it is possible that when the water pressure rises in your radiator, and the radiator shoots the water into the reserve tank, that hose is not properly put on(happens alot when changing radiator) and the coolant leaks rapidly through there. another thing i suggest is observe your fan behavior. fans usually are only supposed to turn on for a couple of seconds, around 10 or 15. park your car, and let the car reach normal operating temperature. when the car starts to over heat, check to see if your fans turn off at all. if they do, then it is most likely the tw swith,or the water temperature switch. if you notice the fans stay running, then i suggest obesrving your hoses and replaing any that spill coolant because even a pressure test on your cooling system can miss a small pucture in a hose, which after a while will cause your coolant to leak, and your car to overheat. hope this helps. if still nothing, drop a comment and ill help you out somemore, but for now, this is the practical thing to do. hope this helps, goodluck.

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.

1993 Honda Civic rapid heating


Sounds like your electric cooling fan(behind the radiator) is not functioning. The thermostat might not be working,making the fan
not come on at all. I once put a toggle switch in my dash,when I had
an old CRX, just to turn on the fan, or it would overheat.

1996 honda


you know the fans are ok most honda have a two terminal switch at the right corner bottom of tthe radiator if you put a jumper across this terminal the fans should kick in, this indicates that the coolant temp sensor is bad replace it, secondly some honda have a temp sensor located right on the thermostat housing and you can disconnect the wire and just ground the wire and the fan should come on so replace the temp switch last thing to check for is coolant leak around the readiator seem i mean the edges the radiator being fiber glass may have hair crack through which antifreeZe keeps leaking out the only suggestion for honda is to replace the radiator.
