Question 05 sti coolant on floor board driver side

hey guys i have an 05 sti and the ac compressor started going bad the clutch wouldnt turn so i got rid of it last night just took it out temporarily. i also noticed before i changed it the ac vents were smoking and i kept smelling a funny smell which seemed like free on but not sure and then when i got out i noticed a puddle of green fluid by my feet and was slowly dripping down the side and when i wiped it was green...i dont know if this is the rest of the free on from the compressor lines or what it is? evaporator? suggestions? thanks

It could be the refrigerant if it had die in it. It could also be coolant if your heater core is leaking.

You have a cracked heater core.

I would suggest you search how to bypass it to save your head gaskets and lube your bumhole for what will be an expensive repair.

+3 for heater core.

Also, make sure you save that free on. On is not cheap, and most people have to pay for their on.

take your glove box out and see what is going on there....could be as simple a loose heater hose.

if your compressor indeed went bad, its generally from the intake valve on the pump being blocked.

this causes excess pressure to build in the system and rupture the evaporator that is in the cabin. it looks ALOT like the heater core, just has a couple copper tubes with thermistors on it.

I doubt the heater core is bad, that is directly behind your radio on the firewall inside the cabin.

the evaporator can be changed by just taking out your glove box, which will reveal a black box with a kinda roundish look to it. the evaporator will be inside that box.

I would however recommend taking your dash out to make it a hell of alot easier and you will be able ot clean up the excess

Cars haven't used freon in nearly 20 years. And R-134A isn't that expensive.

Anytime green **** pools in the cabin it's going to be the heater core.

When an ac system has a leak and we cant find it in the shop we add a die and it is green. If the ac has die in it then it would be green. So it could be ether one.

OP did you seriously freaking remove the A/C without having the system purged at a shop... That stuff can kill you. Why the hell do companies supply MSDS if no one bothers reading them..........

Are you guys serious? a shop will probably charge you like $50 to evacuate the system, well worth avoiding a serious health hazard.

At the very very very least I hope you both did it outside, doing it in a garage would deserve a quadruple face palm.

It's actually not that bad. Just cut the lines and go make a coffee, or something.

Did you read the MSDS? Unless you discharge in an extremely small enclosed area with yourself inside of it, it's not going to harm you. Even in a closed garage you are probably going to be fine.

Yes I did, I guess with people spraying brake clean in poorly vented garage spaces without wearing respirators the effects of r134a seem pretty minimal.

I still wouldn't recommend venting the refrigerant but I guess if that's the way you do things go for it! Hell run your car in the garage for a while and get some carbon monoxide going as well. That stuff doesn't kill people either!
