There are two hoses that connect to the heater core, and they are located next to the brake master cylinder, on the driver side of the van.
I believe the bottom hose is the inlet and the top hose is the outlet.
Good Luck, Greg
The heater inlet hose is on the firewall. On the 2002 Silverado it is close to the bottom of the firewall on the passenger side.
The heater inlet hose on a 92 Geo Metro is located in the rear of the engine compartment. It runs through the firewall and connects to the heater.
its located on the heater core
Heater core? Inlet or outlet hose fitting at heater core?
On a 1997 Chevy truck, the heater hoses connect to the heater core, which is located inside the dashboard. The two hoses run from the engine's water pump and thermostat housing to the firewall, where they connect to the inlet and outlet ports of the heater core. Typically, the hose coming from the engine connects to the inlet side of the heater core, while the other hose returns to the engine's cooling system. Always ensure the connections are secure to prevent leaks.
No it will not, it will just back flush the heater core and clean it out.
The outlet from the 350 engine to feed the heater core would be the one closest to the thermostat.
On the firewall, under the hood, you will find the inlet and outlet hoses.
Start the truck. Turn on the heater. Hold both hoses in your hands. The first one to feel warm is the inlet.
in the carb inlet
Run your vehicle with the heater on. Let it warm up. Shut it off, then open up your hood. You'll see two heater hoses running into the firewall. The hot one will be your inlet line.
The thermostat on a Chevy 2.2 engine should be located under the top hose inlet. The top hose as well as the inlet need to be removed to get to the thermostat.
