My winter beater is no longer safe or reliable, so I have to get the Stang on the road.

Fired her up - she started right away. Then a VERY load screech and smoke. Seems the serpentine belt was starting to smoke, it wasn't moving. I opened the rad cap. The coolant looks like very hard slush. I think the coolant froze? I had a 60/40 (Prestone antifreeze) mix in it. I think (?) the water pump isn't turning and is frozen. The frost plugs are intact. It is about 0*F outside.

I wonder if I take off the serpentine belt, and run the engine for 3 or 4 minutes,would I be able to "thaw" the engine and flush the coolant?
 
QC use an small electrical space heater and put it under the hood, tarp off the front area to keep the wind out. Sister lived in Montreal for a few years, had the same thing happen, that's what we did.
 
Well, she's alive.

Due to my previous shoulder problems, I didn't have the strength to get the belt off, so I went with plan B.

I had to use a hairdryer+electric heater+block heater while she warmed up in the sun (it finally warmed up to 20*F).

I checked the rad before starting it up. When I took the cap off, ice cold Prestone shot everywhere. A lot of pressure in there.

When I started her, she belched a little carbon, and the belt squealed for a few seconds. After a 5 minute idle, it stalled going into the street. When I started again, it stalled in reverse. I drove her about a mile to get gas (I had 1/4 tank left) . No more stalls, smooth as heck...


95cobraguy - I can't stand the cold either...
