My van is hard to start at cold temps. It is -20F here today. I have a recirc pump, oil pan heater and two battery blankets on the vehicle. It also has a blanket on the hood to keep the heat in. I think my glow plugs need to be replaced. I am new to diesels. Are my glow plugs under the valve covers?

She will chug a little (like once) when I try to start her. But it is so cold I loose battery power quickly. So I keep starting over. I have a charger on the batteries.

I am thinking that the fuel is so cold that it won't ignite, and some/all the plugs are bad, compounding the problem. Is this a reasonable guess? I will replace the plugs, but I'm not quite sure where they are, as I have seen comments about them possibly being under the valve covers. Not looking foward to that in this weather, but whatever it takes........

Gotta get it goin in Alaska

The glow plugs are in the heads just INBOARD of the valve covers. The POWERSTROKE engines have them under the valve covers. You will need to find ZD-9 glow plugs. DO NOT use autolite...BERU are the best so they say, I have Wellmans from Here and have no complaints. Make sure to use anti sieze on the threads. Are you using any diesel fuel additives?
