T/Atime

I don't winter drive my car but I'm wondering how cold is too cold??
I have a l98 with a coolant by-pass on the tb and a 160 t-stat.

This is the first year I have the privilege of storing my car in my new garage so I'd like to take it off the road only when the snow falls.

I've never had any issues with my car around freezing temps... I make sure I warm up the car in the driveway till its at operating temp.

Living where you do I think a 160 stat is a bad choice

All a lower stat does is means the engine takes longer to heat up ;more wear on the engine , worse fuel economy and longer for your heater to work
It doesn't change how hot it gets

All the TB heating is for is to stop the TB butterflies freezing in the open position , has no effect on engine operation

thanks for the link ^ btw.
I did read the link about different temps affecting the engine in different ways.

warm up time between a 160 vs 180 is about a minute or two if the car is sitting in the driveway in cool weather. cool weather is only a few times a year.... after my 160 opens up its just like all the other t-stats right???
they say 160 does nothing to keep it cool... just affects warm up.

I do believe a 180 is the correct unit and I do believe 160 has no real benefits over a 180. but my car has a 160 installed along with a tune that works great with the 160. the car runs nice and cool all summer. where I live is irrelevant because all its ever exposed to is -1.

thanks again for the link. I do remember reading this a few years back. good info but don't think its a 100% true. both sides have great points.

back to the coolant by pass affecting the butterflies. how cold does it have to be to cause problems? anyone?

It is not just "how cold"
The air has to have a certain humidity for there to be enough moisture in it to freeze solid from the cooling effect of passing over the TB blades.

Very cold " dry " air would have little effect
