Coolzone Valve Core (41-5386)

Description

Genuine Coolzone · Part no. 41-5386

This Coolzone 41-5386 is a single spring-loaded valve core for R134a air conditioning service ports, an M10 Eaton type according to its listing code. Fit it when a port leaks past its core or a coupler has damaged the old one. It is changed with a valve core tool and also comes in Coolzone's kits.

Good to know

• How do I know I need the M10? Take the old core out and compare thread and length; R134a cores come in more than one size, and this is the M10 one.
• What does a leaking core do? A valve core that leaks lets the refrigerant out slowly, so the air conditioning cools less and less over the weeks. A leak test at the port after fitting shows whether the new core has sealed.
• Can I change it on a charged system? No. Car air conditioning must be recovered with a recovery machine before any part that holds refrigerant is opened; the gas must never be let out into the air.

Which one?
