How to retain heater core?

I've been looking at the coolant routing between the EG and RSX. I just want to confirm I've got this right...

So, with the K20 installed, the coolant should run from the driver side of the head to the passenger side opening with the valve which I believe is the inlet.

The outlet (driver side opening of heater core) should be routed to the hard metal tube that goes to the thermostat, right?

Anyway, I just want to know as I don't want to lose any of the luxuries my car has to offer. :)

Thanks for the confirmation. Now, I just got to find radiator hoses for the whole thing... Hope it's pretty straightforward.

Anybody have the needed length of the hoses? Both are the same inner diameter, right?

mine are gone... :( I think... Hmm. Maybe I better check.

Do you have any air bubbles in the system? If you leave the car running for about 20-30 min with the rad cap off you should be able to get all the air out if you have any in there. You may want to check your water to coolant mixture because that can effect the heat transfer through the system. Also make sure all the lines are connected correctly and that coolant is flowing in and out of the heater core. Make sure the valve is opening too. :wink:
