Get a clear diagnosis before spending on major engine work at our auto garage in Dubai. We inspect overheating, smoke, oil loss, coolant loss, misfires, knocking and low compression, then explain whether a focused repair, rebuild or replacement makes better financial sense.
The next step depends on what the car is doing now. Our car computer diagnostic service can support faults involving warning lights, sensors and control systems. A short description of the symptom is enough to begin. You do not need to identify the failed part yourself.
Do not keep restarting a severely overheated, oil-starved, knocking, or water-ingested engine. Repeated attempts can increase internal damage and the final repair cost.
These are market-based estimated ranges, not fixed quotes. The final amount depends on the vehicle, engine layout, test results, parts choice and damage found after dismantling. We confirm the work and customer-payable total in writing before repair. Estimates below include typical labor and relevant basic consumables. VAT treatment is confirmed on the written quote.
| Engine service | Estimated total | Typical scope | Usual timing |
|---|---|---|---|
| Computer scan and engine inspection | AED 150 to 350 | Fault-code scan, visual checks and initial test plan. Workshop inspection is currently free. | 45 to 90 minutes |
| Ignition or minor running repair | AED 350 to 1,800 | Diagnosis plus items such as plugs, a coil, a sensor, hose or cleaning when confirmed faulty. | Same day in many cases |
| Oil leak repair | AED 450 to 3,500 | Seal or gasket replacement, cleaning, fluids and leak recheck. Accessibility changes labor substantially. | 4 hours to 2 days |
| Cooling-system and overheating repair | AED 550 to 4,500 | Pressure testing and the confirmed radiator, thermostat, pump, hose or related repair. | Same day to 3 days |
| Head-gasket or cylinder-head repair | AED 2,800 to 8,500 | Strip-down, head assessment, gasket set, bolts, machining where needed, fluids and testing. | 3 to 7 working days |
| Engine rebuild or overhaul | AED 6,500 to 22,000+ | Measured dismantling, machining as required, internal parts, seals, reassembly and testing. | 7 to 20 working days |
| Used or remanufactured engine replacement | AED 5,500 to 30,000+ | Compatible engine, removal and installation, fluids, adaptation and final checks. Unit cost varies widely. | 3 to 10 working days after sourcing |
Why the range is wide: a four-cylinder engine with easy access costs less to dismantle than a turbocharged V6 or V8. Cylinder-head condition, block damage, machining, turbo contamination, parts availability and whether related cooling faults must be corrected all affect the total. Equivalent repair scope can be 65% to 70% lower than agency pricing, depending on parts and vehicle.
Best when testing identifies a contained fault and the engine’s core mechanical condition is healthy. Common work includes ignition repairs, injector service, intake leaks, cooling components, oil seals, timing-related repairs and cylinder-head work. This option normally preserves the original engine and avoids unnecessary dismantling.
Choose it when: compression and oil pressure are acceptable, contamination is limited and the repair cost is reasonable compared with the car’s value.
Best when the original engine is valuable, compatible replacements are uncertain, or measured internal wear can be corrected properly. The engine is dismantled, cleaned and measured. Required bearings, rings, seals, gaskets and damaged parts are replaced, while machining is completed only where measurements require it.
Choose it when: the block and main castings are usable and there is a defensible parts and machining plan.
Best when the existing unit is seized, cracked, heavily overheated or uneconomical to rebuild. A replacement may be used, remanufactured or new. Compatibility, engine code, electronics, accessories, condition and supplier terms must be checked before purchase.
Choose it when: a traceable compatible unit offers a better total cost, timeline and risk than rebuilding the damaged engine.
Switch off safely. Do not keep restarting an overheated, oil-starved or water-ingested engine.
Monitor the gauges and fluid levels. Avoid long trips and hard acceleration until the cause is checked.
| What you notice | Possible causes | How serious? | Useful next check |
|---|---|---|---|
| White exhaust smoke and coolant loss | Head gasket, cracked head, coolant entering a cylinder or, on some engines, another coolant-fed component | High | Cooling pressure test, combustion-gas check and compression or leak-down testing |
| Blue smoke or high oil use | Turbo seals, valve-stem seals, piston rings, PCV fault or external leak reaching hot parts | Medium to high | Leak inspection, PCV and turbo checks, spark-plug reading, compression and leak-down tests |
| Knocking or low oil pressure | Low oil level, wrong oil, worn bearings, blocked pickup, oil pump fault or internal damage | Critical | Stop engine, verify oil level, measure mechanical oil pressure and inspect the filter or sump |
| Misfire and rough idle | Plug, coil, injector, air leak, carbon buildup, low compression or timing issue | Varies | Scan live data, isolate the cylinder and test ignition, fueling and compression |
| Overheating | Leak, fan issue, thermostat, water pump, restricted radiator, trapped air or internal sealing fault | High | Pressure test, fan activation check, temperature comparison and coolant-circulation assessment |
| Loss of power | Boost leak, turbo fault, fuel delivery, blocked exhaust, sensor error, timing deviation or low compression | Varies | Scan under load, smoke-test intake, review fuel and boost data, then test mechanical condition |
The same symptom can begin in different areas. These six inspection zones help explain why testing comes before a repair or parts decision.
We record when the symptom happens, review warning lights and inspect oil, coolant, leaks, belts, hoses and visible damage. A controlled road test is used only when the car is safe to drive.
Depending on the fault, checks may include diagnostic scanning, live data, cooling pressure, smoke testing, fuel pressure, mechanical oil pressure, compression, cylinder leak-down, borescope inspection or oil-filter examination.
We compare the findings with the vehicle’s engine design and fault history. Major dismantling is recommended only when external tests justify it. You receive the options and estimated total before approving work.
A lean-mixture code can come from an intake leak, weak fuel supply or incorrect sensor reading. A cylinder-misfire code does not automatically mean a coil is defective. Replacing the named part without testing the circuit and mechanical condition can waste money and leave the original problem unresolved.
Replacing only the head gasket can fail if a warped head, cracked casting, blocked radiator, weak fan, damaged water pump or earlier coolant contamination is missed. We check the cooling system and the consequence of the overheat together.
White vapor can be normal condensation, while persistent white smoke with coolant loss points toward internal coolant entry. Blue smoke can come from turbo seals, valve seals, rings or a crankcase-ventilation fault. Testing determines which repair is justified.
A failed pulley, tensioner, compressor or flywheel can sound like internal engine damage. Listening tests, belt isolation and oil-pressure checks help prevent an unnecessary rebuild or replacement.
Trust should come from findings you can understand, a scope you can compare, and a decision you control. Our car repair advice explains how to compare evidence and written estimates. A fault code, unusual noise, smoke color, or price estimate is a starting point, not proof that an expensive part must be replaced.
The inspection starts with what the car is doing, then uses the relevant checks to narrow the cause. Depending on the fault, that may include live data, pressure testing, compression, leak-down, borescope images, smoke testing, oil-pressure measurement, or inspection for contamination and metal debris.
02 / ExplainBefore major work begins, the proposed repair should identify the suspected or confirmed fault, the parts route, the expected labor, the estimated customer-payable total, and anything that cannot be known until dismantling. Repair, rebuild, and replacement options are compared when more than one route is sensible.
03 / ApproveIf dismantling exposes additional damage, the new finding and revised cost are discussed before that extra work proceeds. A conditional finding is described as conditional. It is not presented as certainty simply to make the first quote look complete.
No blind promise: we can give a useful estimate from the model and symptom, but the final repair decision follows the inspection. If the evidence does not justify major engine work, the recommendation should not assume it.
The following illustrative entries show how scope changes the total. They are not claims about completed customer vehicles. The exact amount for your car follows inspection and parts confirmation.
Work: overheating diagnosis, thermostat and water-pump replacement, coolant refill, bleeding and temperature verification.
Parts: quality replacement pump and thermostat, subject to brand availability.
Example total: AED 1,850.
Work: oil-leak diagnosis, valve-cover assembly and gasket replacement, cleaning, oil-level correction and leak recheck.
Parts: complete replacement cover with integrated ventilation components.
Example total: AED 2,950.
Work: engine removal, measured overhaul, bearing and ring service, gasket set, required machining, fluids and installed testing.
Parts: internal parts selected after measurement and inspection.
Example total: AED 14,800.
Call or WhatsApp with the model and a short description. Choose a workshop visit, free pickup and delivery, or ask whether an on-site inspection is suitable.
We perform the relevant checks and explain the evidence. The quote separates the intended repair, parts choice, labor and any work that depends on dismantling.
No major repair begins until you approve the scope. If dismantling reveals additional damage, the revised finding and cost are discussed first.
Specified tightening procedures, sealing surfaces, fluids and timing references are followed for the approved work. Related components are checked while access is available.
Final checks may include leak inspection, temperature monitoring, oil-pressure confirmation, fault-code review, adaptation and a controlled road test.
You receive a clear summary of the completed scope, the parts route used, and practical running-in or follow-up guidance when it applies. Ask any remaining questions before collection or free delivery.
Direct-injection petrol engines can develop injector, high-pressure fuel, carbon, ignition and crankcase-ventilation faults. Turbo engines also need boost-leak, lubrication and charge-air checks. When a turbo fails, the intake, intercooler, oil feed and exhaust side must be assessed so debris or restricted oil supply does not damage the replacement.
Timing-chain noise, variable-valve timing faults and oil-pressure issues should be tested early. A timing code can reflect a sensor or control issue, but it can also warn of mechanical wear that should not be ignored.
Diesel power loss or smoke may involve injectors, boost control, EGR, particulate filtration, compression or fuel pressure. Diagnosis should separate an emissions-system restriction from an internal engine fault before dismantling.
Hybrid vehicles require safe isolation awareness and model-specific procedures because the combustion engine operates with high-voltage systems and may start automatically. Engine-related work must consider cooling loops, electronic controls and hybrid operating conditions.
A targeted diagnosis usually costs far less than replacing multiple parts by guesswork. Ask what the test will prove and how it changes the repair decision.
For rebuild and replacement options, compare the engine unit, machining, labor, fluids, seals, programming, related cooling work and follow-up checks. A low unit price is not the installed total.
Genuine, OEM-quality, aftermarket, used and remanufactured parts have different costs and risks. The suitable choice depends on the component, vehicle value, intended ownership period and supplier support.
DIY checks should be limited to safe basics such as noting warning lights and checking fluid levels when the engine is cold and the owner’s manual permits it. Internal timing, compression diagnosis, overheating teardown and engine lifting require workshop equipment and technical procedures.
A rebuild becomes a serious option when testing confirms internal wear or damage across multiple cylinders, bearings, pistons, rings or sealing surfaces. Compression, leak-down, oil-pressure, borescope and dismantling measurements guide the decision. A single failed external component does not justify an overhaul.
We can provide an estimated range after you share the model and symptom. A final price usually requires inspection because smoke, overheating, misfire and oil loss can have very different causes. The written quote confirms the scope before work begins.
It depends on the condition and traceability of the replacement, compatibility, installed total and the rebuild potential of your original unit. A cheaper used engine can become expensive if its engine code, electronics or condition are not checked. We compare both routes when they are viable.
A typical rebuild may take 7 to 20 working days. The timeline depends on dismantling findings, machining, parts availability and reassembly testing. Simpler cylinder-head work may be faster, while uncommon or performance engines can take longer.
We assess petrol, diesel, turbocharged and selected hybrid vehicle engine concerns across many European, Japanese, American, Korean and other makes. The exact repair route depends on model-specific tooling, information, parts and the engine’s condition.
Yes. Free pickup and delivery are available. Tell us if the engine overheated, lost oil pressure, makes a heavy knock or cannot run, so the vehicle can be handled safely. Do not restart a severely damaged engine simply to move it.
The workshop inspection starts with the complaint, warning lights, fluid condition, leaks and basic operating checks. Additional diagnostic tests depend on the symptom. We explain any paid dismantling or specialist testing before it is carried out.
Our dedicated inspection van can help assess some problems on-site. Major engine repairs, rebuilds and replacements normally require workshop lifting, measuring, cleaning and testing equipment. The first assessment determines the safe next step.
Send your car model and the symptom. We will help you choose a workshop visit, free pickup and delivery, or a suitable on-site inspection. You do not need to diagnose the fault before contacting us.
