Question:

Coolant System Bleeding Valve ?

Ok so I have a Honda Civic 97 lx and what happened was that when I did an oil change the next day the car started over heating, the car only had pure water and no coolant, the over heating part happened during noon when I was driving on the freeway the next day and not the night I made the oil change... After that I decided to put 50/50 coolant but the car still over heats, a friend told me that I probably needed to do a coolant system bleed, I try to do it but I couldn't find the bleeding valve or bleed screw... can anyone pls tell me where that valve or screw is located, I discovered a sort of valve that is covered by a black rubber cap , its next to the engine I don't know if that's what I'm looking for.....

Answer:

You can also get a good bit of the air out by removing one end of the upper radiator hose from the car and filling it with antifreeze. I recently had a 93 Civic in my shop that DID have a bleeder valve on it. If your car does the person above gave you the correct method of bleeding it.

The bleeder valve for the cooling system should be on your thermostat housing. Follow the upper radiator hose to the engine. Where it connects is the thermostat housing. There should be a bolt in the round part of it that does not hold it down. Make sure the engine is cool and NOT running. Remove the bolt and add coolant to the radiator until it comes out of the hole.
Your car does not have a coolant system bleeder valve built in. Most of the time you would bleed it using the coolant temp sensor as your bleeder. Remove it with the engine cold and start the car. As soon as a steady stream of liquid (without bubbles/air pockets) becomes visible, quickly thread the coolant temp sensor back in and snug it down. Shut the car and top off the coolant reservoir and your done. Good luck!
