2002 civic overheating
Hello, I have a 2002 Honda Civic EX sedan with 165k miles that is
overheating. It does not start overheating until after 30 mins of driving, the
radiator fans do work properly. I can turn the heat on full blast and return to
normal temperature , but will raise again immediately after i turn the heat off.
I checked for air in the system by attempting to bleed it through the coolant
temperature sensor located to the left of the valve cover, and no coolant
came out at all, even when the sensor was completely removed and system
was running at normal temp. Could that be a sign of a pressure issue (water
pump/blockage)? The person i purchased the vehicle from said the water
pump was recently replaced but i have no proof. Thanks in advance!!
