Does it make a difference that my truck is a 2500 instead of the 3500? are all block heaters coolant based or can they be oil pan?

Expert:  Dino replied 4 years ago.

yes the 3500 and 2500 are different.

here is the info for the 2500.

these are coolant heaters. thats the way almost all block heaters are designed

the info seems clear, the only thing i am wooried about is removing the engine mount. can you still remove the plug without taking off the engine mount.

Expert:  Dino replied 4 years ago.

this is something you have to look at. a lot of times the directions are over kill.

once you get a clearer view of the block heater you will see if this will come out with out removing the mount.

Customer: replied 4 years ago.

when draing the coolant system is there a seperate drain plug like the for the oil pan

 

Expert:  Dino replied 4 years ago.

if you see the image showing the block heater their is a bolt going into the block .

im not 100% if this is a block drain plug or not.

if not then you will have to remove the heater very slowly so it drains into a drain pan.

most of these blocks will not have a drain bolt.

this is the fun part of this job.

Customer: replied 4 years ago.

so the bolt is the only thing holding the plug in place? The plug doesn't unscrew as well

 

Expert:  Dino replied 4 years ago.

yes and the directions are telling you to twist and pull the heater out.

once you throughly read the directions it will be very clear
