when I first turn on my heat it smells like coolant, after running for a min it gos away. I have been checking the coolant and it has stayed the same. checked the heatercore and thats a ok. dont know what eles. thanks for any help.

 

Exactly how did you "check the heater core?"

 

I'm wondering the same thing. Unless you ripped apart your dash, I doubt you did justice on checking it. it probably has a small leak in it. Check again on the passenger side floor, check to see if it's wet at all.

 

The heater core may be just "starting" to fail and you might have the smell, but no actual wetness or significant drop in coolant level.

Sure does sound like the heater core though when you smell coolant inside the cab. Read up on the repair before digging in; it takes a while to complete and isn't much fun.

 

You could add some cooling system dye then run it for several days with the A/C on (to add water from the evaporator condensation) then check the drain hose from the HVAC box on the firewall with a UV light. That's the only way I can think of to "check the heater core".

Checked it by pressurized the system and trying to hear for leaks and checking the floor to make sure it was staying dry.

I doubt you would "hear" a leak of this nature. I agree with an earlier poster that it is probably just starting. At first, the coolant will just weep out and stick to the fins of the core.

As the air flows past it, it evaporates the coolant so that you can smell it. Later, your windshield will get a white fog-like deposit on it, starting where the defroster vents blow against the glass.

Just get ready. It is a very time-consuming repair to get to it. Don't use any radiator stop-leak, it will just clog the whole cooling system.

 

Ya that stop leak it nasty crap. Thanks for the help guys

 

ive been having the same issue for a couple of months now, i just need to go on and change it....

 

It's summer time.... you can bypass your heater core for a while if you don't want to do any more damage or smell any more coolant. It's a band-aid, but as mentioned, replacing the heater core is a PITA, so you can buy yourself some time to get motivated. Hell, maybe your A/C evaporator will go out too this summer and you can kill 2-birds and all...

 

You could flush the coolant and try adding one of these miracle liquids that seals the system, as a temporary measure.

I just replaced the heater core after a collant leak inthe cabin. Expensive and messy.

 

Did you not read my earlier post?

 

Have fun pullin' that dash... be sure to pick up some A/C disconnect tools before you get started!!!

 

Yeah.......... Don't do this
