Now do BOTH fans come on? Where did you run the hose? Through the radiator? Does it bubble up in the overflow when the radiator cap is on? When the Temp gauge says hot see it both fans are on and blow HIGH. Look for air bubbles in the overflow. Check the springs on the radiator cap. They shouldnt be touching. Did you put the right thermostat in? The right way?
The water pump circulates the coolant. Under pressure the air should move toward the low point in the system which is the overflow tank. But if the cap isnt working the system cant pressurize and it may look like it overheating.
And how did you mix it? Was it pre-mixed or did you have to add water? 50/50?
Both fans do run on high once it gets hot.
I have flushed water through the radiator, heater core, and every hose.
Right now It is just water, no coolant.
I am loosing water. I do not see any on the ground and none comming out the exhaust. I replaced the radiator cap just to rule that out. The new 1 seemed to be blowing water out from around the cap. I put the old cap back on and it does not blow water out. That may be the only reason I was loosing water, not sure yet. The springs arre not touching on either cap.
I do get bubbles in the overflow.
