See what your rad fan is doing with setting at heat, not defrost. It should only come on when temp gauge gets up around operating temperature.

How do I change my heater core in my 1996 ford ranger


The heater core is located in the heater box, under the passenger side of the dash. Most FORD heater boxes are snap-clipped together, and if you remove the rear panel from the heater box, you will see the heater core...it looks like a smaller radiator...twist the heater hose off of the heater core (x2) from the engine side and gently remove the heater core from under the dash. When replacing the new heater core, be very careful re-installing new hoses to the core...it is a fragile thin metal that can leak almost instantly if tweaked too roughly...replace all parts in reverse order of removal.

I need to replace the heater core in my 1986 Ford Bronco 2. Are there instructions on line on how to do this?


under the dash on the pass side there is a large black plastic box. take out the 6 screws and pull off the cover. there is a wire attached to the top that controls a flap, that just lifts off. under the hood loosen and remove the 2 host clamps right at the firewall area. Push the metal tubes in to the firewall. Then reach back in from under the dash and pull out the old core. put the new one in reverse order.

My 1996 jeep grand cherokee smell anifreez incar here water going back and worth but se no leak but have to re fill water once a weak.cant find leak under dash . but here water go back and forth wile...


the water sound i believe is from being low in antifreeze..if you are adding water oncce a week then there is a leak.. try looking on the inside of the car on the passenger side carpet to see if its wet..if not, then check things under the hood such as, heater hoses for heater core, water pump, thermostat housing, radiator, core plugs, block heater..if the smell is coming from the inside and there is a film on the window, then chances are you need a heater core....try that.
