Cooling SystemEnsure that the engine is completely cool prior to starting this service. 1. Remove the recovery tank or radiator cap. 2. Raise and support the vehicle. 3. Place a drain pan of sufficient capacity under the radiator and open the petcock (drain) on the radiator. è Plastic petcocks easily bind. Before opening a plastic radiator petcock, spray it with some penetrating lubricant. 4. Drain the cooling system completely. 5. Close the petcock. 6. Remove the drain pan. 7. Lower the vehicle. 8. Determine the capacity of the cooling system, then property refill the system with a 50/50 mixture of fresh coolant and distilled water. 9. Leave the recovery tank or radiator cap off to aid in bleeding the system. 10. Start the engine and allow it to idle until the thermostat opens (the upper radiator hose will become hot). The coolant level should go down, this is normal as the system bleeds the air pockets out of the system. 11. Refill the system with coolant to the proper level. 12. Turn the engine OFF and check for leaks.
go to the auto store and buy some prestone flush. instructions are on the back. basically you drain your radiator, pour in the flush, refill the system with water, run the engine with the heater on high for about 15 minutes, then drain the system again, refill it with 50/50 coolant.

you probably need to flush the coolant system. GM claims that the coolant is good for a ridiculous number of miles, but it is not so. The coolant breaks down and forms large clumps which will clog up the heater core. You may need to flush several times to get it all out.
Years 1997-2000 is green coolant. I don't know the newer vehicles.
there isnt one after 1996
If your vehicle keeps overheating, you should flush the cooling system, replace the coolant, and replace the thermostat. In fact, you should have done that before this.
The thread on cap on your engine coolant reservoir is the " radiator " cap
probably the heater core is clogged
it is behind the thermostat in the water jacket
Check your owner's manual. It recommends Toyota brand longlife (red) coolant. Toyota coolant is 'similar' to GM's Dexcool (orange) but the chemical makeup is slightly different. Do NOT use standard (green) Ethylene Glycol coolant unless you completely drain and flush (at least twice) your cooling system. Cheers
how do i bleed my accord v6 2000 coolant system, its has air and the rev's gone up & down......
flush the system and change thermostat,this should fix problem. I flushed mine and i changed coolant and thermostat,it is now fine.
