Coolant Exchanger Parts

Alamo stocks parts for Mahle and Flo-Dynamics coolant exchanger machine lines — both current product families and several older platforms still in shop service. Provide the machine model and serial number when ordering; some component revisions affect interchangeability across production runs.

Inspect hose kits every 90 days for cracking, kinks, and end-fitting wear. Replace at the first sign of failure or every 18 to 24 months of regular use, whichever comes first. Coolant exchanger hoses see thermal and chemical cycling that ages elastomers faster than typical shop hose.

Modern domestic and import cooling systems use a wide variety of cap, neck, and quick-connect interfaces. Universal adaptor sets cover the majority of common vehicles, but specialty platforms — European luxury, hybrid vehicles, and some heavy-duty pickups — require dedicated adaptors. Verify coverage before promising a service appointment.

Generally no. Mahle designs proprietary connections, electrical interfaces, and adaptor patterns. Mixing brands is not supported and voids the equipment warranty. Stay with Mahle OEM parts for Mahle machines and Flo-Dynamics parts for Flo-Dynamics machines.

Internal pump assemblies are replaceable as complete modules in most current machines. Seals and impellers are not field-serviceable items on most Mahle and Flo-Dynamics machines — replace the pump module as a unit when flow rate drops or leakage develops at the seal.

Most machines use an inline particulate filter on the recovery line to catch debris from the cooling system being serviced. Replace cartridges per the machine's service interval — typically every 100 to 250 exchanges, sooner with consistently dirty cooling systems. Restricted filters reduce flow rate and exchange completeness.

Yes. Provide the machine model and serial; the Alamo parts desk will build the recommended PM kit, including a hose set, filter cartridge, and any service-interval components specific to that model. Bundling reduces shop downtime versus ordering pieces separately.

Shipping timing depends on current stock and fulfillment source. Less common adaptors and full pump modules may require additional lead time. Contact the parts desk to confirm the current ETA for a specific part number.
