I have not converted to open cooling yet. I am planning on it though. The temp gauge gets up there in the red pretty quick. I know theres a little air in the lines but the top radiator hose is not moving fluid at all. is this the water pump? Also i think someone put stop leak in it cause the fluid in the reservoir looks like it has some grainy sawdust looking stuff in it.
this stuff was foamy feeling. What is it though?!
