I discovered a coolant leak from the connector that connects one of the heater core coolant supply lines. It has an o-ring inside of it that has deteriorated. Could some Me please tell me the size of the o-ring needed? The part is no. 6 on diagram.

I do not know, but here are a few of the better links to coolant issues. It might be in one of them. Look below where you found the picture. The parts should be listed there.

I do appreciate the effort but I checked those threads high and low and found nothing. Thought I'd ask as a last resort. Not much you can do when you are a victim of "turboless syndrome" lol. Not much input is available on these forums for the entry level non turbo versions of cars. Funny thing is this model has sold millions, so you mean to tell me out of all of those cars no one has faced this issue before? I'm all for using forums for the purpose of modding and upgrading a turbo car, but where does re average joe go who just wants his car running correctly so he can get to and from work etc?

Have you checked with your dealership parts department?

Did you ever find this and what happened?
