Hi, I have a 95 Civic LX. About a week ago i looked down and saw it was redlining as far as engine heat. I also noticed that about that time, i was no longer getting heat in the car but AC like cold air. The other night I replaced the Thermostat, flushed the system, pressure checked the radiator, checked head gaskets, and replaced the Radiator Fan Senson on the thermostat. Then as im delivering pizza's today (I work at papa johns ) shoom there it goes flying up again....I went and jumped the cooling fan cable so the radiator fan is constantly on but this doesnt seem to be helping (I dont think the fan was ever coming on anyway)....Any ideas would be GREATLY appreciated. Thanks

 

Damn.
I think you have plumbing issues, but not the kind you can easily fix...
I'm no mechanic tho.

 

Check the thermosensor for the radiator fan.

For future reference, post questions concerning '92 and newer Civics in the Civic/del Sol/EL section.

 

You could have an obstruction in your radiator. I had the same problem too. I flushed, bought new sensors, and a thermostat. Even checked the radiator and the flow seemed fine. Got a new one and it runs great
