The T.I.B.
is rarely serious
When working on your car in freezing winter conditions, go round pumping up all the tyres before you do anything. This will warm you up enough to carry out even the most miserable of repair jobs 

When working in the freezing cold just close the doors and get a heater!!
Then leave your spanners on top of the heater keeping your hands warm when used!
If car is running warm it up before you work on it that way the engine heat will keep you warm.
Wear a wooly hat!
Wear latex gloves they keep your hands just above freezing point!
I didn't like to say, but the man is definitely in the minority there!That's all well and good, assuming
a) you have an enclosed area/garage to work in
b) the car is capable of running.
well it was 2.5 degrees C here today according to my fully working temp sensor![]()

with gloves you don't always get the sense of feeling you need.
