If it is anything like my 93, your heater hoses run from the heatercore through your firewall. Mine is located in the center most are located on the passenger side. Pop your hood look at your firewall you should see two hoses relatively close together coming out of it, those should be your heater hoses, and they are a pain. I'm trying to get them on the new heater core now...
You've got radiator hoses, heater hoses, power steering hoses, vacuum line hoses, etc. Probably best if you purchased a shop repair manual for that vehicle to show how/where they are routed.
Chevy Ventures have two heater hoses. One is located on the intake connection and the other located on the output connection.

The heater core is located under the dash board, all you have to do is disconect the heater hoses then unbolt the consol and slide it back far enought to be able to unbole the heater core and slide it out. The install is just reversed from removal. Joe
Before changing the radiator on a 2001 Pontiac Montana the coolant must first be drained. After the drain remove the radiator mounts, fans, and hoses. Pull the radiator upwards.
