No stop leak.

No stop leak.

Any questions?

 

Mine is showing the telltale signs of fog on windshield and Coolant scent when turning on heat.
Is this clearly a heater core issue?
If so, are there new and improved easy ways to fix it?

 

the only way to fix it, is to replace it....no easy out here

 

Any particular core I should seek out or avoid?

 

1. Yes.
2. No.

 

Of course it would have to be that way
Will any old autozone heater core suffice?
Should I also replace the a/c evap?

 

1. Yes.
2. Yes.
3. Yes.

Might as well do the evap while you're in there. It adds a few bucks to the project, but you really don't want to have to do it again for a while.

 

You're right about that, thanks!

 

I was hoping to get on it today or tomorrow while I'm off but I was able to order a core and evaporater shipped from rockauto for less than a condenser alone at autozone.

 

Before anyone starts pulling the heater core. If the hoses are tight against the firewall make sure they aren't leaking into the interior. They do get old and soft/rot. Seen this a few times. Can't hurt to check.

 

Might seem obvious, but if you haven't already, pull your air filter and make sure you don't have any coolant in the box.

 

Soft hoses look good and no fluid in the air box. What's that about by the way? Never heard of that.

 

Air enters the box (under the filter) right behind the rad cap and hoses. If coolant gets splashed/leaks around there it can make it's way into the box pretty easy. Found this out after a coolant flush by a sloppy mechanic once. Had fumes in the cab with the air on, found a puddle in the box, wiped it out, put it a new filter, and the smell went away. Sounds like you've got something else going on, but never hurts to check the simple stuff before tearing into a job. Good luck!

 

Thanks
Ah man, never wished for fluid in my airbox until now. Oh well, parts are incoming. I'm not the most patient. Hopefully I won't destroy something in the process.

 

Old plastic gets brittle. Lots of fun. Sometimes heat helps, sometimes not.
