Coolant keeps disappearing
A hose, radiator, pump, cap, or internal leak may be responsible. Pressure testing and an external leak check decide whether engine testing is needed.

Diagnosis before dismantling
Quote before repair
Start with the symptom
Does your Mercedes need a head gasket?
A head gasket seals the joint between the cylinder head and engine block. Similar symptoms can come from cooling, ignition, or other engine faults, so a warning light alone is not a reason to authorize this repair.
White exhaust and rough starts
Persistent vapor with coolant loss needs investigation. Brief condensation is different. Cylinder checks help separate coolant entry from ignition or fueling faults.
Oil and coolant contamination
An oil cooler or an internal engine leak may be involved. Residue only under the oil cap is not conclusive. The fluids and relevant heat exchanger need checking.
Choose the work the engine needs
Gasket replacement or a larger repair?
The gasket itself is replaced, not rebuilt. The important choice is whether the existing head and engine are healthy enough for that repair.
Estimated repair budgets
Mercedes head gasket replacement cost
Use these AED ranges to plan an inspection, not as a fixed quotation. The engine and damage found matter more than the badge alone.
AED 4,200–9,500
Selected gasket-replacement scenarios. Major damage is quoted separately.
| Vehicle and repair assumption | Estimated AED | What changes the quote |
|---|---|---|
| Initial cooling-system and head-gasket diagnosis | 250–650 | Cold inspection, pressure testing where suitable, scan data, and the tests required for the symptoms |
| C-Class four-cylinder, reusable cylinder head | 4,200–5,800 | Engine generation, access, gasket set and previous overheating |
| E-Class, straightforward single-head repair | 4,800–6,500 | Actual engine, seals disturbed and head condition |
| Selected GLC/GLE applications, affected head only | 5,800–7,500 | Four-cylinder versus V-engine, bank involved and access |
| Selected AMG applications, limited gasket repair | 7,500–9,500 | Exact engine and bank; not a full V8 or both-head price |
| Selected Vito/Sprinter, reusable cylinder head | 4,500–6,200 | Engine, injector removal, head condition and van configuration |
The repair ranges assume a gasket, new head bolts, normal removal and refitting labor, oil/filter, coolant, and post-repair checks. The diagnostic row is separate. Possible additions include cylinder-head pressure testing or machining, estimated at AED 600–1,800 when suitable, and repair of the original cooling fault, which can range from about AED 350 for a minor hose-related repair to AED 4,200 or more for major components and labor. A replacement cylinder head is quoted only after the engine, VIN, availability, and condition are confirmed. Both-bank and severely damaged engines may exceed these ranges. Your written estimate should state whether 5% VAT is included and show the total payable before approval.
Get a quote for your engine
Send your model, year, mileage, symptoms, and any overheating history. A dashboard photo helps; the VIN can confirm the engine and parts before ordering. Ask for the diagnostic charge first, then an itemized repair estimate showing parts, labor, fluids, outside machine work, VAT, and any optional or additional work separately.
Confirm before dismantling
What the inspection needs to establish
Mercedes Star diagnostics supplies fault codes and live data. It does not, by itself, prove a head gasket has failed. We combine the relevant checks and explain what they show.
- Where the coolant is goingCheck the cooling circuit, cap and accessible external leaks. A pressure drop shows leakage, but does not identify the gasket by itself.
- Whether combustion leakage is presentA combustion-gas check and appropriate compression or cylinder leak-down testing can help identify internal leakage. A cracked head can give similar findings.
- Whether another part is responsibleAssess the oil cooler, ignition components, and other relevant causes. On equipped diesel engines, an EGR cooler may need evaluation before blaming the head gasket.
From approval to handover
What happens during the repair?
The initial inspection may justify removing the head, but some damage is visible only afterward. Agree on that investigation stage and its cost before dismantling. Any revised repair recommendation should be explained before additional work.
Inspect the removed head
Check for cracks, distortion and damaged sealing surfaces. Confirm whether the head is reusable or needs specialist assessment.
Prepare and reseal
Use the correct gasket and bolts with engine-specific surface preparation, tightening sequence and timing procedure. Replace disturbed seals as required.
Correct the original cause
A failed pump, thermostat, leak or other overheating cause needs its own repair. A new gasket cannot compensate for an unresolved cooling fault.
Refill and verify
Use the specified fluids and bleeding method. Check leaks, temperature behavior, engine operation and relevant test results before handover.
Genuine and matched supplier parts
Ask for the gasket brand and part number on the estimate. Genuine Mercedes parts and suitable supplier alternatives must match the exact engine. Gasket material or an AMG label alone does not establish compatibility.
Only replace extras when needed
Timing chains, guides, pumps, thermostats and ignition parts are not automatically included. If wear or a fault is found, ask what is necessary now and whether shared access reduces additional labor.
Three ways the quote can differ
Typical Mercedes head gasket replacement job estimates
The following are hypothetical planning scenarios, not completed customer jobs. Each assumes testing confirms a gasket leak and the head can be reused. Turnaround starts after approval and parts availability; machine-shop queues or further damage can extend it.
Typical estimate · 2015 C200
Four-cylinder gasket replacement
AED 4,200–5,800Complaint: Coolant loss with rough cold starts. Pressure, combustion-leak and cylinder checks are needed before removal.
Assumed work: One matched gasket, new bolts, disturbed seals, oil/filter, coolant, refitting and checks. No cracked head or timing-chain replacement.
Planning time: About 3–5 working days. Head assessment and parts supply can extend this.
Typical estimate · 2017 GLC300
Gasket repair after overheating
AED 5,800–7,500Complaint: Overheating history and repeated coolant loss. Check the cooling system and internal leakage before deciding on dismantling.
Assumed work: Gasket and bolts on a reusable four-cylinder head, associated seals, fluids and testing. A failed cooling component or head machining is extra.
Planning time: About 4–6 working days, subject to head checks and any separate cooling repair.
Typical estimate · 2018 C43
One-bank V6 gasket repair
AED 7,500–9,500Complaint: Persistent misfire with coolant loss. Confirm the engine, affected bank and leakage through appropriate cylinder tests.
Assumed work: One affected head only, matched gasket, bolts, associated seals, fluids and final checks. Both-bank work, turbo faults and internal damage are excluded.
Planning time: About 5–7 working days. Restricted access, parts or head damage may extend the job.
Warranty duration is not assumed for these estimates. Ask for the selected parts warranty, labor coverage, exclusions, and any mileage limit in writing before approval.
Clear findings, clear choices
Know what you are approving
Our engine inspection combines Mercedes Star diagnostic data with mechanical checks. Your quote should distinguish gasket replacement from head work, cooling repairs, and any wider engine damage.
MercGarage offers warranty-backed parts and installation options. The applicable coverage depends on the selected repair and parts; have the terms recorded on the quotation and invoice.
Aftercare matters. Follow the vehicle-specific coolant schedule and any repair follow-up instructions. A cold coolant-level recheck may be recommended after the first heat cycles. Report new coolant loss, unusual temperature behavior, warning messages, or misfires promptly. No repair can guarantee that an unrelated future cooling fault will never occur.
Compatibility changes the work
Your engine matters more than the model name
- Four-cylinder models: Layout and generation change access, timing work and gasket selection. A C200 badge does not identify one engine for every year.
- V6 and V8 engines: Identify the affected bank. One-head estimates must not be treated as both-head prices.
- Diesel and van applications: Injector removal, gasket specification and other possible coolant leaks can change the work.
- Hybrid versus electric: A hybrid’s combustion engine can require head gasket work. A fully electric Mercedes has no combustion-engine head gasket.
Send the VIN if the year or engine is uncertain, especially on an imported vehicle or one with a replacement engine.

Before you book
Head gasket repair FAQs
Answers about diagnosis, costs, downtime, and what to approve.
Can I drive with a suspected head gasket leak?
Avoid driving if it is overheating, losing coolant quickly, producing steam, or running severely rough. Stop safely and arrange recovery. If there is only an unexplained symptom, call for advice rather than assuming a short trip is safe.
Does white smoke prove the gasket has failed?
No. Brief condensation, fueling problems and other faults can look similar. Persistent white exhaust combined with coolant loss justifies testing, but the gasket, cylinder head and other possible leak sources still need to be distinguished.
Will head gasket replacement fix overheating?
Only if the gasket is part of the problem and the cause of overheating is also corrected. A leaking hose, faulty thermostat, water pump or radiator can require a separate repair. If testing finds an external leak, coolant leak repair may be the appropriate first service.
Why can the quote change after head removal?
Cracks, distortion or internal damage may only become clear after dismantling and testing. Agree on the cost of that investigation first. Any extra head work, parts or engine repair should be quoted for approval before proceeding.
Can a sealant replace this repair?
A pour-in product cannot restore a distorted head, damaged gasket joint or worn engine. It should not be used as a reason to keep driving an overheating vehicle. Tell the technician if any sealant has already been added, because it can affect investigation and cleaning.
How long will my Mercedes be in the workshop?
The example repairs allow roughly 3–7 working days after approval and parts availability. This is a planning allowance, not a promised completion time. Head testing, machine work, difficult disassembly or additional faults can take longer.
Do you replace both head gaskets on a V-engine?
Not automatically. Testing, engine-specific requirements and the condition of both banks determine the recommendation. The estimate should state which head or heads are included and explain any reason to work on both.
What is included in the warranty?
Ask for the coverage on the specific parts and labor quoted, including its duration, any mileage limit, exclusions and claim process. We do not assign an assumed warranty period to a hypothetical repair estimate.
Can I replace the gasket myself?
This is specialist engine work involving timing, surface checks and controlled assembly. An incorrect repair can cause major damage. Owners can safely record symptoms and service history; dismantling and pressure testing belong in an equipped workshop.
