location for block heater?

Does anyone know which freeze plug to put a block heater in a 2002 3.4L tacoma?

 

What about useing a lower radiator hose heater, instead. Less likely to leak and if so an easier fix.

 

Another option is to get a magnetic block heater. They're great because you can put them on your oil pan. I'd rather have warm oil than warm coolant if i had to choose one. A guy can always add more than one if want, one on the oil pan and one on the side of the block.

 

directly above the engine oil cooler...

 

My block heater fell out...I was lucky I noticed the steam and pulled over right away before all the coolant drained and my engine overheated...

 

I've seen block heaters put in different frost plugs, I personally chose the one easiest to access (through the wheel well drivers side). I also put a pad heater on my oil pan, as well as underneath the battery. I used RTV and duct tape to secure the pad heater to the oil pan (worked like a champ).

If you are running on temps into the negatives, I would spring for oilpan, transmission, block, and battery heaters (I live in Fairbanks, and that's pretty much the standard install up here).

I've also seen guys hook up trickle chargers to their batteries as well, and yea it's needed when the temp dips below -40

Hope this helped.

 

Thanks for the info. I bought this truck in anch, where it was babied in a garage and warm anch weather. I intend to put this truck to the test in the cold cruel world of North Pole and plug it in outside like a real truck. I've already installed an oil pan heater and a battery trickle charger. Now it seems the best advice to go through the wheel well for a block heater. Access is certianly the issue. In regards to a circulating heater in line with the cooant hoses, I think that it would use more electricity. It would probably work best with a timer.
