Why is my 2004 honda civic overheating

It just means the leak is small enough not to cause visible smoke. Probably time for these. If you get this done your car will probably be good to go for another 5 years with out much trouble. I would really hate that i would need to get the head gaseket replaced. I bought my '04 Civic EX new.

After the repair, the car is at k with no further problems. And it sure sounds to me too like you may have a blown head gasket. One of the characteristics of a blown head gasket is the fluid not returning to the engine when the engine cools. Normally as the engine cools and the coolant contracts, it draws the coolant up from the reservoir like milk up a drinking straw. But of there exists a path between the water jacket and a cylinder, it will draw air into the water jacket through that headgasket breech instead.

I have an '07 Honda Civic with roughly k on it. About 3 weeks ago I was traveling from Alabama to Tennessee. While on the freeway my car started overheating the temp gauge started creeping up, t I've replaced the sensor 2 times, and have a spare ECU. Nothing is fixing the problem. So, I've bypassed the Blue wir Review another car.

Could it be anything else? Do you. It could be the fans are not turning out here is a guide to help test the fan motors and a general guide on over heating. Was this answer. I love this site. Replaced pump timeing belt. Put back togeather, cranked first turn over. Run hot, replaced thermostat. Still ran hot lower radiator was cold top hot.

Tried to bleed system bottom hose got warm, not hot and could get not heat inside car. Heater on. Fan off. Car run great, runs up to normal on heat, race motor are drive it it gets really hot. Any help. Thanks Was this answer. So how did you bleed the cooling system? Sounds like you have air in the system.

I tried several ways, I took the cap the cap off and fast idled idle the motor that didn't work. Then pulled the fan switch out as a bleeder and tried that. Any thing you tell me will help. Saturn tech9, think I solved the overheating problem.

I had to let it get cold and then bleed it just did that and got heat and so far no over heat. I had done this on 05 Nissan and just had to open cap and let air out, more air with water pump I guess. Thanks for answer back. Glad to hear it usually the hondas have a bleeder screw up top you start the engine and crack open the bleeder and wait till you get a steady flow of coolant out of it. My car has been overheating. I have had the radiator, thermostat and even a head gasket replaced and for some reason it is still overheating.

I cannot figure out why the coolant has been changed and flushed. The vehicle overheats randomly and it smells like burning rubber. Any suggestions or help would be appreciated. Thank you Was this answer. When I bought the car it worked great, everything I could have wanted. However, that soon changed when it began overheating, and to be specific it is a honda civic ex, automatic. I took it back to them after having to pay towing expenses.

They said they didn't know it had issues bull they said it was due to a radiator, so they installed a new one. When I got it back it drove fine then it began exhibiting the same symptoms soon after. I decided since I loved the car I wouldn't even bother with the people I bought it from, big mistake and I should have just returned it I didn't because I was sick of looking for a car and school was about to start.

This began the routine of having to fill it with antifreeze everyday before and after class, if I didn't it would most certainly overheat and then I'd have to blow hot air all day. So I took it to another mechanic who figured it must be something wrong with the cooling system and said the fan was acting slow, so he replaced the fan-switch and thermostat and said that it wasn't the water pump.

I was hoping this would do it, but it did not. He then tested the head-gasket twice and it came back negative. Then they tested the catalytic converter, came back negative.

This mechanic, then proceeds to tell me the people who sold it to me may have put a sealant in which gummed up the engine and is clogging things so it can't function correctly, or put on the head-gasket wrong or any number of things to the engine. Although, wouldn't this still make the head-gasket test fail? He tells me I may need a new engine because to figure out if it truly is an engine problem that would cost as much as a new engine. I don't know what to do or where to go I am at a loss here.

Spending my money just to have mechanics tell me there is some mysterious "undiagnosable" problem with my car is the most frustrating thing ever. No one can fix this car it seems. If you are losing coolant you say you have to add coolant daily , then there are only two places it can go. Either on the ground or in the engine. Check your oil to see if it's a milky color. If it is, then the oil and coolant are mixing and you will need the engine rebuilt.

If not, then you probably won't need to replace the engine. Next, does the exhaust smell sweet? Is it extremely humid when exiting the exhaust tip? Is there any white smoke from the exhaust? If so, the coolant is leaking into the combustion chamber, and being burned off.

This indicates a problem with the head gasket. Is there any coolant on the ground? You should be able to pretty easily determine where it's leaking, if there is such a leak. Check the passenger floor to see if it's very wet. Is the air very humid when you have the defrost on hot to help with cooling?

If either of those is true, the heater core would be the area to look at repairing. Total agreement with dobey.
