Question about 2004 Honda Civic

Open Question

Heat blows cold and hot, temperature gague fluctuates, rough idle on startup.

Ive replaced the timing belt and water pump at 90k, Car now has 117k on it. Ive also just replaced the thermostat and radiator cap. No oil in antifreeze and no water in oil. No white or black smoke. temperature gague will fluctuate and go almost to h then it will come back down. Did have coolant loss but since the hose clamp was replaced this doesnt seem to be an issue. Also fans work well. HELP!!!

SOURCE: 04 civic heater blows cold air at idle

you should have hot water on all rad. hoses when the motor is running at a norm. temp. the water is not going through the heater core like it should. you have cutoff valve bad low water are a stopped heater.try a hoter thermostat if none of the above are true.

SOURCE: oil leak through the distributor

why do you need to remove the filler cap when the car is running???
There is a seal around the distributor. Mark where the distributor is and remove it. Then replace the seal. Put it back together in the same location as before you removed it. It is also possible that your valve cover gasket is leaking and dripping on the distributor.
Cooling problem: Try washing the outside of the radiator where the cooling fins are. Spray it down with a really good degreaser and rinse it off. WARNING: Do NOT use high pressure because you will need a new rad after.

with your description it sounds like your fans are not coming on, also sounds like the problem was never solved, sounds like you threw a lot of money at your problem also... check to see if the fans are coming on at the right times, seems like a n air movement over the radiator since you say it only gets hot in stop and go traffic... well when your driving at a constant highway speed guess what you have air movement through the radiator... check also a clogged ac condensor with bugs, pressure wash it out so the air can pass through it easily... please rate my help thanks

I had a similar problem with 2003 nissan sentra, no heat , and car would stall on road on and off. Became a problem more frequently stalling. Took to nissan and they said it was head gasket. Fixed it and never had problem again. But i had it fixed at a local dealership since nissan was charging 1000.00 compared to 550.00. I replaced water pump and thermostat first b4 this and no cigar.

Hi i bought 2002 nissan sentra ..previous owner replaced head gasket ,water pump.thermostat ...car was running good for a week then sudeny no hot air inside(blows but cold) and 10 minutes later...


Thermostat is the wrong temperature range for the vehicle or it is installed backwards. It is opening too soon and not allowing the vehicle engine to come up to operating temperature soon enough. Have system checked, replace thermostat with correct temperature for vehicle

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


1. Error Code 24. Intake Air Temperature Sensor.
Solution:
Check the following:
- IAT Connector and wiring.
- Intake Air Temperature Sensor.
- Engine Coolant Temperature Sensor.
- ECM.
2. Rough Idling when the engine is hot.
The following are the reasons due to which the engine can perform bad when it is hot.
- Fuel pump control circuit.
- Fuel pump pressure.
- Fuel injectors.
- Non Return Valve clogged, located on the lower side of car chassis above the fuel tank.
- Engine compression, valve clearance, spark plugs.

I have 2001 alero. Yesterday the coolant light came on and the engine just died. Any ideas maybe fuel pump or timing belt or could it be the water pump


IF LOW COOLANT LIGHT CAME ON ENGINE SHUT OFF BECAUSE IT GOT TOO HOT AND OVER HEATED.WHEN YOU HAVE LOW COOLANT.YOU COULD HAVE LEAKING RADIATOR.YOU COULD HAVE LEAKING RADIATOR HOSES AND WATER PUMP. ADD MORE COOLANT IN CAR RADIATOR UNTIL YOU AT FULL COLD MARK ON THE OVER FLOW COOLANT TANK START THE CAR LET IDLE UNTIL ENGINE GET OPERATING TEMPERATURE.RAISE YOUR HOOD LOOK FOR LEAKS THE RADIATOR PRESSURE WILL PUSH COOLANT OUT WHERE LEAKS COULD BE.LOOK AROUND RADIATOR AND COOLANT HOSES.LOOK AT WATER PUMP.IF YOU SEE COOLANT LEAKING AT WATER PUMP REPLACE IT.

MY HOT AND COLD METER KEEPS RISING AND FALLING


If the fans are electric, then replace the fan control module.
If the fan is belt driven, replace the fan clutch.

There is a chance that the thermostat is failing, but if the temperature fluctyation occurs during driving, as opposed to stopped and idling, then it's probably the fans.

AudiA3 Bad Idle and rough at certain revs


buy a bottle or two of gas line anti freeze, it absorbs any water that may be in your fuel. add one bottle now and one the next time you fill up. if it is water as i suspect you will notice results almost immediately.

When to change timing belt on 2004 honda civic


Honda reccomends timing belt change at 100k. Most Honda dealers like you to change the belt at 90,000 miles (90k). some auto repair places will want to change the belt at 60k but that is not necessary (Note: if in a severe cold or hot climate like florida or canada you would change the belt before 90k or if the belt is over 7 years old.. Good luck:
