Magnetic oil pan heater question

jhwis · Nov 24, 2023

Anybody in the cold weather areas use magnetic heaters that attach to the oil pan for helping start a diesel engine? I'm talking at 0 degrees and below. Northern Wisconsin.

Hello I have used a magnetic heater on the block they help some but they are nothing like a frost plug or a tank heater . Bryan central MN

The one tractor I use in Mn winter I keep in heated shop. If I do need to use another I turn the knipko on it for a couple hours. Worm everything not just the pan.

I used one on a B250 and It worked fine

I had one of those electric dip sticks. Worked pretty good.

I have 3 of the magnetic heaters gripping the side of my toolbox right now. They are only 200 watts each so not a lot of output. These come in handy if a block heater fails and something needs to start. Also thought they would work well to warm up gelling fuel in a steel tank. Have not used any lately but keep them handy in case. Also living in North Central Wis. Steve.

If you are going to be in side they will work decent if you use all 3 of them at once. IF outside or in an open sided shed. Put the block heater in. It will take less electric and work much better. In Mid M<I using heater for 30 years.

If I where you I'd stick it to the side of the block that way it heats the coolant instead of the oil

I have one on my CJ3 Jeep it is functional on that small engine, but 40% as good as a coolant heater. (also central MN) St Cloud. Jim

I have one, it's very handy. Our JD 4600 has a block heater, but since I run 15-40 oil if I need to start it in cold weather I put the magnetic heater on the oil pan along with the block heater. In a few hour it starts like summer, this is in an unheated garage I mile from the Canadian border.

them heaters are for the oil pan, stick one or two under the pan and heat rises. they dont work very good on the block, and yes i have 2 of them

I had to help start a school bus in cold weather. It had either a 6.9 or 7.3 International diesel engine in it. I used a cutting torch. Removed the air breather and lit the torch on gas only. Had the lady crank engine then held flame towards intake so it would suck the heat in. It fired right up with low batteries.

Yes, I used them for years until I got block heaters on everything I need to start in the winter.They work best if you put a heavy tarp over the hood. I used two on a IH M for years, One on the motor the other on the hydraulic tank for the Farmhand F10. I know cold weather as we normally have two to three weeks of -30f between November and April.

I have one that I use on the oil pan. They would work on the block if you could find a perfectly flat area large enough. You have to put it on way in advance.

They work well on keeping oil warm, not so much for coolant. They perform much better for retaining heat in the oil rather than trying heat already cold oil. We used a lot of them on hydraulic crane oil resovoirs, plug it in while oil is warm and it saved a lot pumps the next morning. We had some 2 cylinder air cooled Duetz diesel as well, and used the pan heaters on them as well.

Different approach Jim
choices

If water cooled, first choice should be the heater hose type that will circulate the warm water. Really nice to instantly have warm air from the cabin heater.

For air cooled your choices are those magnetic block/pan heaters.
Dipstick hole heaters and heat lamps also.
They also have wrap around and bottom of battery warmers.

Being able to cover the engine with canvas, tarps, blankets, etc. will make all of the above more effective. Any wind or free flow air movement is the enemy.

Will not make a much of difference in the starting . Need heat in the combustion chamber . However the engine will build oil pressure sooner after startup .

I never thought they would work that well & use block or an inline coolant heater. Then again, I haven't looked into them in a while.

The silicone pad heaters work well if you have enough room for a bigger one.

I put an immersion heater in the oil pan of the Deutz engine on my snowblower. Phillips/ Temro brand, it came with the bung to weld into the pan.
