Summer puts extra load on the cooling system. A few simple checks keep the temperature gauge steady.
In this article
- Check the coolant
- Look at the hoses and fan
- If it overheats
Check the coolant
Look at the level when the engine is cold. A low level suggests a leak, and a sweet smell points the same way.
| Warning | Meaning | Action |
|---|---|---|
| Gauge rising | Cooling issue | Pull over safely |
| Steam from hood | Coolant boiling | Stop, wait |
| Sweet smell | Coolant leak | Inspect |
| Warning light | Low coolant or heat | Stop |
Intervals and costs are typical ranges. Your owner’s manual comes first.
Look at the hoses and fan
Squeeze the hoses to check for softness or cracks. Make sure the radiator fan turns on when the engine warms up.
Heat is patient and relentless.
If it overheats
Turn off the A/C and turn on the heater to draw heat away. Pull over, switch off and wait before opening the hood.
Do it in this order
- Check coolant when cold
- Inspect hoses
- Test the fan
- Carry spare coolant
Practical tip
Do not open the radiator cap while the engine is hot. Pressurized coolant can cause serious burns.
Bottom line
A quick under-hood check before summer trips can prevent a roadside stop.
Specifications, prices and rules change. Confirm current details with the manufacturer or the relevant authority before you buy or repair.
