degass bottle flow

[TurboFlush]

In short.. Is the small line suposed to flow all the time or before the thermostat opens?

 

I ask because i had drained the radiator for some work. Many days long.

I forgot to refill and ran the engine while i put tools away. Fan kicked on and i instantly remembered and shut it down.

Filled the system.

Doesnt over heat. No coolant in oil. Drives fine.

I think i wipped out the pump fin's. But want to make sure i am not just paranoid.

 

Come to find now that the chains aparently stretch and water pumps fail near the 200k mark. 160k on mine.

 

If i pinch off the top radhose i dont get anything from the surge tank vent. No

 

No heat from heatercore. Could be air bubble.

 

Next chance i got i am thinking to pull the top rad hose and see if i get any movement.

don't know MY or engine, but assuming early Gen 1 3.5L ... 2009 coolant flow diagram

I got that. I know what direction it is suposed to flow into there. But when? I am getting none.

 

Can someone confirm.. It flows when cold and/or when warm? Higher engine rpms?

 

I couldnt find any conversation on this on google or any videos showing it in a refill procedure.

It will flow when the thermostat opens.. I had to refill the degas bottle a couple times when I flushed the coolant in our 2014 Edge 3.5 and my 2011 Mustang 3.7.

 

Unless you have a big air pocket

Good to know. Thank you.

 

Pulled the trigger on the stuff to do the chain and pump. Hopefully the chain will be a good quality. Didnt buy ford. Not replacing phasers or sprockets. 160k they should be fine. But will inspect.
