so heres my problem. block heater quit working in my '97 ctd. i can not get the old block heater out of the block. i have tried every trick i know with no luck. i did get it to turn about 1/4 inch but can not get it out. not sure what to try next, looking for suggestions. the block heater leaks coolant so it has to come out. any help would be great.

 

Did you loosen the allan headed bolt in the center of the heater?
The heater isn't threaded it, the allan bolt causes it to expand and seal when tightened.
Perhaps you may not even need to remove it, just tighten the bolt to stop the leaking.

 

there was no bolt going through the block heater. ive change several block heaters on other vehicles and have never seen one like this. it has to be changed, the block heater doesnt work. ive heard some heaters have springs holding them in but have never seen one.

 

hi
poast a detailed picture and maby someone can help ?
otherwise my guess would be to somehow carefully cut it up to get it out ?

 

ill try to get a pic tomorow. thinking i'm gonna have to pull turbo so i can get at it better then go from there. cutting it out may be the only option

 

keep unscrewing,it will come out if it looks like this

I agree. I had an old Block heater I used in my parts washer to heat it up. It screwed in.

 

finially got it out. it was in the frost plug hole so i knew it had to come out one way or the other. finally got a hole drilled through it and got a punch wedged in it. then with the help of a cheater bar on the end of the punch it finaly came out. heres a pic in case someone else runs into the same thing. ive never seen another heater like it. thanks for all the tips.

 

Wow, that's different. Looks like it has a c clip on it!!!

 

it did, one behind each of the "star" washers

 

so how the heck did it get installed in the first place? Mini workers crawling inside of the water jacket?

what year of truck was that installed into?

 

What he said!

 

97 3500 4x4. judging by the looks of the heater it must be driven into the frost plug hole. once the washers go through the block they would catch and not let the heater come out. thats my guess by looking at it, but not positive. like i said before, i've never seen anything like it and neither has anyone i've shown it to. makes for a good conversation piece though.

 

I may have the same thing going on here.

Has anybody ever seen a block heater like this? Anybody know how to remove one of these? I have search the web high and low and cannot find anything like it.
