EXACTLY ! All this witchcraft for such a simple procedure. I do coolant changes here on Vanagons almost every week. No raising of one end or the other no Bong, or other complicated device. I have said this before and here I go again, one more time. Open the bleeder valve on the rad and thermostat housing, then with the engine running at idle fill the coolant expansion tank as full as possible. Now raise the RPM to around 2000~3000 and keep it there by blocking the throttle body or get a helper to hold it there. Now fill the expansion tank until fluid is coming out of the rad bleeder, close the bleeder, fill the tank, put cap on the tank, lower the RPM back to idle, connect the overflow tank which you filled to the MAX. mark and then let idle until the rad fan goes on and off three or four times. Close the bleeder on the thermostat. Let cool overnight and refill the overflow tank to the MAX. mark. The 2.1s are self bleeding and will always purge any air in the system after 2 or three heat ~ cool cycles. The 1.9s are a bit more finicky but the above procedure works just as well for them. Now this will be in the archives one more time, is there any space left ?
