I recently bought a 2000 Lincoln ls. I knew there were issues when buying. The coolant bleeder valve being 1 of the issues. I found where the bleeder valve was supposed to be, but instead i found a hose and/or a hose end with a bolt and hose clamp. So my question is, does the bleeder valve connect directly to to coolant reservoir or degas bottle? If it does, is it supposed to be putting in or taking out coolant, or is the nipple on the coolant tank a plug?
