Frost plug type or in line coolant?

Which one?

Most reliable that I have been around were the block heaters. They circulate by convection. Down side is when have to replace one you will have to drain a lot of coolant.

This truck don't have one. But it needs one now that it's in a colder state!

I've never installed one. So looking for opinions on type of them.

I'll drain the coolant if I have to!

I've got a couple magnet type. Didn't seem to hold in cold temp vs real block heater.

Maybe mine are just not getting enough?

What motor in that brian.

yep, magnet on pan

I have an in line 1000w 120v, on my diesel tractor. Have on a timer, it comes on about an hour before , I usually start and stays on for 2 hours. Makes startup easy. old243

must be a cummins look at the front bottom of the oil cooler should be a plug there to take a heater

I run the block heater in my 2000 7.3. I also use battery blankets on both batteries when it gets real cold. I am lazy and just leave it plugged in over night when it starts dropping below 0. Been able to start it at -45 a few years back. I have a buddy that used to work oil fields in ND and got a brand new Dodge. He had block heater, coolant heater, fuel heater , and battery blankets. Said it was the best thing he ever did. Get in and already warm air blowing.

Block heater Brian !!

Another route in ADDITION to block heater is a quick drain on the oil. Drain it into a 2 gallon can at night and put it on the stove in the morning. Pouring HOT oil into that engine makes a huge difference.

I like 2 freeze plug-type block heaters, plus heating pads glued to oil pan and transmission pan, (if automatic), and either battery blanket or trickle charger. I also run synthetic fluids. Works for me.

I also support the freeze plug block heater. Helps tremendously also if you can park it inside a building.

I would definitely go with a frost plug type. The oil being warm helps, but if the cylinders are warm it's better for a diesel.

Holds 5 gallons of oil

That's my thoughts

It is nice to have warm air on start up! Not to worried about batteries. But I am worried about hydraulics.

I picked up 100 clients in a week two years ago due to bigger companies not being able to start trucks. Then not being able to run once they got them started because hydraulics were frozen!!!!

I was just running Ford 350s with 6.0 at the time and had block heaters. So no big deal here! But the bigger companies didn't get some areas picked up for 6 weeks!

I don't even wanna entertain that thought!

I'll wrap the hydraulic tanks and cylinder s with blankets on the bad days!
