I jave a 2001 Honda civic and the maintence required light is staying on. Tried to reset it but cant. WILL IT STILL PASS SMOG? Im told yes because it isn't a check light it says maintence required. I think it's the same as a check light but was told otherwise.

The manual for my CRV is very easy to understand and reset the light. Do you have the manual?

Yes I have a manual. It passed smog also. I guess the maintenace required light isn't the same as the check light which would stay on and it's a picture of a small engine

Your manual should show you how to turn off the maintenance light. That is not a check engine light, it just tells you that you need to check into an oil change or other periodic maintenance.

I have a 2001 Honda civic that has me pretty well baffled. First let me say the temperature of my car is my pet piv. My car was overheating out of the blue on certain occasions and it would rise very fast so I hd it looked at and so far have put a new fan censor in, a new radiator and thermostate and had my resivor crack fixed with some top of the line glue for that. It never really leaked that we could see. Then it did it again going down the freeway and traffic was all of sudden stop and go on freeway and it started to over heat I would turn on my heater to help it cool down which blew out hot air and then all of a sudden it turned cold as my temperature would rise and drop then rise and drop eventually just rise. It would be now on occasion a cup mabey two low but see no leak. Could it be my resivor should I get that new too? Any suggestions. When it is cold in the morning and I check my water sometimes its pressurized and sometimes not.

Has a hydrocarbon test been run on the radiator? You can have a bad head gasket without coolant going the other way into the engine though its not usual.

It tests for combustion gasses in the radiator... and they only way they can get into the coolant is a cracked block or head.. or the more likely bad head gasket.

Read your Owner's Manual on how to properly fill the cooling system. It's likely the temperature slide should be set on high and you may need to turn the ignition switch to Position II, in order to open the heater control valve. All of this is to prevent air pockets from developing in the system. Also, make sure the bleeder bolt is open, while you are filling the radiator. Failure to do this properly can blow the head gasket, warp the head, and damage the valves.
