No, because I cannot find one. Nor can I find reference to its location (if equipped) anywhere in my manual or on the web. I'd love to find a bleed valve! Do you know where it is?
Coolant not circulating--bubble?
2005 Escape Hybrid
I replaced the auxiliary water pump because it failed (no heat in EV mode). I filled the coolant reservoir to the full level, but it took nowhere near as much as drained out, which did not surprise me since I expected a bubble. I left the cap off, started the engine, turned on heater full blast and waited for the system to "burp." No burp, even after fans kick on (I shut off at that point) and no heat, either. I had to use the defrost to keep it running or the car would go into EV mode after about a minute. I took the new aux. pump off to check that it was not the culprit--water flows through it fine and I still have the same problem when I put the old pump back on there.
Is it possible that there is so much air in there that the main water pump cannot draw any coolant through the system? If so, what is the best solution for me to try?
Thanks

I'm using alldata.
No, I am not sure there is not something else going on, but I have not messed with anything except that little pump under/behind the radiator. I estimate I lost about four quarts of fluid during the swap and was able to add back about two quarts. Basically, filling the coolant reservoir to the full line and a little more that drained into the system via gravity.

This was part of my problem because it could never warm up properly with no coolant was being drawn through the system.skibender said:When you were waiting for the "Burp", did the engine get up to temp so the thermostat opened? I'm wondering if it wasn't allowed enough time to warm up.
Update: somewhat counter-intuitively, driving the car is what fixed it. Whether by sloshing the coolant/bubbles around or by increased engine load (high idle in garage had no effect), it slowly started to draw coolant through and I could fill with more coolant (after cooling down, of course). I started slowly with a lap of the cul-de-sac, then up and down the street, next thing I knew I was running errands.
