The petcock is usually always located in the corner of the radiator. Once located, get a pan of some sort, such as a disposable aluminum pan from the store, and place it directly under the petcock. When in place, remove the petcock and let the coolant drain into the pan.

How to Change the Coolant in a Honda Accord

1. Turn the heater control inside the Accord to maximum heat.
2. Open the hood and inspect the engine and radiator.
3. Remove the radiator cap carefully by hand.
4. Move under the car.
5. Locate the drain bolt on the engine block.
6. Pull up on the reserve tank, near the radiator, to remove it.

To put the coolant into your Honda, unscrew the top of the overflow reservoir, and slowly pour in the mixture until it has reached the full mark. Tightly replace the cap on the reservoir and you are all finished! Coolant should be changed every couple of years, following the recommendations of the manufacturer.

No, not unless you put so much in that it clogs the cooling system. It stops leaks like small pinholes in the radiator. It won’t repair hoses, head gaskets, or a bad water pump.

4 Common Signs of a Radiator Leak

• Radiator Discoloration. Pop the hood and look for spotting on the radiator or around the engine.
• Low Coolant Levels. Part of your routine auto maintenance should include checking the coolant fluid reservoir to make sure it is full.
• White Exhaust Smoke.
• Leaking Coolant Fluid.

Driving with a radiator leak is a dangerous operation, as it will very likely cause your engine to overheat. If you are driving down the road and notice your engine is overheating, pull over immediately and let the vehicle cool down.

You should be able to take a vehicle at least 5, maybe 10, miles by following this advice. I should say that I live in an area that never freezes, so… A much cheaper option then towing, but which will ensure that nothing gets damaged, is for you just to fix the leak temporarily on the spot with some putty.
