My 1991 Accord is acting overheating problem over 40 MPH. The temperature
gauge rises to almost red indicator at highway speed, over 55MPH. I already
changed the thermostat and bleed the coolant air bubbles. The symptom
happens at hot environment; I notice the coolant boiling in the reservoir
with many bubbles and create a very high pressure to push the coolant out of
reservoir. I am wondering can anyone suggest the solution to solve this
problem.



Thanks
