where is the coolant bleed valve?
I am trying to change coolant but I can't locate the bleed valve in the back of the block. If someone can help me out with a pic or a description, that would be awsome.
thanks

as far as I know there is not one.... fill the rad up with Honda Pre-mix and leave the cap. off (mind you, you only fill it when the motor is COLD)...
leave the cap off and start the car..... squeeze the rad hose a few times... wait a couple minutes till you start to see the fluid level rise and the fluid is about to come out.. then cap the rad...
Watch your temp gauge.. if it goes above normal, that means you have an air pocket... will need to let the car cool and then open the rad cap again... Although the car is coolded down.. I HIGHLY recommend you use a large towel to put over top of the rad cap while removing it... just in case, so you do not wear the fluid that is under pressure...
Fill and repeat till the air pocket is removed... just watch your temp gauge.

I spoke to several dealerships and all of them told me that there is no point of draining the block and that draing the radiator is sufficient. However, I was told that there are two bolts that drain the block, one of them is in the back of the block by the header bracket (19mm?) and the other is in the front of the block. When I looked under the car, I could not locate those particular bolts as they are not marked and look identical to others. In the end I just drained the radiator and filled it with Type II coolant from an Acura dealership. (do-it-yourself = $12 & 30 minutes; dealership = $65 & probably longer).

the block drain is on the rear of the block and has a nipple on it. it's small, maybe a 8mm bolt. attach and length of tubing on it and loosen it, no need to remove it.

There is no "bleeder" screw on these cars .You should drain the block for a proper coolant changeout .Generally speaking what I do is completely drain and then completely refill the cooling system ,then I overfill the overflow bottle .Then I place my hand over the radiator filler and squeeze the upper radiator hose vigorously so that the remaining airpockets escape to the overflow bottle .After this I drive the car till it is warmed up and let it sit .As the car cools the excess coolant in the overflow will fill up the remaining air pockets in the cooling system .
