Ok sooo i got my new motor in my truck today fired it up and i smell coolant from the fans soo im assuming the heatercore is broke is this a easy fix and step by instructions..Alsooo when the fan is on High its barley blowing then when i move it to a lower settin it doesnt even blow then what could this bee thanks for you time

 

If you scroll down the forum or use the "search" feature you will find your answer, I just posted it last week.

It is an easy fix, but it is intimidating if you have never done it before.

Sounds like blower is going out too, this isnt so easy of a fix.

 

i did search and couldnt find nothing whys the blower soo hard to fix just take off the cover under the hood u dont think its just the switch

 

Maybe your vacum lines are pinched? Or not cliped in all the way?
