Block Heater

Where can I find out how to change out the block heater on my 01 power stroke? I have seen it before but can't seem to find it now. Where would be the best place to find a replacement one as I am positive that mine does not work at all? Had my truck plugged in all day and there is still frost around the heater. Thanks

The way I find out if the heater is working is when I pull out the plug, you get a spark. When plugging it in, the lights dim in the neighborhood (JK, but it does dim my lights slightly in the garage). Starts up better in the cold when plugged in. It -4*F right now (was almost +50*F yesterday evening) and I will find out how my 8 yr old batteries are holding up.

Sorry I do not know how to replace the heater, but someone will pop up with advice.

Dave..

Its just above the oil filter, mine just did the some thing but as I was about to take it out I discovered that it was just the cord. Must be the moisture or something caused it to burn where it screws on to the heater itself.

To replace heater:
- Wrap new heater from NAPA ($50, but you can find them cheaper other places probably. I never looked) with Tef-Tape*
- Get wrenches ready for BOTH heaters (sometimes they are different if different brands)*
- Unscrew old heater*
- Screw in new heater quickly as coolant will be splashing down on you.*
- Tighten tight but not too tight.*
- Run cord. (You can do this in the beginning too. If you do it in the beginning you will probably find a bad spot in the cord and you replaced the heater for nothing. This seems common to many around FTE)

*NOTE: This is not an FTE approved method for changing the block heater. A true FTE member would buy $200 worth of fancy no water, no silicone coolant. Drain the entire system. Dry everything with a blow drier to be sure all old coolant was out. Flush. Repeat drain and dry. Follow steps above. Then replace with new, "better" coolant.

I did mine using the above method. No draining. Be sure to leave the cap on as this is like pouring gas from the gas can w/o taking the vent cap off. It will drain MUCH slower.

To check the block heater I would:
1 - Take DMM (Digital Multimeter) set on Ohms and place leads on the two flats on the cord. It should read around 14 or 15 ohms. If 15, you win! Your block heater works. If 0 or far less than 14 go to step 2.
2 - Place DMM leads on each pin on block heater (it is located just above the oil filter). It should read around 14 or 15 ohms. If 15, you win! Your block heater is good, but your cord most likely has an issue. If not 14 or 15 ohms go to step 3.
3 - Inspect cord for major damage. If no major damage go to step 4.
4 - Find a buddy. Plug UNPLUGGED electric cord into block heater. Go under truck w DMM on 120 volts. Place leads in holes and have buddy plug it in. If you get 120v you don't really win! If you get less than 120 v you win a bit more. You can just get a new cord for the heater! (The bad news is the cord is only ten dollars cheaper than the whole heater assembly. Buy both and leave the heater sit for when that goes out.) I am not sure this step is necessary, but it is fun to try and zap yourself w 120.

I would look for freys and maybe try splicing in a new end before I went through the trouble of replacing the entire cord.

Also check your outlet to make sure its working and troubleshoot your extension cord.

Thanks guys for your response. I did check my heater and it is bad, reads nothing on my meter. Have a new one ready but not so sure I want to do this with snow flying and the wind blowing.

Are you SURE it's the heater and not the cord? That is, did you disconnect the cord from the heater and get down there and measure the resistance right on the terminals of the heater itself?

I just have a hard time believing that these heaters burn out. It appears that some people have had this happen, but I would put my money on the cord in 95% of the cases. Just trying to save you from a nasty repair job out in the blowing snow.

I did unplug it and checked the heater itself and it doesn't show anything. I too was hoping that it was just the cord, but no such luck.

Mine's been starting "cold" lately, even plugged in, is the block heater shot?

its -40, and still starts, so obviously it is working at least a little, but it seems like it used to start easier when plugged in.

When these block heater 'go', do they just not work anymore? or do they slowly stop working?

I thought that mine was working but until I crawled underneath and felt around the heater after it had been plugged in and it was still ice cold I knew that mine was toast.

I replaced mine today, that was not fun, not hard just not that much fun in the snow with coolant going everywhere.

Thanks for your help guys.
