Coolant level and oil cooler question
when I bought my truck the coolant level was at the full level and since had dropped to about half way between the marks and leveled off. I could see coolant residue on the tank, which I always cleaned off, so I can see if it is puking still. Today I made a 4 hr 70 mph round trip with about 2500 lb load in the bed for half of the trip. I checked the tank and it had puked some. I don't have gauges yet and haven't done a coolant flush yet.
Now my question is if the coolant level is at the min. mark ( which I believe is the proper level if I read right) will the coolant still puke out if the oil cooler is plugged?
