My wife and I rarely take off with a cold engine even in the summer. I've always believed it was better for the engine to warm to operating temperature before applying all of the pressure and strain that is generated with normal engine operation. I think this is especially true with aluminum heads. Also, we don't believe in scraping ice or frost from the windows. Instead we start our vehicle and let them warm up to the point where the windows are defrosted. This said, several years ago when gas started reaching the $3 mark I started putting a small bathroom heater in the floorboard of the car on those cold nights and turned the thermostat on really low. I figured electricity was cheaper than gas. Now I know that does nothing for heating the motor, but it does eliminate the idling time to defrost the windows as well as not having an ice cold interior. I also ordered an alarm kit w/ remote start that will work w/ a stick shift. Four years later it is still sitting in my living room floor. I also ordered a ZEROSTART 1500 watt tank style heater. I've never installed it either. Do you have any suggestions about mounting the heater?
