Honda Civic Overheating And Smoke

Posted in Internal Engine Parts

I have a 2000 honda civic, this morning i noticed a very small plume of smoke or steam, not sure which, then saw that my temp gage was almost in the red. I turned on my heater and the temp went down, but still slightly elevated. I pulled into work and popped the hood, and there was a very very small amount of the smoke or steam, not sure which, but it has no odor, coming from near the coolant housing compartment. It was too hot to check the water level, so ill do that later, but based on this info, what does it sound like the problem is?
and… should i be worried about making the 20 mile trip back home ??

      Could be a head gasket or just needs a flush

      Your car is overheating… could be several things. You need to have it checked out ASAP… the majority of overheat issues are minor repairs… but the remainder are usually expensive.

      Minor / Major coolant leak
      Defective thermostat
      Restricted radiator
      Defective water pump
      Blown head gasket
      Etc. Etc.

      – Good Luck!

      It looks like you are going to need a new radiator. sorry and good luck

      Water pump?

    5. Sir Shaw says:

      Was it the radiator cap – if so could be the water pump gone OR could be a hose leaking by the radiator…just take it to a shop…….WORST case could be your head gasket gone which causes compression to get in the water way which could lead to an overheat.

      I would never recommend DRIVING any of my own vehicles if they were overheating and would advise you to get it to a competent mechanic promptly. Of course, you should first have: (i) check & open radiator cap and refill the radiator after engine has cooled down with water or 50/50 coolant and then I would carry along either gallon bottle of water or 50/50 coolant and rag before ever attempting to drive a malfunctioning to a service station and definitely watching your gauges pullling over to shoulder and waiting 30 minutes if it were to overheat again

      Personally I belive it is either your thermostat or radiator cap unless you have high mileage then maybe a water pump (makes lot of noise) or radiator .

      NEVER Drive OVERHEATED VEHICLE bec bad would only become worse, and if necessary call for tow truck bec DAMAGE from lack of OIL <= Hopefully you checked oil level as well CAN NOT BE REVERSED and COULD GET WORSE FROM LACK OF LUBRICANTS! Hope The Above Info Helps & Best of Luck!

      For the less-serious possibility, the rubber seal in your radiator cap may have worn out thereby allowing steam of hot coolant to escape out from your radiator cap. As more steam escape, the less liquid coolant you’ll have in your radiator to help cool down your engine from overheating.

      Radiator caps are very inexpensive and replacing it is as easy as twisting the old one off (only while cool), and twist on the new one.

      If this doesn’t resolve your problem, you may have a leak in your radiator or radiator hoses. It could also be a bad fan or fan relay fuse, a bad radiator fan, or a bad engine coolant temperature (ect) sensor. If any of these parts are faulty it will prevent your fan from spinning when your engine reaches high temperatures. At that point, only the wind as you drive or the wind itself can somewhat help cool the engine coolant in your radiator if your radiator fan is not spinning. Also, turning on your heater on full blast will draw the heat out from the warm liquid coolant to help cool your engine a little.

      Don’t let your engine overheat into the red temperature zone for too long, it can melt the surface of your pistons and ruin your engine. Allow time for your car engine to cool down. Buy extra radiator coolant to help you get by where you need to go for help/repair.

      Good luck!
