When I'm driving down the highway it overheats and the heater stops blowing out hot air and it starts just barely blowing coldthen when I got stopped at a blue steam out the top when I took the cap off

Temperature rosed to 3/4 the temperature gauge.

Had the mechanic shop fix our ac, since then it will randomly overheat or my gas sensor will not read properly (That was stuck and is temporarily fixed until we can get it to the shop) The overheating has caused Buffy (Our Civic) to be undriveable.

Reservoir coolant water dried up when AC works for close to 2 hours

My vehicle overheats anytime I embark on over an hour journey. Even on a short distance trip, it rises once I turn on my Air Conditioner for up to 20 minutes duration

I just bought a used 2004 Honda civic ex coupe and it started overheating. The previous owner said that he replaced the radiator, timing belt, water pump, etc. And gave me the old timing belt as proof. I replaced the thermostat to see if that was the issues but it was not. When I open the radiator cap to add coolant it is never full. Any ideas?

Air-conditioning is turned off while driving

Just bought a 1998 coupe civic dx model with a d16y7 ? Manual 1.6l on my way home I parked the vehicle noticed bubbling sound coming from under hood figured coolant ? Two days later I checked fluids radiator lost coolant and oil down to my knuckle on radiator cap with oil. Rinsed out overflow it was full too with engine oil. Refilled coolant, hoses have probably too much pressure in it. Radiator fan has yet to turn on.

I changed the radiator cause it had a crack in it and was obviously overheating. I changed the hoses and thermostat as well. The fan stopped working so I changed the relay. Every three days I top off the coolant in the morning because if I don't on the third day it will start overheating but then will go back down. It fluctuates. When I put fluid in even when cold like in the morning I notice lots of pressure built up. There's no oil in the over flow fluid. It looks pretty clean.

Everytime i stepped-up the gas to reach over 65/kmph, the heat sensor meter starts to rattle back and forth but the engine does not overheat. What's the problem?
