  • ladycaba Dec 13, 2009

    iv been driving it to work for the last three years in this condition (adding water and coolant every morning). would i still be able to drive it like that if it is a head gasket?

    Not to overly consider the less dramatic, but I repeat, have you changed the radiator cap?

    Did you change the radiator cap? Sounds like it's not holding pressure.

Sorry to hear all this has been going on and the obvious hasn't been detected by a shop. All those parts probably would not of had to be replaced. This is a classic systom of a blown head gasket. Not every head gasket blown will have coolant in the oil. Compression leak from a cylinder will enter water passage in head and blow out the coolant because compression is greater pressure than coolant system pressure.

Sounds like the thermostat is not working properly on your car. I would suggest changing it out, and

getting a radiator flush. if that thermostat freezes shut and does not open when the engine gets hot.

you could have bigger problems, like a blown headgasket, ruin your water pump or rupture radiator

hoses. good luck!

if its an overheating problem the cooling fans may not be coming on.this needs to be checked.it could also be a bad temperature sensor for the computer and its getting the wrong temp reading,thus not turning on the fans.there is also a cooling fan relay(not a problem that happens often).one other thing the impellers on the water pump may be worn out or not turning with the pump shaft.

My honda civic radiator blowup what can be the fault


Hi!!
A radiator can blow up due to several reasons, the main and most frequent are:
  • A faulty Thermostat.
  • Low or leaking Coolant,
  • A defective or unplugged Coolant Temp. Sensor,
  • Defective Water Pump,
  • Faulty Radiator Fan Relay or blown Fuse.
  • Faulty Radiator Fan Motor or wiring,
  • Clogged Cooling System passage or Radiator.
  • Worn out (too soft) Radiator Hoses.
  • Wrong size Radiator Cap.
  • Dirty A/C Condenser Coil (the coil in front of the radiator)
Good Luck!!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

2002 civic ex overheating


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

Engine over heating.


deep copper color is only rust. you can remove that by back flowing the empty system. There exist some cleaning fluids to let it run for a while as well. Go to autoshop.
Check fan by connecting direct to power if ok, suspect temperature sensing switch on the block.
The old thermostats can cause boiling over, they need replacement once in a while. You can check this with a oven thermometer old style in a opan of water on your stove reading the watched opening temperature. Replace with right value. They come in sorts some times.
