Thanks for reply
The readings were correct there is no mistake
Remember I told u the car heater work normally because the car is having secondary water pump which circulate coolant through heater core when In used, from water pump one hose going to aux water pump, the new mechanic was way too experienced he find out my heater is blowing very very hot air when In used because engine water pump is not doing it s job when at idle and that s why lower hose connected to block is more hotter then upper. I replaced the water pump and now my fan also start at 87c when thermostat open.
Before my fan start 95c coz ecm is confuse with fluctuation coolant and the mechanic find out this on oil cooler by heat gun temperature was coming low and high up and down.
