Identify a forklift radiator by the truck installation, engine build, complete radiator reference and applicable cooling-system drawing. Keep the radiator separate from the coolant pump and other heat exchangers. Request the mounting, connection and included-scope records for the exact offer. Core dimensions or a similar photograph alone do not confirm a replacement.

| Coolant circulation pump | Separate pump reference and documented interfaces | Research water pumps |
| Engine maintenance | Existing cooling records and modifications | Review maintenance scope |

Perkins describes coolant moving through the engine circuit before reaching a radiator. That is useful category context, not a radiator fit specification for another forklift. Record both the installed engine and the truck installation because the purchase concerns a component in that complete equipment arrangement. If earlier files identify Toyota 4Y, Nissan K25 or Mitsubishi S4S, preserve those names exactly as recorded. They are identification examples, not a list of interchangeable radiator applications or confirmation of a particular engine installation.
Ask for the complete reference and the mounting and connection drawing for the proposed radiator. Core size, inlet and outlet positions, bracket locations and any documented cap or associated-cooler requirements belong in the comparison where the equipment records specify them. This guide supplies none of those values. Do not dismantle equipment to obtain enquiry measurements. Existing drawings, safely available photographs and a supplier request for the missing document are better than turning an estimated dimension into a purchase specification.
Begin with the truck manufacturer, full model, serial number and the name or position used in its parts documentation. Retain the assembly reference when the component belongs to a documented engine build or fuel/cooling/electrical assembly. An incomplete reference should remain incomplete in the enquiry: do not silently add a familiar suffix or convert an unclear photograph into a catalogue designation. Existing records and safely available label photographs can help a supplier ask the right follow-up question. This page does not require dismantling or operating equipment to obtain information.
Ask the offered item to state its documented construction and what is included. A radiator core, a complete assembly and a separately quoted fan or shroud are different purchasing scopes. Do not transfer general claims about copper-brass or aluminium construction into an assumed cost, repairability or performance ranking. If the supplier proposes a different material or installation arrangement, request the written basis and unresolved differences. Keep the required technical review separate from a discussion of price, origin and delivery.
Ask every candidate to quote the same written requirement. Separate the original equipment reference, the supplier catalogue reference and the reference actually offered. Ask for the offered manufacturer, condition, supplied quantity, included components and documents. A substitution proposal should list unresolved differences rather than hide them behind the word compatible. Compare the commercial offers only after those differences are visible. A lower price or shorter delivery time does not establish technical acceptance, and a directory entry is not an inventory reservation.
An overheating concern, visible staining or a reported coolant loss is not proof that a radiator replacement is the correct action. Keep the existing professional assessment distinct from the part enquiry. This page provides no hot-system opening, flushing, pressure-test or repair procedure and no universal coolant chemistry. The conditional Yuchai profile can help identify an installed Yuchai engine, but it does not establish who supplies the truck radiator. Ask the equipment-document route to resolve that responsibility if it remains unclear.
Record who will resolve the remaining technical questions and which documents will support that decision. State quantity, destination, required delivery information and the scope of any separately quoted service. Keep a professional condition assessment distinct from the purchase request. This is an identification and procurement guide, not a removal, adjustment, repair or return-to-service procedure. If the supporting reference cannot be obtained, preserve the question as unresolved instead of buying on a symptom, a generic category picture or an assumed cross-reference.
The source notes below document the category information actually reviewed. A company catalogue can establish that a business presents a relevant product family, but that does not prove that a pictured item is currently available or that a proposed component fits another manufacturer’s machine. Request written confirmation for the exact offered item. Keep any claimed original status, certification or authorised relationship distinct from the item description and ask for its basis. This guide adopts no marketing durability figures, market-share claims or unnamed customer approvals.
These company routes are tied to readable manufacturer or company-controlled material reviewed on 3 October 2026. Use the stated scope to begin a shortlist. A profile does not establish current stock, certification, authorisation or a match for your truck.
The company site includes forklift engine applications, parts and service support. For a documented Yuchai engine, use this as an original-engine identification route. No radiator or filter offer, current stock or exact replacement is established here; truck cooling and hydraulic filtration may require separate equipment documentation.

Open supplier profile →For additional candidates, use the parts supplier directory. Ask each supplier to return the exact proposed item, condition, included documents, unresolved differences, quantity, destination and current delivery terms. Keep technical acceptance separate from commercial availability.
Separate the truck identity, engine identity and installed component reference before making a request. Manufacturer after-sales channels and radiator specialists answer different procurement questions.
The Yuchai profile is an engine-identity and after-sales route; it does not confirm this individual service item is available. Hengchen is a radiator route, not a pump or filter supplier.
Official website scopes reviewed on 4 October 2026. Current inventory, authorization, genuine origin and matching remain to be documented in a supplier offer.

No. Preserve the assembly reference and installation records, and request the proposed mounting, connection and supplied-scope documents. Similar external dimensions do not establish an accepted replacement.
No. The Yuchai profile is an installed-engine documentation route. This review does not confirm a radiator offer or stock, and truck installation records may be needed separately.
No. Keep symptom and condition assessment separate from purchasing. Identify the component requirement using the equipment records and an appropriate professional assessment.
Do not assume it. Ask for the exact included-components list and separately identify any required items. Compare equivalent written scopes before comparing commercial terms.
The references below support the stated category and identification examples. Manufacturer marketing statements are not treated as independent tests. No model-specific operating values, repair procedures or performance promises are inferred for another machine.
Send the equipment identity, complete component reference, existing drawings or label photos, requested scope, quantity and destination. Mark missing information unknown and ask suppliers to answer the same written requirement.
