Confirm OTX TC 0001ZC-01 / WF2051 coolant filter assembly by its four-hole mounting base, spin-on interface, side connections and old-part photos.
When a truck cooling-system filter is replaced as a complete assembly, the mounting base and interface arrangement are just as important as the filter element. A similar spin-on filter can use a different housing, bolt pattern or side connection. Confirming the assembly first helps avoid ordering a canister when the service job actually requires the complete base.
This product guide focuses on OTX TC 0001ZC-01 coolant filter assembly. The recorded reference clue is WF2051 coolant filter assembly. The catalog does not provide a confirmed truck-model list or dimensional drawing for this code, so matching should be based on the complete code, the old assembly and clear installation photos.
TC 0001ZC-01 is a coolant filter assembly, not only a replacement canister. The visible assembly has a cast-metal body, a flat four-hole mounting base, a round spin-on filter interface with a central threaded spigot, and capped side connections. These visible features are practical comparison points when an old unit is removed from the truck.
Start by checking whether the existing part includes the mounting base and interface housing. If the old filter canister has been removed already, photograph the remaining base on the engine before ordering. That image can show the bolt layout and connection direction that a loose canister photo cannot provide.
The following information is documented for this specific product. It should be compared with the physical service part before a quotation is confirmed.
| Catalog Code | Reference Clue | Part Type | What to Compare |
|---|---|---|---|
| TC 0001ZC-01 | WF2051 coolant filter assembly | Complete coolant filter assembly | Four-hole base, spin-on interface, side connections, complete housing shape and old-part marking. |
The recorded WF2051 clue can help locate a purchase-list line, but it should not be used by itself as a universal interchange number. The part number, mounting arrangement and actual vehicle installation remain the deciding evidence.
The mounting base is the quickest way to separate complete assemblies that otherwise look alike. Photograph it from directly below or above so all four bolt holes are visible. Include the surrounding engine-side mounting surface when possible. This helps verify hole position, base outline and orientation before the part is packed or quoted.
Do not infer the bolt pattern from the filter canister. The canister may be a standard service item while the cast base and bracket arrangement are specific to the installation.
Take a straight-on photo of the round interface, including the threaded center spigot and sealing surface. Then photograph both sides of the housing with any protective caps or plugs left in place. The interface position and side connection direction are useful checks when several coolant-filter assemblies share a similar mounting base.
For an installed unit, avoid disconnecting lines solely to take a photo. A clear installed view, an old-part photo after removal and any readable casting or package marking normally provide enough information for an initial comparison.
Coolant assemblies, replacement filters and other coolant filter assemblies should be listed on separate purchase-order lines. Related filters and maintenance parts can be combined in the same shipment, but each cooling-system item should retain its own code and matching photos.
For uncertain lines, write “photo pending” rather than assigning an unverified reference. This keeps a mixed parts list practical while allowing each assembly to be checked against the actual installation.
Send TC 0001ZC-01 or WF2051 when available, complete old-part photos, the four-hole base image, front interface photo, installed orientation, truck and engine details when known, and quantity required. These details allow the complete assembly to be compared before quotation.
Send a coolant filter assembly inquiry with the images and purchase list for matching support.
