Hello! I have been browsing the forums to see if others have run into the same issue as me without luck. Turning to the wise internet for some help. Here is what I have going on:
87 ranger with 2.9L auto. I just did a tuneup after i purchased it - plugs, wires, oil change/filter, coolant flush. After i did the coolant flush, its been overheating. i pulled the rad and flushed it both ways till water was clear, so i am confident there isn't a blockage there. I also flushed the block through the t-stat hole until water was clear coming out the lower radiator hose. I also installed a 180* t-stat. It didn't have heat before i did the flush and re-fill - still no heat. I flushed the heater core from the two metal pipes on the firewall till clear, so I don't believe there is a block there either. The hoses from the motor to heater core were also flushed - all clear.
As I am driving, the temp goes up to about the R and M and holds there for a bit. Then after another 10-15 mins the temp steadily climbs all the way to N or slightly above. As i shut it off there is lots of bubbling and gurgling, the over flow tank fills up. Once its cooled (motor off) the water is sucked back into the radiator from the overflow tank.
I am thinking it could be the water pump (and hoping so reading all the head gasket and cracked head threads). There is no smoke from the exhaust at any time when this occurs. Oil looks fine and there is no "snot" under the oil cap. I did notice one of the heater core hoses was very hot while the other was not hot at all, leading me to think there is little coolant flow through the motor. When feeling the upper and lower rad hoses it seems like there is some flow, but its difficult to say.
So what say you? Any ideas? Appreciate the help!
