Engine Cooling System Repair in Dubai
In Dubai’s extreme heat, your engine’s cooling system works overtime to keep temperatures under control. If it fails, even for a short time, you risk serious engine damage, breakdowns, and expensive repairs.
At our Al Quoz workshop, we specialise in complete engine cooling system diagnosis and repair for all makes and models – from daily commuters to European, luxury, 4×4, and performance cars.
What Your Engine Cooling System Does
Your cooling system keeps the engine at the right operating temperature by circulating coolant (antifreeze + water) through the engine and radiator. Key components include:
Radiator – releases heat from hot coolant into the air
Water pump – circulates coolant through the engine and radiator
Thermostat – regulates coolant flow based on temperature
Radiator fan & fan clutch – pull air through the radiator, especially in traffic
Hoses & clamps – carry coolant between components
Coolant / antifreeze – absorbs and transfers heat while protecting against corrosion
- Head Gasket – the gasket between the engine head and block; it ensures a tight seal between the two and keeps the oil, coolant, and combustion chamber separate
When any of these parts fail, your engine can start overheating very quickly.
Common Cooling System Problems We Fix
We handle every type of cooling system issue, including:
Engine overheating (especially in traffic or at low speeds)
Radiator leaks or clogged radiators
Faulty water pump (noise, leaks, or poor circulation)
Thermostat stuck open or closed
Coolant leaks from hoses, clamps, radiator, or expansion tank
Faulty radiator fans, fan clutches, or fan switches
Heater core leaks (foggy windscreen, coolant smell inside cabin)
Coolant contamination (oil in coolant or sludge in the system)
- Head gasket failure
Whether it’s a minor hose leak or a full cooling system overhaul, we diagnose the root cause before replacing parts.
Warning Signs You Need Cooling System Repair
Don’t wait until the engine completely overheats. Visit us if you notice any of these symptoms:
Temperature gauge rising higher than normal
Temperature warning light on the dashboard
Steam or smoke from under the bonnet
Coolant level dropping regularly
Puddles of green, red, or pink fluid under the car
Heater not working properly
Sweet smell from the engine bay or inside the cabin
White exhaust smoke
Engine feels weak, rough, or misfiring after an overheating incident
Continuing to drive with these symptoms can lead to warped cylinder heads, blown head gaskets, or complete engine failure. It’s always cheaper to fix cooling issues early.
Our Engine Cooling System Repair Process
When you bring your car to us for a cooling system issue, we follow a complete inspection, diagnostic, and repair procedure to identify the root cause — not just the symptoms.
1. Initial Inspection & Diagnostic Scan
We start with a thorough check of the entire system:
Visual inspection for leaks, damaged hoses, or loose clamps
Coolant level, colour, and condition check
Pressure test of the radiator, hoses, and expansion tank
OBD diagnostic scan for temperature sensor and fan control faults
Visual inspection for signs of head gasket failure (milky oil, coolant loss, or white smoke from exhaust)
2. Cooling System Pressure & Flow Tests
We then test how effectively your cooling system is circulating and holding pressure:
Radiator and expansion tank pressure tests to find hidden leaks
Thermostat operation and temperature control verification
Water pump inspection for leaks, bearing noise, or poor circulation
Radiator and heater core flow checks for internal blockage
Combustion leak test (CO₂ test) to detect exhaust gases in the coolant — an early sign of a blown head gasket
3. Repair & Replacement
Based on diagnostic results, we carry out the necessary repairs, which may include:
Radiator repair or replacement
Water pump or thermostat replacement
Radiator fan, relay, or sensor repair
Radiator hose and clamp replacement
Expansion tank repair or replacement
Head gasket repair or replacement, if overheating or coolant contamination has damaged the seal between the cylinder head and engine block
All repairs use genuine or high-quality OEM parts suitable for Dubai’s climate and driving conditions.
4. Cooling System Flush & Coolant Replacement
After repairs, we restore your system’s efficiency with a full service:
Flush the system to remove old coolant, rust, and sludge
Clean internal passages to prevent future overheating
Refill with manufacturer-approved coolant and bleed air from the system
Recheck operating temperature, fan activation, and pressure stability during a road test

Can an Overheated Engine Be Saved?
Many engines that have overheated once can still be saved if the car is stopped quickly and inspected properly. However, repeated overheating or driving the car while it’s boiling can cause:
Blown head gasket
Warped cylinder head
Cracked engine block
If your vehicle has overheated recently, it’s important to:
Get a cooling system check as soon as possible.
Perform a compression and leak-down test if we suspect internal engine damage.
Fix the root cause before continuing normal use.
We’ll always explain the condition honestly and show you evidence (photos/videos) where possible.
