open up your hood, and look at the 2 heater hoses going into the fire wall (the ones made out of rubber) the aluminum ones are for the a/c. disconnect them i believe they are hose clamps with an 8 mm. go to auto zone and buy a heater core bypass kit. or a simple fitting to where you can connect both hoses. put a hose clamp on both sides so it doesn't leak. make sure the hoses aren't hanging down in the way of any thing. and you are done
In the a/c heater core housing under dash, pass. side
that model is acually located under the hood on the fire wall on pass side..
To remove the heater core you will need to pull down both pass and drivers side under dash, remove the three screws holding the fan blower in and remove the 8 remaing bolts holding up the heater core cover then you will need to remove the hose clip in side the box, pull both clamps off firewall remove heater hoses pull core, Install reverse order should take a hour and half start to finish make sure you vent coolant lines when you refill this info is for a 3.4 engine .Ed
On 83 heater core 4 or 6 nuts on fire wall under hood remove hoses go into pass side and remove glovebox if needed and disconnet cables and pull heatererore box out change heat core
Remove your heater hoses from the core (cut them if necessary) and join the two ends with a heater hose coupling. Use screw ring clamps to secure the lines to the coupling. You can pick up all these parts at any major autoparts store.
Tie the 2 water lines that run to heater core together
Could be several things. If the blower works on A/C or vent it is good. If the Heater core is not leaking (due to corrosion, which is a common problem) it is probably good. Could just be the Temperature cable is off the the blower door not allowing air to pass over the heater core. Just to name a few..........
Trapped air trying to pass thru the heater core. Check the coolant level, make sure it is full.
They usaually fog up the inside of the windshield when defrost is used, soak the pass side floor with coolant and smell of anti freeze when operating heater in any mode.
It depends what you define as easy, i changed one in a 1994 Chevy van and it was a pain in the ***. I don't know about ford but in the one i changed it had to come out from under the dash then I had to take the plastic casing off and it came right out. If you don't need the heater i would just by pass the heater core. All you have to do it take the hoses off the heater core and connect them together. That's way easier then replacing it. hope this helps.
Sure. You can by-pass the heater core but you won't have any heat for defrosting the windshield should you need it.
