I have never had a vehicle that had a plug-in for a heater in the engine. My question is when should it be plugged in? It's a 2005 PSD with 60k on it and I only drive it about once a month during the winter. It rarely gets below 27-32 degrees in the coldest times here in Central Texas. Should I leave it plugged in all the time when not in use?.....only at night when it gets below X degrees? Any help or advice is appreciated. Thanks.
I would suggest using a timer and setting it to come on 3or4 hours before you need the the truck. You can select the temp you want to use it but freezing (32*f) might be a good place to start. It's not going to hurt to use it or not outside of those parameters. But why pay for the electric if your not using the truck. If I remember right it's 1500w. Imagine how much you could light your place up with 15 100w light bulbs running around the clock. There's no thermostat feature so if it's plugged in- it's on.
Be sure to get a timer rated for that much current, and the extension cord too.
Also .... I'd drive it more than once a month if possible.
Seems that that advice is as valuable as getting a scanguage.... These things don't like to sit, and like to have the PIZZ run out of them once in awhile.... That's what I tell my wife as she's got the white knuckle grip on her sissy bar , hard to here the over the whistle
