With a littel over 6k miles and almost 2 years old (May), I decided it was time to change the coolant before the brutal Arizona summer begins. I have done this many times on my Accords, so I am pretty familar with the process on Hondas. I whipped out my trusty Helm manual and read the procedure before I began. Of course I was using Honda brand coolant just to be sure there would be no warranty issues. To my surprise I noticed that there was no "bleeder" screw on the thermostat housing as is the case with the Accords. Reading further I came across a part that mentions that after draining the radiator, it is necessary to drain the engine block! I know many of you old timers may recall how older cars used to be equipped with freeze plugs that were impossible to access so you could drain the engine. But what was interesting here is that Honda was suggesting this. To Honda's credit, they at least installed a "bleeder" screw which made the job substantially easier. In fact, I noticed after crawling under the vehicle with my work light, it was the same style bleeder screw used on the Accords thermostat housing! The most difficult part is getting to it. It is to the right of the exhaust pipes and way at the back of the block. The only way to get there is to jack up the van slightly and turning the wheels to the right make getting to it easier. After loosening it you need to attach a tube or hose to help direct the fluid into the drain container. No matter how you try, be prepared to get wet. Its impossible to rotate the bleeder screw with the hose on, so by the time you rotate the bleeder screw out sufficently, coolant is flowing pretty well before you can get the hose over it. Anyway, after its drained and you retighten it, the rest is straight forward, close the petcock on the radiator and refill with 1 gallon of coolant and the rest water. Don't forget to change the resovoir bottle too. This is the easiest part as the bottle pulls straight up and out. Fill the bottle half to the max line with water and up to the max line with coolant. Install the radiator cap loosly (only turn on it half way). Run the engine with heater set to high until the cooling fan comes on twice, wait for the engine to cool down and open the cap to make sure you have enough, if not top off with water and you're done.
