Block heater

[HarvestingInternationally]

Hey guys I don't think my block heater is working. I left my truck plugged in for about 6 hours and I go start it ; the ECT was 20 and EOT was 18. What do u look for? Fuses? Relay? Where's the heater itself? Thanks. It's been in the low teens here...with wind chill in the negatives.

Check the wires above the plug. I just had to replace my plug end as one wire was broke.

They get worn out after a while.

The block heater screws into the passenger side of the block. It's usually the cord that takes a crap.

Dumb question but are you sure that outlet works? It's happened to me where I thought things were broken, went out and bought new ones only to realize that it was the outlet and the old thing worked fine

^ thanks how long does it normally take to heat the truck up with it plugged in

[amdriven2liv]

I started this when the temp was 39f just to see how well they worked.


1 hour later it was 80 degrees.

2 hours later was 94 degrees.

3 hours later it was 103 degrees.

4 hours later it was 110 degrees.

5 hours later it was 116 degrees.

And here is a thread with input from other members here on temps they see.

Block Heater Temps...by the hour.

I guess "how long" also depends on "how cold". I plug my truck in most nights. It was 7 degrees here this morning when I started my truck, By the time my Edge Insight booted up the reading for ECT was 102. Haven't had the Insight long but so far ECT has never been much over this even after heating for 8 or 10 hrs.

You probably don't need to do the whole cord, just the plug end. Last one that went out on me I didn't even check the wiring, I just cut the end off and put a new plug on it and was back in business. Of the four block heaters that have quit on me all of them have been the plug.
