does anyone have anything on getting to the heater core...?

Shottas

do you mean the blower motor and sensor for your heat and fans?
under your glove box take off the panel and its like 4 screws to your fan and your cabin filter is in there too

The actuall heater core i'm smelling a leak (very distink smell only when heats on ) when the heats on i gotta check the actual core

MBtech1098

Dash has to come out, cross brace needs to come out, ac needs to be evacuated, coolant drained or clamped off, remove hvac box and seperate.

yeayea i'm talkin the easy way not the junior memeber MBtech way...

And what i mean by that is i think theres lines going into the heater core All i wana do is check the lines going in and out...

rude is my nature...

dont take it personal

MBtech1098

Aight mista I wanna be a ganksta. What is it you want to check with the lines at the heater core? If they are leaking. There is no easier way to R&I the heater core then what I explained.

That's what you pretty much gotta do. You can also clamp off the heater and just run without a heater...

Refrigerant and coolant have to distinct smells, evaporators are pretty common though

check the coolant lines that pass thru to the firewall area, there are some video's on how to find, clean, repair those 2 hoses, and the pass thru

Wow what an old thread, but maybe some one might learn something. Heater hose to the firewall broke (plastic connector). Leaked out all of the coolant and having to tow the car home. To repair and put back the hose looked difficult, if not expensive. Having to remove the dashboard and what not. It took me a while but I figured out where the other hose that led to the heater core was and was able to just bypass the heater core all together. Once I found it was basically a few minutes and done. Sure I have no heater, but I'm Miami I never would have to use it anyways.
