Block Heater warm up time
How long does it take for the block heater to warm up a 7.3? I live in Minnesota and was thinking about installing a timer in our garage that would start the heaters about 3 AM giving them about 3-4 hours to warm the block. Our garage isn't heated or inulated but it is attached to the house so temps usually never get below zero with doors closed.

Dan,
I installed a circulatiing block heater on mine that will melt the snow off my hood in about 1 hr. They're nice cause you don't have to have it plugged in for very long (I use a timer on mine) and they will warm up your block enough that so that when you start your engine, you almost instantaneously have heat blowing through your heater. They're fairly inexpensive from most farm supply stores and IMO, they're worth their weight in gold (especially up here in Canada). They do suck back the power when run (I installed a 2000watt unit), but as I said, you only have to run them for about an hour or so (depending on the outside ambient temp). At -30 degrees C, 1 hour is sufficient. Hope this helps!

Circulating block heater
Does anyone know who makes a circulating block heater? How much do they cost? Thanks

In Central Washington we only get to maybe 5-15 degrees at night. Is it a bad thing to leave it running all night, other than the additional power drain reflected on my power bill?

I paid $60.00 Canadian for mine from a farm supply store (thats roughly $45.00 US). I don't recall who it is made by, but I do know that it's well made and fairly heavy duty. Hope that helps.

if we ever have that kind of weather.....you're diesel not starting won't be your main problem
it would be like all the Northerner's die when they have the heat waves of 85. We'd have no water, no food, no roads....life as we know it would end until it hit the mid 20's again.

Block heater warm up time
Hello higa2000, One more question. Which heater hose and where abouts on it did you mount this heater? When I look at my heater hose area there is not much room because of the heater box. Thanks in advance.

Ed,
I have mine mounted on very lowest point on the corner of the front passenger side of the engine (right beside the camshaft position sensor). It's a pretty tight squeeze but it fits. The unit itself sits vertical with about 2-3 " of hose connecting the bottom of it to a coolant drain plug opening (that's right, you have to drain your coolant). Then the outlet is connected with approx. 2-3 ft of hose that runs up until it connects via a "Y" into the return line from the engine block to the heater core (you can recognize the return line as the one that is also connected to the front passenger side of the engine). It's fairly important to mount the unit as low as possible so as to allow the unit to heat the coolant from the lowest part of the engine and allow it to migrate upwards (high school physics - heat rises). Then I have the electrical cord run straight out and through one of the holes in the bumper. I'd post some pictures if I had a digital camera, but I don't. But trust me, it works pretty slick. Hope this helps!
