Pop the hood to check on your A/C and you notice it: the little cap on the air conditioning line is gone, cracked, or lost somewhere along the way. It's easy to shrug off a part this small, but that cap does a real job. It covers the A/C service valve on the suction line and helps keep dirt, moisture, and debris out of the port.
What This Part Does
This genuine OEM Mazda suction hose cap is also known as a return hose cap, A/C service valve cap, or lower pressure valve cap. It fits both the front and rear suction line positions and attaches to return hose, suction hose, rear suction line, and front suction line assemblies. It's included with those assemblies, but it's also available on its own, so you don't need to replace an entire line just to get a cap.
Why Genuine OEM Matters
A cap that doesn't match the original can fit loosely or look out of place. A genuine Mazda OEM part is built for the application it's listed for, so you get the fit the factory intended. This one arrives new, in new OEM condition, and is compatible with the 2.5L turbo and 2.2L diesel engines listed below.
