Not sure whether is related to your issue or not. There's 2 spec of thermostat for campro in market. If not mistaken one is 78°C and another is 84°C. If you installed the one with higher opening temperature, i imagine your fan will run longer to dissipate heat between each thermostat open-close cycle. The changes in your fan behavior might warrant a coolant level check, water pump check or radiator efficiency check.
However this doesn't explain your cold start issue. Have you taken a look at your throttle body and consider a cleaning of it?
On the side note, there is a user in Facebook that run his Gen2/Persona without thermostat. But would this contribute long term damage to engine due to non optimum engine temperature remains unknown.
My is 78°C which claimed as Original from Proton, but i do notice the washer is not. RM5 for that.
Now the fan behavior is back to normal. I even notice spin also not that loud, compared to before is like full speed.
Ya, cold start drive issue normally is throttle body. I've clean it 2 years ago, just wonder why before i change thermostat no such issue, after change only obvious?
Or due to during change take out the intake filter let it run and naked cause the dirt in? But is just for 10 ~ 15 minutes only, shouldn't be an issue.
Anyway, I will monitor first. As purposely sent to clean will cost another RM100
