I plugged in the truck yesterday for the first time. water temperature was at 68 degrees. Does this sound about right for a truck that's been plugged in for a few hours?

--- Update to the previous post...

Sorry, 48 degrees. Not 68.

I am getting no where with this!Why would it matter if the block is warm or not, shouldn't it work regardless?The tests I did were performed lastnight, not this morning after I got home.I did a thorough inspection of the heater element and it was clean as can be. No signs of dirt, contamination, or anything of that sort. I am going to test the prongs on the heater element itself when I get home and see what I come up with. Anybody know what reading I should have, would it be the same reading of 20-21 ohms?

I just said this many posts ago. The element is 750 watts, which is 19.2 Ohms at 120V. If you are at 20.7 it is fine. You have to read the posts to get somewhere with this..

Actually, 19.2 Ohms is 750 watts. 20.7 works out to 695. So your element is fine. When you plug it in, it will sit there for a few seconds then you will hear it turn on. It isn't that loud so you can't hear it if there is any other noises around. If it were me, I would plug it in for an hour then feel the block right next to where the block heater goes into the block. It should be warm, if not, you got other issues going on.

If you still show a similar resistance on the prongs of the block heater element, that indicates that that element is good. I strongly suspect a bad cord. Just so I am follow your steps. You are allowing the block heater to be plugged in for at least 3 hours right? It takes a LONG time to warm up that much steel and iron. Some block heaters make the sizzling sound and some don't. After the block heater has been plugged in for about 3 hours, place you hand on the water neck on top of the engine. It should feel noticably warm to the touch and warmer than the rest of the engine.

I had it plugged in all day yesterday and it didn't warm up. Water temperature was at 23 degrees.I'm suspecting a bad cord as well. I will find out once I test the heater element.

Keep a spare cord and you will always have a known good unit to fall back on. Only takes a few minutes to test swap in a new cord and listen for the sizzle or crackling when you plug it in. Sometimes the connection between the cord prongs and the block heat prongs gets corroded or dirty and then gets very hot and in some cases can melt. This usually results in an inop. block heater.

Sorry I blew up on you guys yesterday. :(

:lmao::lmao2::lol: No problem. You should see me when I am having a bad day working on my truck other equipment. :mad@computer: I deplete the English language of cuss words and even invent a few new ones. Not doing real well on my New Year's Resolution. :doh:

LOL. That's funny, I invent new ones myself too. But, only I understand. LOL

Boy I know that feeling I have used some choice words on my truck over the last week or so.

LOL. That's funny, I invent new ones myself too. But, only I understand. LOL

So did you have a bad cord? I have found if it is working the entire engine is very warm to the touch. Made for a nice working environment to change my stock LP to the FASS DDRP-02, I will relocate when it is a bit nicer outside. :drool:

Well it's -4*F here this morning and with the truck plugged in all night the temp gauge read +140*F. Something you need to understand is this is nothing more then a small hot water tank heater. There is no thermostat on it so it draws power all the time it is plugged in. Also the coolant is not circulating it is just sitting there so it takes a long LONG time to heat all of the coolant. There are other block heaters that use a small pump to circulate the coolant to more effectively heat your coolant. You can also add a pump yourself then still us the stock block heater. BTW if you need a new cord set or heater element buy it off e-bay the cords are selling for $12-$15 and the dealers sell just the cord for $110+ :cookoo:. Here is a pic of the mod I did relocating my plug to the lower air dam. post-10751-138698175572_thumb.jpg post-10751-138698175563_thumb.jpg The part I used is from a marine supply house http://www.marinco.com/product/20-amp-125-volt-power-inlet-black keeps the cord set from hanging out from under the hood/grill. How do I post pics....help :ahhh::lmao:
