I had a problem with bad heat, My T in the hoses doesn't have the restrictor in it so I am getting a GM one. My heatercore hoses were top hot bottom cold, I pulled them and flush them and blew it out with compressed air no hesitation or crap at all came out. I then looked at the hoses and the top one went into the metal pipe in the side of the motor and the top went into the plastic T, so my dad said they were probly crossed. i swaped them anyway and well I have better heat, not great but better.
Before the top rad hose was hot and the botom cold, now the botom hot and when the T stat opens top is hot, heatercore hoses are hot also. Does anyone have a hose diagram.

Re: Were my heatercore hoses crossed?
I am not sure what the stock "T" looks like. I assumed the one in the pic is stock but could be wrong. It should have a restricor in one leg though, or you won't get any heat. You could even make a restrictor for that mater.
