nope, even if you are driving at khunjerab top a normal car temp guage operates in middle.
a car not reaching optimum level introduces problems with the passage of time as the block metal requires optimum temperature to operate efficiently.
i might be completely wrong but thats the sort of bit i have read/heard and believe in.
thats no brainer though, i guess bleeding of cooling system shall solve it in a jiffy.
the idle rpm of car also gets confused.
pouring in coolant without bleeding air usually causes this issue.
