Does engine block heater keep coolant warm?

Oonrahn, it looks like an old appliance cord and might have been replaced at some point. As far as mfg, I wouldn't have a clue, but so long as it works, I'm not going to mess with it. I'll just keep an eye on it and not leave it plugged in when I'm away or asleep.

If that is a flat cord with the screw on 2 pin connecter at the heater it is factory they do get warm all the ones I have seen and fwiw they say don't leave plugged in for over 4 hrs in the book

That's exactly what it looks like. The pins were loose when I got the bus so I packed the connection in Hi-temp silicone to keep it tight and from rattling loose when the engine is running. But yeah, 4 hours will definitely heat the beast up.

Scott -

Our block heater will move the temp needle in 2-3 hours when below freezing.  Makes a huge difference starting the engine. 
The mechanic that installed it said he put in a 1500 watt heater.  I guess they come with different sized heating elements.  It warms our radiator and you can put your hand on the block and feel that its not cold.  The power cord also gets pretty soft.

The same mechanic also said its not good to run the engine with the block heater plugged in.  No idea why.  He mentioned it can ruin/short the block heater.

See you in a few.
