Detroit Cold Weather Starting Dave G 10-21-02  
It took a lot of cranking to get my 1975 6N71 Detroit started this morning. About 30 degrees ambient. 2 amp charger on the batteries all nite. I'm afraid that drop another 30 dergrees and she won't start at all. The bus has sanders and electric mirrors, but I can not find any engine heater. So my question is what type of heater to install? Sources of energy are electric (land line or genset), propane (100 lb tank) or fuel oil. Should I attempt to heat the engine oil, the fuel oil, the intake air, or the engine coolant? Or should I try to inject some sort of starting fuel? Or is she just a good time in the summer time gal?
And, if she can't be started for the winter, should I do anything special to mothball it? The morning temps are not going to be consistently above freezing here again until April 2003.

The best way is a "block" heater. That heats the coolant in the engine block. You can leave it plugged in all night, or put a timer on it. Do you need to run it frequently?
Re: Detroit Cold Weather Starting Dave G 10-22-02  
Well, I'd like to take it out for a 50 - 100 mile ride every couple of weeks.
Is a block heater something that I can install? Same as a automobile or something special / bigger?
I filled with fuel last weekend. Should I add anything to it for cold weather (or any other reason)?
Re: Detroit Cold Weather Starting Joe 10-22-02  
You could add good fuel conditioner, like "Siloo" to it once following the instructions closely. Depending on how cold it gets where you are, you may also want to put an anti-gel additive in it also.

OK, I found a JJeb block heater, old but unused, for $10.00.
Part JLR842000-120V. 2000W
It says it fits Detroit N71 A & B, blower left side.
My 1975 Crown has a 6N71...but the blower is on top(?)
Would this heater fit?
Re: Detroit Cold Weather Starting Joe 10-22-02  
The heater would probably fit into one of the water outlets on the block. The blower has nothing to do with it. There usually is a plug in the water jacket that has the same size threads as the heater. Without seeing the heater, I can't tell you where it goes. One place is on the middle rear of the left side of the block. Another fits into the water jacket by the water pump.
