1999 Ranger 3.0 Auto Trans. (195k Miles)
Over the summer (june 2010) I my truck overheated and it was due to low coolant. I found the problem (see first picture). The gasket behind the front main seal must of went bad, and its a very very slow leak. So ever since I just top my coolant off ever month. From the looks of it, the H20 pump, main pulley setup and everything must come off to fix that gasket. And i was told once those crank sensors are removed you need to buy a new one. Any input?
My second issue deals with my coolant gauge in the cluster. After I realized my coolant leak I did a full flush and ever since the gauge was acting kinda odd. It currently doesn't move from the "cold" position, even when the truck is warmed up. I am getting good heat and My Scanner reads ~ 185 degree coolant temp.
The other day when I turned my truck off (~ 5 Minutes) to fill up, I came back in and turned it on and the gauge moved up to normal operating temp, but as i drove away the gauge fell back to the cold position.
