Winter Fluid Recommendation

Like I said, many times now, it won't hurt but you don't necessarily NEED it. Fun fact: at -64, not much wants to start. However, -64 is pretty extreme, even for Alaska.

 

Definitely, get a block heater. And the cardboard in front of the radiator is a great idea. I only used to do the cardboard thing when it got below 20F, same for plugging in the block heater.
My recommendation with the cardboard, is only cover half of your radiator. You still want some air flow. Just cut a piece wide enough to cover half (right, left, center, doesn't matter) and have it tall enough that you can easily remove it when it warms back up. I just cut a piece that's too long, drop it in and trim it off so it's sticking out the top about 1/2". I don't know how easy that will be to do with the Taco but always did it with my old T-100. It will help you with cab heat too.

 

My advice is as good, or worthless as what anybody else will tell you:
I have lived my entire life in states where the weather is cold (many times very cold approaching -30 F). My experience is that as long as your antifreeze and battery are good you are good to go. Turn the key, if the truck starts you will be fine. Let the truck warm up a few minutes if very cold, but other than that wait about 30-60 seconds and drive away. Don't jump on the highway immediatly, but give the truck a few miles to get warm on minor roads. Slow driving is the best engine warmer and puts much less wear & tear on the engine than idling. My worst experience was when I had a car with manual transmission and it would not shift, or shifted very hard due to the cold weather thickening the clutch fluid.
Don't get your panties in a twist about this. There are tens of thousands of Tacomas in cold weather states. They are driven every day without issue.

 

Although a little off topic you should think about safety things to carry in very cold weather in your truck. Especially if driving outside cities. I don’t live in a cold climate but travel in winter to some very inhospitable places. For example some of the things I carry is extra clothing. I carry all year around a very warm water proof hunting parka. Also extra pair of socks, a warm hat with ear coverings and other things. I also carry water, a blanket, flashlights and xtra batteries, emergency flashing light and several other items. I won’t go into all of it now but I’m sure others will chime in.
One last thing batteries tend to crap out in really hot weather and really cold weather. Especially in cold weather. Check your battery often during the cold winter. If you have concerns replace the battery, don’t mess around with that.
