The heater inlet hose on a 1999 Jeep Wrangler 4.0L is located in the left, rear of the engine compartment. It connects directly to the heater core which circulates heat throughout the cabin.
The heater inlet hose on a Hyundai Accent is in the back of the engine compartment. It goes through the firewall to the heater core.
The return hose for the heater core generally leads back the the water pump. The inlet for the heater core comes from the engine.
There are two heater core hose that goes to the firewall the inlet and outlet. through that hose, you will also have the rear heater core hose attached to a T joint in both the inlet and outlet hose. You splice the hose of the front heater core inlet and connect that to the rear heater core inlet hose. Same goes to the Outlet hose with the T joint using a conncetor which you can buy at your auto parts store, 3/4 inch size. Basically you are bypassing the front heater core that is connected to the firewall. You wont have any defroster and heater for the front, but the rear vents and control will have heat.
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.
On a 2003 Bonneville, the hose to the water pump that is the heater inlet hose is the top hose coming from the radiator. This is also the hose that holds the thermostat.
It should be the same as my 1995 - at the firewall the heater hose nearest the drivers side is the inlet hose to the heater core
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.
Start the truck. Turn on the heater. Hold both hoses in your hands. The first one to feel warm is the inlet.
its located on the heater core
It depends on the vehicle you have. In many cases (but not all) the inlet hose is smaller than the outlet hose.
Heater inlet hose on a 99 subaru legacy is on the passenger side coming out of the fire wall. One of only 2 hoses coming out of the fire wall.
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
