#11 of 56 My 2003 Honda is over heating, any help please
Oct 13, 2010 (12:30 pm)
I have a 2003 Honda Civic, I notice that it only takes a few seconds for my vehicle to warm up to normal. I can drive my vehicle for approximately 30 miles before I can see that it starts to over heat, once I exit the freeway it jumps all the way to the top. I have replaced the thermostat twice, just replaced spark plugs and had oil changed, not milky. No leaks found. My concern is what can make my vehicle reach normal temperature in just seconds. I can drive the vehicle sitting from over night and reach the normal temperature in under 5 minutes

I have a 05 civic LX, bought the car new. Until mid-Sept I had absolutely NO problems with the car. Took it in to a Honda Service Dept closer to home(not the original purchase dealer because of driving distance) and had the 110k service done plus compliance bushings, a strut replaced, etc. Paid over $1600 for all the work to be done. Picked my car up on Friday, seemed to be running like new. Monday, my daughter and I were running errands and the temp gauge went to hot. Pulled over immediately and shut the car off, called dealership that did the service, they sent out a tow truck and towed my car back at no charge to me. They said the thermostat got stuck, so they burped the system. Over the next few days the temp gauge continued to go up and down so I took the car back in. They replaced the thermostat. Car seemed to run fine again. A week later the battery indicator light on the instrument panel started coming on when I would start the car. My husband and I were taking our dearly departed dog to the pet crematorium when I lost all instrumentation. Husband says pull over, turn the car off and then turn it back on. So I pulled over, turned the car off-and tried to turn it back on with no luck. Car was dead. Called dealer who had done all the work on my car, they sent a tow truck again. This time they charged me a $150 tow bill. I firmly believed that this latest problem was a result of something the dealer had done(or failed to do) so I argued and got the tow bill reduced to $75. Service dept said Alternator went bad. It wasn't bad when the dealer did all the work on my car two weeks prior. I paid an independent mechanic $327 to replace the alternator. My mechanic also told me the brake fluid level was low-service dept did NOT tell me this or advise me there were issues with brake fluid level.
2 weeks ago, our weather turned cold so I had to start using the heater. Temp gauge showed car was at operating temp but it was taking a long time to get hot air out of the heater. Let off gas, heater would get cooler. Coolant levels were full, no leaks on driveway, etc. Took car to the original purchase dealer yesterday, asked them to find out why it was taking my car so long to blow hot air-they said the heater core was either failing or clogged. They wanted to charge me $1019 to replace the heater core-I declined. I also asked them to investigate why the brake fluid was low-they said the cam seal was leaking(cam seal should have been replaced when timing belt was changed but was not) and wanted to charge me $315 to replace that. Took car to independent mechanic, the coolant hoses were 2 different temps, car is getting heat, and he told me it is NOT the heater core. Drove home from his shop, car sat in the driveway for 30 minutes. Left to go pick up daughter from school which is 3.75 miles from my house. Waited 3-5 minutes for daughter, looked down and temp gauge was at hot! Shut car off. Opened hood, no steam, no apparent coolant leakage. Waited for 20 minutes, started car and drove home.
I have put in 3 phone calls to American Honda and am now waiting for a case manager to contact me.
If anyone knows what is causing this newest problem please advise!

Any updates? This sounds extremely close to what my current issue is with my 2003. I've googled this issue up one side and down the other. Seems to be a common problem, but no solution. On my path, I have had the water pump, thermostat, and radiator cap replaced. I have had hoses tightened and the system bled on a few occasions. My "current status" is that I might have a head leak, but I don't have any milk in my oil either, so I'm at a loss. I was thinking of taking it to a dealer, but after reading your post, I doubt there is a point. The only thing left is the heater core, that I can think of, and I don't think I'm ready for that yet. My whole problem started with no heat at idle to the point that I have had to pull over once due to over heating, but I have never had the car "die".
I'm starting to think there might be a design flaw in this series...

I beleive its in the water pump for $100 alex lol
if you think its the heater core look at the fire wall closest to passenger side 2 hoses larger then most but not as big as the hoses goin to radiator
remove clamps from both hoses and then remove hoses this is the entrance and exit from heater core you now have 2 options hook a hose up to the spot u removed the hoses from and turn on the water see if yuck comes out prob not
option 2 same as one but use compressed air if you have a compressor thats got an adjustment for psi that turns down most do you can put steady air into it once water stops coming out stop air if using full air pressure only tapp the release dont hold it if nothing comes out i tell you
or you could buy a flush but you have to drain and refill let run a couple times these will all clean heater core
but water pump this i tell you
no circulation = no heat to cab and a HOT motor

I have a 04 Civic LX 4-door. I have the same problem. My problem started after I replaced my timing belt and water pump at around 153K miles. I performed the work myself since I know enough about cars to work on the simple issues. Couple of months after I replaced the timing belt, tensioner, water pump etc... I noticed that the water temp gage gone up and down while I'm driving. In the morning when I turned on the heater, I got nothing but cold air coming out and will not get heat for until after 10 minutes of driving. Shortly after I turned on the heater, my temp gauge shot up to the red marker and down again..... and it just goes up for up to 30 seconds and goes back down a little and up again. This is worst in city driving or if you're stuck in a traffic jam. I replaced the thermostat the first time and it did not fix the problem and replace it again with another thermostat and problem persists. I also replaced the fan switches and temp sensor without any luck of getting it fixed. I also flushed the coolant system twice and problem still persists. When the car temp shot up, there was no smoke or fumes coming out from the exhaust or from the hood. Only thing that came out when this happened was coolant from the reserve coolant tank. I had the coolant system tested for signs of a damaged head gasket but it turned out fine. Inspect the engine head and no coolant leak coming out of the cylinder head. I've been driving more than 25K miles with this issue and change my oil every 5K miles and do not see any signs of coolant in the oil.
At this time, I'm at a total lost as to why this happened. My mechanic friend that worked on Honda cars for more than 20 years was not able to narrow down the exact problem. He performed all the basis tests and diagnostics without any luck. All he indicated to me is that I may have a water pump that was pumping in a reverse order.... meaning that the water pump is spinning int the right direction but the water pump propeller is spinning in the wrong direction because it may be reversed at the factory during assembly. I did not have time to remove the pump and verify this and I made a mistake by throwing my old pump away.
I hope one of you can find out what the problem is and share with us. I will do the same. Thank you so much!

I had the same issues with a 1992 civic. I replaced the timing belt and water pump. A couple of months later the car overheated due to low coolant. I seem to recall i had bubbles in the overflow reservoir. I got an exhaust gas tester for coolant-turned out negative. My theory-blown head gasket due to the low coolant condition. Head gasket eventually went about a year later-it was smoking out the neighborhood. I replaced all hoses, head gasket, hondabonded around the water jackets on the head and block, arp studs on the block and the head was milled. This head gasket was not going to be an issue again.
Fast forward another year-i have been constantly adding coolant to the reservoir every 2 weeks--the culprit---heater core.
The heater core was leaking the coolant out resulting in a low coolant condition. Check your carpet on the passenger side to see if it's damp. You might have to check under it. Also, your windshield will want to fog up more frequently. Try to look underneath the dash where the heater core is--you may see it dripping.
As for the surges in temp-or lack of heat. It may be air pockets in the system-either from lack of purging or exhaust gases from the head gasket making their way into the coolant.
Check your reservoir when the car warms up-the increased pressure from the exhaust gases cause the cooling system to over-pressurize and blow coolant out into the reservoir.
Also, I started vacuum-filling my cooling system to eliminate air pockets.
Hope some of this helps. It's been a crazy 3 years since all of this trouble began-and i just had the heater core repaired for $30 last week.--of course it took me 2 days to do the work.

When my head gasket was leaking-it was only leaking into the water jacket. And it seemed to be a one-way path. Exhaust would flow into the cooling system but coolant would not flow into the cylinder. Also, my oil remained clean.
Check your overflow reservoir for rapid filling when the throttle is pressed-indicating the exhaust gases pressurizing the cooling system.
To check water pump flow-you may be able to squeeze the radiator hoses to detect if the water pump is working.

Did you ever get an answer to your question about your 2003 Civic? My car has identical symptoms. What do I do?
