In todays winter tech tip episode , we hit a mix of critical cold - weather checks that every driver needs to tackle before the snow flies. From tire pressures dropping like a stone in the cold, to fluids that turn to molasses if they 're old or low, to that exhaust system hanging on by a prayer - we're covering it all. If your fluids are tired , your tire pressures are low, or your exhaust pipe is one snowbank away from sounding like the local pizza delivery guy...then this episode is for you. Winter exposes every week link in a vehicle, and roadside assistance is a whole lot less fun when you're freezing for hours waiting for someone to save you.

This episode is about protecting your safety  ...
