Please Help: R33 Coolant In Footwell

[SargeRX8]

I have no idea where its coming from. There is some coolant like substance(not dense like oil, but oiler than water and well, its green) in the passenger footwell and some in the driver footwell. If I lift up my floor mats, the bottom of them show signs of moisture. The shit doesn't dry up that well because its slightly oily.

The heater core has a leak in it but it has been blocked off a very long time ago. I have vacuumed and blown the remaining coolant out of the heater core a while back. Its not water because it hasn't rained.

How can I narrow this down? What are the entry points for coolant in the cabin apart from the heater? Is it in the air con system? Where is the air con drip thing? Could that be leaking into the car?

Has to be your air con man, that is the only coolant, infact the only liquid in cab (except sunroof drain pipes).

Remove your lower trim, then your main dash is held in via 6 screws (easy, having a mate helps to get it out around the steering wheel, but can be done alone), and check and tighen up all your pipes.

its the heater unit. i found this thread so you can see exactly what you are looking for and what is leaking. It will be the mini radiator looking thing and is very common for leaking and also hard too get too. Your going too have too break the holder of the radiator if you want to change it without taking the whole dash out and secure it in after its changed so it wont move or take it out removing the WHOLE dash

In the mean time you will have too bypass the two hoses (heater hoses) running into the firewall if you want to be safe, and make sure no one turns the heater on if you do not want too bypass the hoses.
