I Just bought the car a couple months ago it is my first car. Only had 114,000 miles on it when I purchased it. It now has 127,000. It over heats almost every time I drive it. I just replaced the radiator and the radiator cap. It obviously has not fixed the problem. I do not know how to tell if it is my head gasket that is blown, but it is so stressful. I have been reading and a lot of people have been having the same issues with the same kind of car. I even took it to a mechanic and they told me to replace the radiator but that did not help. Anything will help :/

Has thermostat been replaced, and are cooling fans working? A compression test will tell you if head gasket is blown. Also, there will be combustion gases inside of radiator.

Yeah, I replaced the thermostat before I replaced the radiator. And yes the fans are working. I hear them come on when my car is idling. How do I do a compression test?

And when I try to turn the heater on it blows cold air. Sometimes it will blow warm but then it just goes cold.

Did you use the bleeder screw on the cooling system to bleed the air out if the cooling system after replacing the radiator etc?Are both heater hoses getting too hot to hold when the engine is warmed up and there is no heat inside?

I've done a lot of research and unfortunately a lot of these cars have had blown head gaskets. I check the oil regularly and it seems to be fine. But that's they only way I know how to tell if it's my head gasket.

Auto zone rents a chemical block tester that the fluid will change from blue to yellow if there is exhaust gases entering the coolant system The rental is free with deposit you just have to buy the fluid.A compression test can be good and still have a blown head gasket.

They say blown or cracked head gasket. They did a block test and found fumes in the engine. Explains why I was constantly putting water and coolant into the system. That'll be the last time I purchase a Honda.

So I ended up but a head gasket sealant called BlueDevil just until I can sell my car and get a new one. Bad mistake. I put it in there and the car doesn't over hear at all now BUT it's leaking an extreme amount of coolant while the car is running. After I noticed it was leaking I let it sit overnight with cardboard underneath it and I checked it in the morning and there was like 2 little drops. So I open up the radiator cap and it was completely full. No room for me to add water or coolant. But the night before it was losing quit a bit. I'm not sure what could have caused that?

That's a hard one to say without being able to see where it was leaking.I would never recommend putting that stuff in.
