The separation between the engine compartment, and you, is called the firewall. The Steering shaft, from your steering wheel runs through the firewall, the heater hoses run through the firewall, the power brake vacuum unit is connected to the firewall, your ignition wires etc run through the firewall.
the heater core hoses run into the car through the firewall behind the engine
If you look in the engine compartment , at the firewall , you will see where the ( 2 ) heater hoses run up to the firewall and connect to the heater core which is INSIDE the vehicle ( on the right side / passenger side )
find the two hoses that run from the engine block to the firewall, they should be about the thickness of a garden hose. Disconnect both of them from the firewall and connect them together. No water will ruin in to the heater core=no heat or leakage.
Your question makes no sense. Do you mean two hoses from the radiator to the engine? Two hoses from the firewall (thru which the two hoses access the heater) to the engine? What do you want to know, exactly. In either case that I mention, the two hoses are used for water/antifreeze mixture to circulate to the relevant parts.
I assume you are referring to between the engine and the firewall. There are 2 heater hoses in that location.
It is located at the back of the firewall behind the motor and it run under the distributor into the block. You actually have two hoses back there but it's the one running to the engine block.
Check if heater hoses were removed they run from the front of the engine to the firewall on the passenger side. Hope it helps
This fluid can leak from many places. Look in places where water hoses meet the engine, where the heater hoses go into the firewall, the radiator and your heater core.
At the back of the engine on the coolant outlet that goes to the heater hoses on the firewall.
Look at the firewall in the back of your engine compartment. You will see two water hoses come out . Unscrew and pull off both hoses. Get a garden hose and cut off metal fitting. Twist on garden hose on one of the pipes sticking out of the firewall. Run hose water through it for 5 minutes. Then repeat on other pipe .
-remove front seats-remove steering column-remove entire dash-remove heater hoses from engine side of firewall/bulkhead-remove A/C hoses from engine side of firewall/bulkhead-remove nuts holding heater / A/C box (on engine side of firewall/bulkhead)-remove heater / A/C box from cab side of firewall/bulkhead-remove top of heater / A/C box.-replace heater core
