Material: heatresistant, pressuretested plastic for durability and leak prevention. Why customers need this part A failing or leaking reservoir cap can cause coolant loss, unstable engine temperature, and potential engine damage. This cap restores correct pressure control so the cooling system can operate as intended. Useful for routine maintenance, after cap failure, or as a replacement during coolant system service. Practical use scenarios 1) Fleet maintenance: worn caps across a ProMaster van fleet to reduce repeat overheating incidents and maintain consistent vehicle uptime. 2) Roadside : Swap in this cap after discovering a cracked or leaking reservoir cap during a roadside inspection to stop coolant loss and allow safe transit to a service facility. 3) Preventive service: Install during scheduled coolant system service to ensure the reservoir maintains correct pressure and helps prevent future leaks. Performance notes Built to withstand engine bay temperatures and pressure cycles typical of ProMaster applications. Matches original equipment part numbers for proper fit and system compatibility; verify OE number against your vehicle parts list before ordering. Installation the existing coolant reservoir cap with the matching OE number. If unsure, consult vehicle documentation or a qualified technician. Exact specifications and fitment are based on the OE numbers listed above and compatibility with 2014–2020 Ram ProMaster 1500/2500/3500 models.
