I have a 93 civic with a 1.6 and the other day it overheated. I let it cool and filled it up with water until i got home drained the water and filled with 50/50. now every time i go somewhere and the motor warms up the coolant bubbles into the overflow and on the ground. I took the cap off the radiator and noticed that lots of air is being pushed into the coolant system. do u think i have a bad head gasket? no oil and water mix. Sometimes the heater goes cold and there is little steam coming from exhaust. I live in Oregon which is a very humid environment. the fan works and i bought the car used with a new radiator. after a few months i noticed that someone had put that crap sealant stuff in the cooling system. The hose for the top of the radiator gets really hot and the one on the bottom to the thermostat doesn't get as hot. any help?

 

Your head gasket is blown.

 

dont listen to him, and also check your oil dipstick is it milkey?? if then the head gaskets blown. open your raidator cap and start the car let it boil then put the cap on while its bubling. call me at 530 348 2135 my name is myles describe it to me on the phone.

 

now im having the same issue and just had the Head gasket replaced.
When i drive my car around and let it heat up the temp gauge only goes up about a quarter of the way and when i stop and im letting it idle its steaming very bad out of just the overflow so i dont know what to do.

 

Replace your overflow.. No probs with radiator or gasket bleed the system

 

Sounds like an air pocket in the system

 

so i bled the system and now its better just running warm because of fan not working. Than you very much
