Block Heater

[Cobrajet]

Just tested my block heater and it's shorted . I looked in
the service manual and it says you have to drain all of
the coolant. I would think I should just have to drain the
block??? also it seems like ebay has the best prices I can
find the dealer wants $160.00 and I can't find after market
so far thanks...

Waiiiiiiitttttt!!!!!
All you need is a cord. Did you ohm test the cord? I have heard of only one or two block heaters going bad. 99% of the time it is the cord. It gets broken inside from all the tugging and pulling. That is why I suggest the Marinco mod to stop this. Pics in my sig. The heater and cord are sold seperately so you aren't out anything by changing just the cord first.

How do you test the heater/cord? I'm wondering if mine is working or not-that could be another problem with these cold starts!

Bio,
You Ohm test the cord, between the two prongs, this is not your problem. You truck should start without a block heater down to 20 below. The heater just makes it easier and allows the heater to blow warm air quicker. Follow the troubleshooting I sent you and you will have your problem solved.

First, I plug it up and it doesn't throw the breaker in the shop. Second, I get in the truck the next morning and the heater blows warm as soon as I crank it. If it fails either test then there is a malfunction.

last night mine shots a blue flame about a foot long and the sparks were flying...lol the plug on the truck must have had a crack from being bent tugged etc... the wire couldn't take the power I'm assuming and it shorted out blew the breaker in the garage I just cut about 6" off the cord bought a new heavy duty water proof end and replaced it .. works like new again

I am replacing the plug on mine. There is one green wire and two seperate stranded wires. Is the green wire ground?

Did a search and read through some old threads...green wire is ground.

This site is sure helpful!
