Van warms up the same way it always has, no problems there. Engine is running great given it’s age and milage. Engine starts right up and runs smooth. Over the 12,000+ miles and year and a half I have owned it I have had to add antifreeze once and it was like maybe a cup or to and that was back in early 2011, since then the level has not changed one bit. The dip stick has not shown any gunk at all at either the tip or at the top which I have had happen on other cars I have own. I cleaned the cap and will monitor it.
