4.2L V6 (1999–2004) — Direct-Fit, Four-Layer

If your Ford F-150 or F-150 Heritage with the 4.2L V6 is showing weak cooling, visible hose damage, or refrigerant leaks, a worn suction or discharge line can be the culprit. This A-Premium assembly is made as a direct-fit replacement for the original suction (low-pressure) and discharge (high-pressure) hoses on specified 1999–2004 Ford models. It matches OE reference numbers and offers a reinforced multi-layer build to withstand temperature swings and road wear.
