Quick answer
A Coolray that runs hot is most often losing coolant or not moving heat out of the 1.5TD turbo engine fast enough, through a leak, a sticking thermostat, a tired water pump or a clogged radiator. If the temperature warning turns red, pull over safely, switch off and let the engine cool before you touch anything. Do not open the expansion-tank cap while it is hot. Send ShipMyPart your VIN and we can source the cooling parts a qualified workshop identifies.
Which Coolray this page is about
| Published by Geely UAE | Why it matters when the engine runs hot |
|---|---|
| 1.5TD turbocharged petrol | A small turbo engine makes a lot of heat for its size, so the cooling system has little margin. |
| 128 kW (174 HP) / 290 N·m | High output under load adds heat on long climbs and fast motorway runs. |
| 7DCT gearbox | Covered on our separate Coolray gearbox page. |
| Model year, engine code, driven wheels | Not stated on the page; earlier Coolrays may differ, so we confirm by VIN. |
| Coolant type and capacity | Not verified by ShipMyPart. |

How overheating shows up on a Coolray
| Situation | What drivers tend to notice |
|---|---|
| Crawling in traffic with the A/C on | Temperature reading creeps up, radiator fan runs loudly for long periods, cabin air turns less cold. |
| Motorway or uphill under load | Gauge or warning rises, engine may feel weaker as it protects itself. |
| After parking | Sweet smell, hissing or a wet patch under the front of the car. |
| Cold morning start | Heater slow to warm or the reservoir level lower than last week. |
Possible causes on the 1.5TD
Possible causes include:
- Coolant loss from a split hose, a loose clamp or a weeping joint, which lowers the level until the engine can no longer shed heat.
- A thermostat that sticks closed or opens late, holding coolant back from the radiator.
- Water pump wear: a leaking seal or a worn impeller that circulates too little coolant.
- A radiator blocked outside or inside: dust and insects packed between the fins, or deposits inside the core.
- A cooling fan or fan control fault, which shows up mainly at low speed.
- A faulty temperature sensor that misreports, so the gauge and the real temperature disagree.
None of these can be confirmed from symptoms alone; a pressure test and a scan are needed.
Which cooling part a workshop may suspect, and why
| Coolray part | Clues that point a workshop towards it |
|---|---|
| Radiator | Fan is running yet the reading still climbs at low speed; fins visibly packed, or seepage at the plastic end tanks. |
| Water pump | Coolant traces on the engine front, a bearing rumble, or a heater that is slow to warm although the level is correct. |
| Thermostat | Temperature rises soon after a cold start on the motorway, while the radiator side stays cooler than expected when tested. |
| Expansion tank / reservoir | Hairline cracks in the plastic, a cap that no longer seals, a level that falls with no drips under the car. |
| Hoses and pipes | Rubber that is swollen, soft or cracked, or dried crust where a clamp sits. |
| Temperature sensor | An erratic gauge that does not match how the engine behaves, with a stored fault code. |
Look, listen, smell: owner checks on a cold Coolray
Before anything else: wait until the 1.5TD has cooled right down. The expansion-tank cap must stay closed on a warm engine, because the system is pressurised and coolant can spray out scalding.
Look at the translucent reservoir with the car parked level and mark where the coolant sits relative to MIN and MAX; repeat in a few days. Glance under the nose for drips, and at the grille for a mat of dust or a stray bag.
Listen with the engine idling and the A/C switched on: as the temperature reading rises, the radiator fan should cut in audibly.
Smell around the front wheels after a drive; a syrupy odour often means coolant is escaping somewhere.
Red warning? Stop. Recurring? Get it diagnosed
A red coolant warning, visible steam or a needle that keeps rising are all reasons to leave the road at the first safe spot and turn the engine off. A small turbo engine that keeps running while boiling risks a failed head gasket and a cooked turbocharger, both far costlier than the original fault. If it overheats again after cooling, call recovery instead of driving on.
Less urgent signs still deserve a qualified workshop: needing to add coolant every week or two, a fan that never seems to start, cold air from the heater while the gauge reads high, or a mayonnaise-like deposit under the oil filler cap. Expect a pressure test and a scan for stored codes.
Coolray cooling in UAE summers
The Coolray is a compact crossover, so its radiator, A/C condenser and charge-air cooler share a small space behind the grille. In July and August, long idling on Sheikh Zayed Road or in school-run queues with the A/C at full gives that stack very little cooling airflow. Fine sand from desert-edge roads can also pack into the fins. A quick visual check of the grille area before summer and after a dusty week is worthwhile.
Getting Coolray cooling parts through ShipMyPart
Cooling repairs on the 1.5TD rarely involve a single item: a water pump usually needs its gasket, a thermostat its housing seal, and a split hose may come with new clamps. Ask the workshop for the full list, then send it to ShipMyPart with your Coolray VIN. We work out each part number for your exact car, check the match, send you one quote and deliver within the UAE. The Geely Coolray coolant guide explains what is and is not confirmed about the coolant.

Frequently asked questions
Why does my Geely Coolray overheat only in traffic?
Low-speed heat usually points to airflow: possible causes include a radiator fan that does not run, a fan control fault or fins blocked with dust. Have it checked before summer.
Can I keep driving a Coolray with the temperature warning on?
No. Stop safely, switch off and let it cool. Continuing may damage the engine and the turbocharger.
Is it safe to open the coolant cap to check the level?
Only when the engine is completely cold. A hot system is pressurised and can spray scalding coolant.
Which coolant does the Coolray 1.5TD use?
ShipMyPart has not verified the coolant type. Check the owner's manual or send us your VIN.
Can a bad thermostat cause Coolray overheating?
Yes, a thermostat that sticks closed can stop coolant reaching the radiator. A workshop can confirm it with a temperature check.
How do I order the right cooling part for my Coolray?
Send us the VIN and the workshop finding. We match the part to your car and deliver in the UAE.
