Re: LIGHT IN DASH BOARD
DO NOT operate your CRV until you have drained the coolant from the engine and radiator, then flush the system thoroughly w/ water.. Why did you add liquid detergent to the radiator? This will cause foaming of the detergent, and will probably result in diminished cooling of the system. Please describe the dashboard light that's on . Is it some type of symbol? Do you notice anything unusual about how the car is running? Please let me know the answers to the above questions, and the outcome. countrycurt0

could be the heater radiator that is leaking.they are normaly behind the dash board where the fan blows over it to supply heat. If you can locate heater pipes in engine bay, blank them of and see if water build up stops. these radiators are rather tricky to get to!
Honda has a blue anti-freeze that comes in their radiators. It doesn't have additives that can damage the water pump. Look on the back of the anti-freeze and get one recommended for honda or go to a dealer.
If you have added water/antifreeze only once, there is still air in the cooling system and it will take several topping offs to completely fill it. If you have already filled it several times and it still looses fluid, then you may have blown a head gasket. Top off the radiator again and run the truck to get it up to operating temp. Open the radiator cap (slowly and carfully so it doesn't blow out at you) and see if there are any bubbles coming up in the radiator. This is a sure sign of a leaking head gasket. Also white smoke from the exhaust pipe is another telltale sign.
SOUNDS LIKE YOUR THERMOSTAT IS STICKING,REPLACE THERMOSTAT FIRST OVERHEATING WILL DAMAGE ENGINE.IF THAT DOSEN'T WORK HAVE WATER PUMP CHECKED.FANS WON'T TURN ON IF HEAT FROM ENGINE IS NOT FLOWING INTO RAD BECAUSE THEROMOSTAT STUCK CLOSED,OR WATER PUMP FAILING
Exactly what maintenance did you perform 3 weeks ago? There should be a drain at the bottom of the radiator and also on the engine block. The coolant should be drained at both points, refilled with water, drained again. I would do this several times to flush all the detergent out. The exact location of these drains can be found in a repair manual for your Honda. You can also get info @ eautorepair (there is a charge, but I think the site provides lots of valuable info) If you have the owners manual, it should contain some of this info. After the system is flushed out thoroughly, refill w/ 50% coolant, 50% water. good luck! countrycurt0
Good, you did not add much detergent to the radiator recovery bottle (plastic bottle). You say half a cap, would that be about one tablespoon? If yes, I think it would be ok to drive, but I still would recommend flushing out the system just to be sure it has no bad effects on the cooling. countrycurt0
