Heater core or something else?

Posted
  • Staff

 I've had a heater core leak before (different vehicle) so I'm familiar with the signs.

 The heater core in my '01 3500 has me questioning it. When I turn on the heater I will slowly get a fog on the inside of the windshield, then eventually on the door glass but I do not smell coolant. If I crack the windows and turn off the heater the fog will go away after a few minutes and leave no slimy film like coolant would. 

 I don't have any leaks on the floor either. I don't want to do a heater core right now. I would rather accumulate what I need to do the heater core, a/c coil and replace dash board top all at once. Probably about a $500 ordeal. I also don't like to use alumiseal or other cooling system sealers unless absolutely nessesary.

 I should also mention that the heater does blow hot air. 

 Any advise here? Is it for sure my core? Should I try a sealant for a temporary fix for now?

Can you share what filter you used.

 

Here is the filter and housing assembly.  I use a Napa 4070 filter replacement.  The filter housing is quality and one of the things I really like about the mounting is that two bolts can be removed and the whole assembly can be swung out of the way without disconnecting hoses to get access to other stuff.

 

I purchased the assembly from Pure Diesel Power.

     Thanks for the link IBMoblie. I'll add that to the list.

     Heater core is now bypassed. Just used one of the existing heater hoses to do it. I'll replace them both when I do the repair.

    NAPA part # is 9808 for preformed heater hoses. Both are the same.

    This is on my 02.

    Just an FYI
