Quick answer
If the temperature gauge on a Haval Jolion climbs or a red coolant warning lights up, pull over somewhere safe, switch the engine off and let it cool; do not touch the radiator or expansion-tank cap while the engine is hot. On the Jolion's 1.5-litre turbocharged petrol engine, possible causes include coolant lost through a leak, a thermostat that does not open fully, a tired water pump, a cooling-fan fault or a radiator face clogged with dust. A qualified workshop should confirm the cause before parts are bought, and ShipMyPart can then source matching parts from your VIN.

Warning signs on a hot Jolion
| What you notice | What it can indicate |
|---|---|
| Needle creeping up while queuing at lights, settling once moving | Weak airflow at low speed: fan, fan control or a dirty radiator face |
| Red coolant-temperature symbol or a cluster message | Real overheating until proven otherwise; stop and switch off |
| Sweet, syrupy smell near the front wheels or through the vents | Coolant escaping from a hose, joint, tank or heater circuit |
| Expansion-tank level a little lower every week | A slow leak that may only drip when the system is pressurised |
| Engine feels flat, even in Sport mode | Engine management reducing output to protect the turbo engine |
| Heater blowing cool while the gauge reads high | Low coolant or trapped air in the circuit |
What can make the 1.5T run hot
Possible causes include the following, grouped by what goes wrong:
- Coolant escaping. Rubber hoses harden with heat cycles, clamps loosen and plastic tank seams can crack. Even a small loss can lift the gauge on a compact engine bay like the Jolion's.
- Coolant not circulating. A thermostat stuck partly shut keeps hot coolant away from the radiator; a water pump with a worn impeller or a leaking seal moves less of it.
- Heat not leaving the radiator. The radiator, A/C condenser and turbo intercooler are stacked behind the grille, and dust, sand or insects packed between them cut airflow. A fan or fan-relay fault has the same effect at low speed.
- Misleading readings. A faulty coolant-temperature sensor or connector may show a false high reading or upset fan control.
- Extra heat from the turbo side. Hard driving in Sport mode on hot days raises engine heat; a leaking intercooler pipe usually shows as lost power rather than overheating, but it is worth inspecting at the same time.
A head-gasket leak can also push gas into the coolant and cause overheating. Only a workshop test can confirm that, so do not assume it.
Jolion cooling parts and their jobs
| Part | Role in the circuit |
|---|---|
| Radiator | Sheds engine heat into the air passing through the grille |
| Water pump | Pushes coolant round the block, head and radiator |
| Thermostat | Opens the radiator path once the engine has warmed up |
| Expansion tank / coolant reservoir | Holds the reserve and the pressure cap; shows the MIN and MAX marks |
| Hoses and pipes | Carry coolant between parts; aged rubber and clamps are frequent leak points |
| Temperature sensor | Feeds the gauge and the fan logic |
| Intercooler | Cools the turbo's charge air and shares the airflow at the front |
| Belts and pulleys | Drive engine ancillaries; check on your engine whether the pump is belt-driven |
Owner checks with a cold engine
Leave these until the Jolion has stood long enough for the bonnet to feel cool:
- Find the translucent expansion tank and see where the coolant sits against the MIN and MAX marks. Look only; keep the cap closed.
- Run a hand-held torch along the hoses you can see for wet patches, white or coloured crust, or a swollen, soft section.
- Look through the lower grille: a felt-like layer of dust or a mat of insects on the front cores is easy to spot.
- Check the ground where you park overnight for fresh spots under the engine.
- On your next drive, note whether the gauge rises in traffic, on the highway, or only with the A/C on full.
Never open a hot radiator or expansion-tank cap. The circuit is pressurised and coolant can spray out at scalding temperature.
How urgent is it? Three levels
Sort what you are seeing into one of three levels.
- Red: stop now. Needle at the top of the scale, the red coolant symbol, steam, or a knocking engine. Get off the road, turn the engine off and call for recovery. A small turbo petrol engine kept running hot can distort its cylinder head and ruin the gasket and the turbocharger.
- Amber: a workshop within days. Coolant that has needed topping up more than once, a reading that now settles higher than last month, cabin heat that fades while the engine is warm, or a creamy deposit under the oil filler cap.
- Watch: mention it at the next visit. Fans that keep running noticeably longer after switch-off, or a faint coolant smell after the hottest days.
For amber and watch items, a qualified workshop will usually pressure-test the circuit, confirm the fans switch on and scan the coolant-temperature data, which narrows the fault down before anything is ordered.
Jolion cooling in UAE city life
The Jolion sold here is a two-wheel-drive crossover, so most of its hard work happens on the road rather than in the dunes. The tough moments are summer afternoons: long waits at signals with the A/C working hard, multi-storey car parks where hot air recirculates, and short school runs where the fans barely rest. Wind-blown sand and construction dust settle on the condenser and radiator, so a look at the grille after a sandstorm is sensible. Owners who often drive in Sport mode on hot days put more heat through the 1.5T than those who stay in STD or ECO.
From workshop finding to the right Jolion part
- Get the finding. Ask the workshop to name the faulty part, for example the lower radiator hose or the thermostat housing.
- Send the VIN. Message ShipMyPart on WhatsApp or use the quote form with the VIN from the registration card. It tells us which Jolion output and build you have, which matters because cooling hardware may differ between versions.
- Receive a quote. We match the part to that VIN and reply with price and delivery time within the UAE.
Before the circuit is refilled, read the Haval Jolion coolant guide.

Frequently asked questions
Why does my Jolion only get hot when I am stuck in traffic?
At low speed the fans supply nearly all the airflow, so a fan or fan-control problem, or a radiator face blocked by dust, tends to show up in queues first. A workshop can confirm which applies.
Is it safe to keep driving with the temperature warning on?
No. Stop safely and switch off when the gauge is in red or a red warning shows. Driving on can damage the cylinder head, gasket and turbocharger.
When can I check the coolant in the expansion tank?
Only with a cold engine, and you can read the level through the tank without opening it. Never open the cap while the system is hot.
Do the 147 HP and 181 HP Jolions use the same cooling parts?
ShipMyPart has not verified that. Some parts may differ between versions, which is why we match every cooling part to the VIN.
Which coolant does the Haval Jolion take?
The coolant specification is not verified by ShipMyPart, so we do not quote it. Check the owner's manual or ask Haval UAE, and see our coolant guide.
Can ShipMyPart send Jolion cooling parts to me in the UAE?
Yes. Send the VIN and we source the radiator, pump, thermostat, tank, hoses, sensor or intercooler that matches it, with delivery in the UAE.
