Block Heaters

[Mikes96Z71]

How many of you use your block heater? I didn't know I had one until I traced a coolant leak to the block heater. Going to install the new one today after I get some sleep. I've heard good and bad things about them. Not sure I can trust any of the things I've heard about them causing problems with radiators.

My thoughts on these, they're just warming up the coolant to keep the engine warm in the winter. (Easier starts) I'm not sure how much electricity these consume but I can't imagine its very much with such a little calrod.

Sucks I have to drain all the coolant out to change it but at least I know when it was changed last and that it will be the right mix for winter.

they have there advantages. the block style uses less electric but takes longer. I like the thermo syphon type. if you put it on a timer for 3hrs before you need it in the morning it helps. Never had any radiator problems because of them

I have never heard of one cause radiator problems either. I will say this, They do consume quite a bit of energy. If you use a timer or not you still need a good drop cord. I would say nothing less than a 12/3 cord. I have heard stories of the cords overheating and catching on fire because they were to small or to small for the length needed...

I haven't heard of the thermo syphon type. I'll plug it in at work for my whole shift (3 to midnight) Use their power

Good tip on the extension cord. I've got some heavy duty ones that are also made for cold weather.

I use mine when the temp goes below 10*F and I have never had a problem. I have heard of problems with them but it has always been traced back to poor cooling system maintenance.

here is an example as it heats it pushes the colant thru the system

if you all you need is 10 ft, you might be able to drop down to 14. being ext cords usually start at 25 and go up, you will need the extra size to carry the current or you will either burn up your cord or cause failure to the heating portion of the block.
