Match a forklift engine water pump using the engine build, complete coolant-pump reference and applicable parts drawing. Separate engine cooling from hydraulic lifting. Ask for mounting, drive and connection details and the exact included scope. A similar housing or a reported overheating concern does not establish a replacement pump.
| Family | Information to retain | Continue research |
|---|---|---|
| Coolant pump assembly | Engine build, complete reference, mounting and connection drawing | Prepare a matching request |
| Cooling heat exchanger | Separate radiator identity and supplied scope | Research radiators |
| Maintenance documents | Retain engine build and earlier modifications | Review maintenance records |
| Hydraulic lifting pump | Different system and documented purpose | Research hydraulic pumps |
| Seal or repair scope | Request an explicit component list and applicable reference | Research repair-kit scope |
Perkins describes its engine water pump as moving water and coolant through the engine cooling circuit and matching the specific engine requirements. That supports the category distinction here, not a universal forklift pump specification. A hydraulic lifting pump belongs to a different system and should have a separate enquiry. Begin with the installed engine record and the component name used in its parts drawing. Do not choose a coolant pump because the word pump appears in a previous general maintenance order.
Existing records may identify an engine as Kubota V1505 or V2403, Toyota 1DZ-II, Mitsubishi S4S or Isuzu 4JG2. Preserve the exact recorded name, suffix and serial information where available. These examples help organise an enquiry; they are not a confirmed list of water-pump fitments. Kubota also distinguishes engine support from equipment support in its parts information. Ask the appropriate support route to locate the relevant engine build and drawing instead of assuming one family name fixes every coolant-pump interface.
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.
Request the full reference, mounting-flange drawing, documented drive or hub arrangement and connection details for the proposed coolant pump. Ask which housing, gasket, pulley or other components are included, if the offer and applicable documents identify them. Do not treat these as universally supplied parts. A catalogue image may clarify shape while leaving the installation unresolved. If the offered reference supersedes an earlier one, request the source of that change and any accompanying scope differences rather than accepting a visual match.
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.
This page does not convert a leak, unusual noise or overheating report into a confirmed water-pump diagnosis. It gives no instructions for opening a hot cooling system, rocking a pulley, removing a pump or selecting coolant chemistry. Preserve an existing professional assessment separately and use the applicable engine documents for service decisions. Manufacturer marketing inspection intervals and expected life figures are not transferred to other forklifts here. Request the documented requirement and exact offer before comparing delivery terms or price.
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-controlled site lists forklift engine applications, parts and service support. For a truck documented with a Yuchai engine, this is an original-engine documentation enquiry route. No alternator, starter, fuel pump or coolant pump listing, inventory or exact replacement is confirmed here. It is not an all-brand component supplier recommendation.

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.

Zhejiang Jinrui Pump — Forklift engine water-pump enquiries. The official company and category bodies establish a component-focused enquiry route, separate from the engine manufacturer’s general after-sales channel.
For an engine water-pump enquiry, identify the installed engine and cooling assembly separately from the forklift badge. The pump body, drive arrangement, mounting flange, hose connections, pulley and supplied gasket should be itemised where relevant. The enquiry must distinguish a complete pump assembly from an accessory or another pump function.
Supplier-coded product entries and familiar engine names are not independent compatibility evidence. The website domain and product labels do not establish Yanmar, Kubota or another manufacturer’s authorization, genuine origin, current stock or fitment.
No. Keep the engine cooling component and the hydraulic lifting component as separate documented requirements. Follow the component names and references in the applicable equipment records.
No. Keep the complete engine identity, component reference and applicable drawing. The example engine names on this page do not establish an interchangeable pump or approved fit.
Do not assume either. Ask for an explicit supplied-parts list and compare it with the documented requirement before evaluating the commercial offer.
The company site supports a Yuchai engine documentation route. A water-pump offer, stock, exact fit, original status and installation acceptance have not been verified by this review.
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.
