Coolant on the driveway or a temperature warning on the dash? Get the leak checked, the right pump selected, and the cooling system tested before your E350 returns to the road.
We explain whether the pump needs replacing or another cooling fault needs attention, with a fitted quote before work begins.
Tell us what changed. These symptoms help direct the inspection, but none identifies the failed part by itself.
A seal, pump housing, hose connection, expansion tank, or radiator may be leaking. Dried deposits near the pump deserve a closer look, but coolant can run down from a higher connection. Arrange prompt inspection even if the temperature appears normal. If you are unsure about driving with a recurring leak, call to discuss transport.
A worn mechanical pump bearing can make noise or develop play. The belt tensioner, idler, and other driven accessories also need comparison before a pump is ordered.
Poor circulation is one possibility. Fan operation, thermostat behavior, coolant quantity, and radiator airflow can produce similar symptoms. Replacing a pump will not repair a separate fan fault.
Planning estimates in AED include VAT for the work listed. Your engine, pump specification, access, and parts choice determine the written total.
The V6 range allows for a new compatible aftermarket pump. A genuine Mercedes-branded option is priced for the actual application. The itemized quote names the manufacturer, pump, included work, and availability. Other E350 engine configurations receive a separate fitted estimate.
Belts, tensioners, extra hoses, radiator or fan repairs, contamination cleanup, recovery, and damage from overheating are excluded unless listed. The AED 250–450 assessment is a standalone planning estimate. Do not assume it is included in the replacement range or automatically credited. The workshop explains the assessment charge and combined payable total before you approve work.
Cold leak inspection, a suitable pressure test, and initial temperature or fault-data checks. Extended electrical diagnosis and internal engine testing are separate.
A new compatible aftermarket pump, required seals, normal access labor, specified coolant refill, bleeding, and leak and operating checks.
An additional allowance when a separate thermostat or housing needs replacement and access is shared. This is added only when the fault or condition supports it.
An applicable auxiliary pump, normal fitting, electrical operation check, and coolant correction. It is a different repair from replacing the main engine pump.
E350 engines and cooling arrangements vary across generations and markets. The common V6 examples here relate to applicable M272 and M276 gasoline engines. Other gasoline, diesel, or electrified E350 configurations can use different components and cooling circuits. We identify the fitted engine after you contact us; registration year alone does not establish the pump or price.
The main pump circulates engine coolant. A smaller auxiliary pump serves a particular circuit where fitted. The quote identifies the failed unit rather than treating every coolant-pump code as the same repair.
We check the fitted engine and application before ordering. A VIN or existing part number may help later, but you only need the model and symptom to start an inquiry.
Drivetrain and surrounding equipment can change access. Labor is based on the actual removal required, not an automatic surcharge for a badge.
Do not replace a sound pump solely because it reaches a universal mileage. Leakage, bearing condition, operation, history, and the vehicle maintenance information guide the decision.
The part choice affects the installed total and availability. Compare a named pump with the same fitting, coolant, and checks included, rather than comparing a parts-only price with a complete repair.
A genuine pump is matched to the actual vehicle application. Its current price and lead time are quoted separately from the aftermarket planning allowance. The quote identifies the supplied assembly and any seals or hardware included with it.
The main V6 estimate uses this category. The manufacturer and application are specified before approval. A supplier that also produces original-equipment parts does not make every item in its catalog identical to a Mercedes-branded part.
Review the named pump, required seals, coolant, access labor, and final checks together. Applicable parts and workmanship terms depend on the selected product and job. Used pumps and unidentified parts are not the basis of the new-pump estimate.
A leaking pump shaft seal, worn bearing, damaged housing, or confirmed circulation fault can justify a complete pump. Rebuilding a common sealed pump is usually less practical than fitting the correctly specified replacement. A new gasket alone will not cure internal wear.
If coolant comes from a hose, connector, thermostat housing, or tank, repair that source. We explain why the pump can remain when its condition and operation are satisfactory. This keeps the repair focused on the cause of the loss.
A worn belt, rough pulley, brittle hose, or faulty thermostat may be sensible to address during the same visit. Required parts and optional preventive work are separated so you can compare the extra cost and shared labor.
The aim is to locate the fault without asking you to reproduce an overheating event. The engine is allowed to cool before opening or pressure-testing the circuit.
We inspect the pump area and trace wetness or residue back to its source. A suitable pressure test helps reveal leaks that are not obvious while parked.
We check accessible mechanical drive components, bearing condition, temperature behavior, and relevant control data. The method depends on the fitted pump.
We review the thermostat, fans, radiator, tank, cap, and hoses when the symptom calls for it. One abnormal reading does not automatically condemn a pump.
Tell us if the engine stopped, steamed, or was driven with a warning. Further engine checks may be needed before a pump repair can be treated as the full solution.
A straightforward replacement often needs around three to five working hours once the engine is cool and parts are available. This is working time, not a guaranteed arrival-to-collection window. Cooling the engine, waiting for parts, investigating additional faults, and verifying operation can extend the stay. We explain the expected collection time with the repair quote.
Review the diagnosed fault, named pump, seals, coolant, labor, and any separate related work. Parts availability and the expected workshop stay are checked before the job starts.
Drain the required coolant, gain access, remove the failed pump, and prepare the sealing surface. Fit the correct seals and hardware using the applicable installation procedure.
Refill with coolant suitable for the vehicle specification and remove trapped air using the required method. Coolant color alone does not establish compatibility.
We check the repaired area for leakage, monitor warm-up and temperature behavior, and review relevant fan or heater operation. Recheck the coolant level under the proper conditions.
These are planning scenarios, not completed customer jobs. Each includes VAT for the described work and assumes the stated component is fitted and its fault confirmed. These repair totals do not promise a free initial assessment; its treatment is stated in the combined quote.
New compatible aftermarket pump and seals, normal access, coolant refill, bleeding, and final checks. No thermostat, belt-drive renewal, or engine damage repair.
A new compatible aftermarket main pump plus a separately diagnosed thermostat, with shared access, required seals, coolant, and verification. Additional hose or radiator work is excluded.
A new compatible auxiliary coolant pump for an applicable heater circuit, after electrical and operation checks confirm the fault. Includes normal fitting and coolant correction. This scenario applies only where that circuit and pump are fitted; it excludes the main engine pump.
The repair record identifies the fitted pump and agreed related items. At handover, we explain the coolant used, completed leak and operating checks, and any separate concern. The selected part and applicable coverage are discussed before approval, so collection is a review of the agreed work.
Follow any coolant-level recheck instructions with the engine cold. A recurring warning, fresh leak, unusual noise, or rising temperature needs prompt attention. Stop safely if overheating returns. Do not keep adding coolant to cover an unresolved loss.
Tracing the source first helps avoid replacing a serviceable pump. Separating essential work from optional related parts lets you direct the budget toward the fault.
Correct refill and operating checks help establish whether the original cooling concern has been resolved. A fitted pump alone does not demonstrate that every cooling component works correctly.
For other cooling layouts, see our Mercedes water pump service. For broader maintenance or a separate E-Class concern, use the E350 repair page. Vehicle-specific operating guidance is available through the Mercedes owner’s manuals.
Allow AED 1,800–3,200 including VAT for a common V6 main-pump job using a new compatible aftermarket pump, required seals, normal labor, coolant, bleeding, and checks. Genuine parts and other engine configurations need a separate quote. The standalone assessment estimate is AED 250–450; its inclusion or credit is agreed before approval.
Tell us what happened, including whether you kept driving or the engine stopped. Additional checks may be needed to assess consequences beyond the pump. A pump replacement quote does not automatically include internal engine repairs or guarantee that overheating caused no further damage.
An active leak can become worse without warning. Do not drive with steam, rapid loss, rising temperature, or a stop warning. Call to discuss recovery. Even a small leak needs prompt assessment; topping up is not a repair.
The stated pump replacement estimates include the selected pump, required seals, normal labor, specified coolant, bleeding, final checks, and VAT. Related components and overheating damage are separate unless included in your quote.
Only when its condition, operation, assembly design, or agreed preventive work justifies it. A pump fault alone does not prove that a separate thermostat has failed.
A genuine Mercedes-branded option can be quoted where available. Suitable quality alternatives may also be discussed. The quote identifies the selected part, total, availability, and applicable terms.
A straightforward job may fit within one working day once the engine has cooled and parts are ready. Extra diagnosis, contaminated coolant, damaged fasteners, or related faults can extend the schedule.
There is no single interval that should be applied to every E350 engine and pump. Follow the relevant maintenance information and assess leakage, noise, condition, and operating symptoms.
No. Start with your E350 and the cooling symptom. The workshop can request further vehicle details later when matching parts or confirming the estimate.
Describe the leak, noise, or dashboard warning. We will help identify the source, compare the applicable pump choices, and provide an itemized fitted quote after assessment. If the engine is overheating, call before trying to drive to the workshop.
