86 Iroc Radiator Flush.

I have an 86 Iroc z with the 305 TPI. I bought a radiator flush kit but I cant seem to identify the heat inlet hose. I only see one that runs from the rad to some where the fire wall. The other only one that runs to the front of the engine is the large hose that connects to the thermo.

Any help would be appreciated.

Here is a pic. Is the hose connected to port 60 the one I need to splice and connect the waterhose to

?

port 60 and 61 are the heater core hoses.

Re: 86 Iroc Radiator Flush.

Hose #62 that connects to port 60 is the heater inlet hose. Taking out connector #67 will eliminate the need to splice into anything if you can fit the T fitting in there.
