We are having the same problem described with the overflow tank blowing open and spraying coolant all over, We tried replacing the temp sending unit and sensor but still having the same problem. We are going to try replacing the waterpump next, Has anyone found a solution to this problem? delwood96yahoo.com

Replace the valve, it's a known problem, with the symptoms you've described.

my truck has a plastic heater valve ,it was leaking a little around the shaft with tthe heater on.it was sucking air and making air pockets and when the air would hit the sencer for the gauge it would go down and when it passed and the nwater came back the gauge would go up.i replaced the heater valve and since i did that it has been ok.

#31 of 33 98 Ranger 3.0 Coolant Problem! by taco1967

Nov 21, 2011 (7:36 pm)

I have a 1998 3.0l Ranger and cannot figure the coolant problem out. The heating system worked fine until I flushed it last year. SInce then, I have replaced the thermostat twice, the second time with a quality replacement part, bled the air out of the system, replaced the rad cap, and that hasn't worked.
The symptoms are: coolant goes to reservoir but will not return. When I tried to get the air out, I followed protocol, but upon opening the throttle to 2000 rpm and completing the fill, the rad fluid just gushes out the open rad neck. I get heat upon initially running the engine, but once the fluid is kicked into the reservoir, heat ceases. The temperature gauge never goes above 1/2 way, and it is not over heating. I do smell coolant in the cab, but not sure if it's just from the top popping off the reservoir. The exhaust has been noticeably thicker and whiter, and no coolant leaks can be detected other than the reservoir overflow.
Both upper and lower hoses are warm when running, and the water pump does make a ticking noise when running. Please tell me it is either a water pump or even a heater core, not a head gasket. I'm not sure........
 
THANKS!

Bad radiator cap? It get hot and pushes coolant to the overflow reservoir, but the little valve in the cap is not working right. It's not opening up when it cools down and pulling the coolant back into the radiator.
 
Or, the rubber hose from the cap to the reservoir is bad. Somewhat same problem, it pushes coolant to the reservoir when hot, but when cooled down the hose allows air to be pulled in rather than coolant from the resevoir.
 
Or, it there is a leak in any of the hoses - radiator or heater - the same thing happens. When the coolant cools down, air is pulled into the system rather than coolant being pulled back from the reservior.
 
In general, the cooling system has to be air tight everywhere or there will be problems.
