These engines are stated to run between 70 - 100 degrees.
Mine used to have similar fluctuations, but seems to have settled. Hopefully I wont see that return in colder months.

Temps don't seem too bad. have you checked exterior of rad for blockage? They are pretty cheap...

Hi,yes I checked mainly everything before posting question other here lol

But radiator wouldn’t be a case because it’s cooling down not overheating . Temperature not supposed to fluctuate it’s suppose stay steady and coolant supposed to warm up to working temperature 90-95C while vehicle parked up not only when driving on motorway
