Used Truck Water Pumps & Kits, Coolant Pumps & Housings

Used truck Water Pumps & Kits

Water Pumps & Kits are an important part of the engine cooling system on a truck, lorry or HGV. The coolant pump circulates coolant through the engine block, cylinder head, radiator, heater circuit and related cooling pipework so that operating temperature stays under control. On heavy commercial vehicles, the cooling system works hard for long periods under load, especially on motorway work, construction vehicles, refuse trucks, distribution fleets and tractor units pulling heavy trailers. A worn, leaking or incorrect coolant pump assembly can quickly lead to poor circulation, overheating, coolant loss and possible engine damage.

VRA Truckparts lists used OEM Water Pumps & Kits removed from dismantled commercial vehicles when suitable stock is available. Current listings in this category may include genuine used coolant pump assemblies, water pump carriers, pump housings and related engine cooling components. One example from this category is a genuine used MAN TGX / MAN TGS coolant pump housing assembly, listed with part number 51063305002 and associated reference 51063305040, with casting reference 51.06330-5002. As with all used truck parts, stock changes as donor vehicles are dismantled, so buyers should check each listing carefully for the exact OEM number, photos, included components and vehicle application.

What you will find in the Water Pumps & Kits category

The Water Pumps & Kits category is focused on used OEM engine cooling parts connected with coolant circulation. Some items may be complete assemblies, while others may be housings, carriers or related fittings depending on how the part is supplied from the donor vehicle. Availability is limited by the trucks being dismantled, so the exact items shown may vary over time.

• Used truck coolant pumps and water pump assemblies for HGV engine cooling systems.
• Coolant pump housing assemblies and water pump carrier units, including MAN TGX and MAN TGS examples where available.
• OEM-referenced parts such as 51063305002, 51063305040 and casting reference 51.06330-5002 when shown in the listing.
• Mounting housings, pump bodies and carrier assemblies that connect to the engine block and cooling pipework.
• Used genuine components removed from donor commercial vehicles and photographed for comparison.
• Related fittings, mounting points and gasket faces that should be checked against the original part before purchase.
• Engine cooling parts that may sit alongside radiators, fans, coolant pipes, thermostats and expansion tanks within the wider cooling system.

Truck brands & typical applications

Product examples in this Water Pumps & Kits category currently support MAN truck applications, particularly MAN TGX and MAN TGS models where the part number and physical layout match. MAN cooling components can vary by engine type, model year, Euro emissions specification and ancillary layout, so matching by model alone is not enough. Other European truck brands may appear in this category as stock changes, but buyers should always treat the listing details as the source of truth.

• MAN TGX: coolant pump housing and water pump carrier assemblies may be listed with MAN OEM references.
• MAN TGS: similar engine cooling assemblies may be used depending on engine and specification.
• HGV tractor units and rigids: water pump parts should be checked against the original engine installation.
• Commercial vehicle engines: pump housings may differ by belt drive layout, hose connections and mounting points.
• Used OEM applications: part numbers, casting numbers and donor vehicle details are more reliable than visual guesswork alone.

Why Water Pumps & Kits matter

The coolant pump is central to engine protection. If coolant is not circulated properly, the engine can develop hot spots, the cab heater may perform poorly, the radiator may not transfer heat effectively and warning lights may appear under load. On an HGV, a cooling fault can mean downtime, recovery costs and potential damage to expensive engine components. Correct Water Pumps & Kits help maintain steady coolant flow, support radiator efficiency and keep the engine operating within its designed temperature range.

Used OEM Water Pumps & Kits can be a practical option when the original part number must be matched closely. Pump housings and carrier assemblies often have specific bolt patterns, machined faces, coolant galleries and pipe connections. An incorrect aftermarket or non-matching part may appear similar but fail to line up with the engine, belt arrangement or pipework. For workshops and fleet operators, comparing the original component with the listing photos and references is essential before ordering.

Typical reasons to replace Water Pumps & Kits

Water Pumps & Kits are often replaced during engine cooling repairs, coolant leak investigation or larger engine maintenance work. Sometimes the pump itself has failed; in other cases, the housing, carrier or mounting face is damaged or corroded. Used OEM parts can be useful where the correct housing or assembly is no longer easily sourced new, or where the repair requires the exact original layout.

• Coolant leaks from the pump body, housing, gasket face or seal area.
• Worn internal bearing or noisy pump operation on the original assembly.
• Cracked, corroded or damaged coolant pump housing after long service life.
• Broken mounting lugs, stripped threads or damaged bolt holes on the carrier.
• Overheating or poor coolant circulation after other cooling system faults have been checked.
• Incorrect previously fitted part with mismatched hose outlets, belt alignment or mounting points.
• Accident, front-end impact or engine bay damage affecting the cooling assembly.

How to choose the correct Water Pumps & Kits

Choosing the correct used Water Pumps & Kits is mainly about matching the exact part rather than relying only on the model name. Engine cooling parts can change across production years and emissions standards, and similar trucks can use different pump housings depending on engine variant and ancillary equipment. Before ordering, remove or identify the original part where possible and compare every visible reference with the listing.

• Check the truck make, model and generation, such as MAN TGX or MAN TGS where relevant.
• Confirm the engine type, engine code and Euro emissions standard if known.
• Compare OEM numbers such as 51063305002 and 51063305040 when they appear on the old part or listing.
• Look for casting numbers, including formats such as 51.06330-5002, as these can help identify the housing.
• Compare mounting holes, bolt pattern, gasket face shape and overall housing design.
• Check coolant pipe outlets, hose connection positions and any blanking plugs or ports.
• Confirm what is included in the listing: pump, housing, carrier, fittings or assembly only.
• Use the photos to compare condition, layout and visible references with the part being replaced.

If you are unsure whether a listed part will match your truck, use how to find the right truck part for practical identification advice or read about compatibility and VIN checks. Supplying the registration, VIN, OEM number and clear photos of your old water pump or coolant pump housing can make it easier to confirm the correct used OEM part before purchase.

Used OEM parts from dismantled trucks

VRA Truckparts specialises in used genuine OEM truck parts removed from dismantled commercial vehicles. Water Pumps & Kits listed on the site are taken from donor trucks, visually checked where practical, photographed and labelled with available part numbers or casting references. The individual product page should be read carefully because it shows the actual part being sold, including its condition notes, visible wear, included fittings and any references found on the component.

Used engine cooling parts can show normal signs of service, age, staining or external corrosion, especially around coolant passages and mounting faces. This is why clear photos and honest item descriptions matter. Buyers should inspect the listing images for gasket faces, cracks, damaged lugs, corrosion and missing fittings. Where a listing states that the item has been visually inspected, this should not be confused with a claim that every water pump has been fully bench tested.

Related engine cooling checks

A failed water pump or coolant pump housing is often connected with wider cooling system symptoms. Before fitting a replacement, workshops commonly inspect the radiator, coolant hoses, thermostat, fan operation, drive belt, expansion tank and pressure cap. If the original pump failed due to overheating, contamination or coolant neglect, it is sensible to flush the system and check for blocked passages or poor coolant flow. A replacement Water Pumps & Kits item should be fitted with suitable seals, gaskets and coolant according to workshop practice and the vehicle manufacturer’s requirements.

When comparing a used OEM pump housing, pay close attention to the machined faces and pipe connections. A small difference in outlet angle or bracket position can make the part unsuitable even if it looks broadly similar. On MAN TGX and MAN TGS applications, part references such as 51063305002, 51063305040 and 51.06330-5002 are especially useful for narrowing the match, but they should still be checked alongside the vehicle details.

Delivery, payment & returns

VRA Truckparts supplies used truck parts to workshops, fleet operators, repairers and trade buyers. Each Water Pumps & Kits listing should be reviewed before ordering so you know exactly what is included and whether the part matches your vehicle. For ordering information, see delivery and shipping, payment and VAT information and returns and refunds. Condition information for used parts is also explained on warranty and part condition.

If you need help identifying a coolant pump, pump housing or water pump carrier, provide as much information as possible before ordering. The most useful details are the truck registration or VIN, the old OEM number, casting number, engine type, photos of the original part and any visible damage. This helps reduce the risk of ordering a Water Pumps & Kits item that is visually similar but not correct for your truck.
