I've got an 87 supra turbo, and I'm wanting to do a coolant system flush, and I've got the little flush kit, which as I understand I'm supposed to tap into the heater core inlet hose.

The only problem is, I don't know which hose that is!

I also might want to flush the heater core as well, in which case I need to know what the outlet hose is too.

Thanks!
