Starting in Cold Weather 850 T5...[ALL/1988] posted by han 850T5 on

Just wondering if anyone had any problems starting their 850's in cold weather (I mean COLD below freezing). I went to Mammoth early this month and after I came back from a day of skiing, my car took a few lazy seconds to crank up. Same happened the next morning. Is this normal or is my battery going? I read in a post recently about a dead 2 year old battery. Could this be happening to me? Now I'm back in sunny Los Angeles and the T5 starts well, but sometimes it crancks for a couple secs before starting. I think this is pretty normal, but in the cold, I was kind of surprised and concerned.
thanks,
han.

I was told that the ecu will allow a turbocharged 850 to crank for up to TEN SECONDS, giving much needed oil(and pressure) to the turbo and its related plumbing, before the coil kicks in. If you don't believe me, check your owners manual. I'm reasonably certain it tells you about cranking time.

How cold do you consider Cold?
And the big question... what weight oil are you running?
Part of the problem may not be your battery but just the fact that your
running a heavier weight oil that in LA is the right viscosity but when
your in cold weather the oil is a lot thicker which can help make the engine
crank slower... You'd be surprised the difference in cranking at
-25 below Zero if you have an engine block heater plugged in and if you dont.
and basically the only difference is the temp of the oil.
Vehicles that I have had without block heaters will crank slowly,
If a Block Heater is plugged in they usually crank right over.
