Civic Turbo overheating issue

[darthvader]

I need help from the experts as this is really making me nervous.

3 months ago I went to Hunza from Islamabad on my 1.5T. The 20 hour drive went perfectly fine, no issues. However on the way back near Babusar, I saw the coolant temperature needle at about 60% where it’s normally fixed at 40%. It kept fluctuating and I had to be really easy on the accelerator to manage to cross Babusar without it going too high.

Back to Islamabad. Local drive, drive to Lahore at speeds up to 180kph, no overheating.

Then today I went to Pir Chinasi. Again the same issue. The temperature needle went up to 60% when the car was on incline. However as soon as I eased on the gas, it immediately went down to 40. Then randomly it went up again in a matter of seconds.

The coolant level of the car is fine. I don’t think there are bubbles in the cooling system because the heater is working fine as well. What could be the issue?

Check your radiator fan, my guess is its not working when needed.

It is normal for all vehicles to slightly heat up on inclines, just take some break to let them cool down.
Your Civic is perfectly fine, just enjoy the ride.

Internationally, and especially in the US; the civic 1.5T has a habit of its intercooler heat-soaking in hot temperatures. I haven't heard of it overheating in hard driving, or on inclines; but its not too much of a stretch to think that the 1.5T would at least have moderate overheating in such conditions.
Your car probably has no issue, its just that turbo engines will always be more sensitive to overheating than N/A engines. You're saying yourself that your car is performing normally afterwards, so I don't think there's anything wrong with it.
It may be possible that you have a faulty sensor, but its unlikely.

just for peace of mind...connect scanner and pull data and see if theres any recorded abnormality there where Coolant Temp cross the threshold. however it could be minor due to stress on Turbo as it heats up.

not to mention turbo engines when used for continuous long hours heats up and can cause issues.. separate oil coolers could help bring down or rest in between drives . depends on how good company designed its cooling system

i assume it was turbo which makes it all happen. under stress or load where extreme power is required .

Hi, did your issue resolve?
Facing exact same situation with my Turbo 1.5

I just got the radiator cleaned and haven't faced this issue since

Where did you get it cleaned and what is the process?
