Hi Im David, thanks for visiting the site, with the engine at operating temp make sure the upper and lower radiator hoses are equally hot.

They are connected, no leaks. Issue was the fan modulator and it has been replaced. The fan does not come on some times when the ac is running and the car gets hit. Temps come back to normal if I turn the heater on

Did you see my additional comments.

ok, then it sounds like you have air trapped in the system. havs the system been bled?

No, have not been bled
Customer: replied 1 month ago.
It got few times over the past 2 years due to the fan issues, could that hurt the thermostat ?

you may want to do a coolant system flush and then bleed all of the air out when you are through

the thermostat could be getting gunked up and sticking......

Customer: replied 1 month ago.
Ok, you think it is related to air in the system and not electrical?

yes, I believe its nothing electrical and has to do with air in the system, a possible sticking thermostat and a needed system flush.
