SOURCE: Where is the heater core hose in my 2000 ford expedition?

check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

SOURCE: 98 Expedition coolant leak top back of engin

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

Mitsubishi montero 2003 leaking anifreeze in the rear

There is a set of two steel pipes that carry coolant/antifreeze to the rear mounted heater core for heater operation. These steel pipes/tubes rust out, and you end up with a coolant leak. Mitsubishi has superceded the steel tubes with aluminum tube set. Not an easy job to replace the two pipes since they are routed over and around a few items under the vehicle before attaching to the heater core at the r/r of the vehicle.

Heater not blowing heat only cold

Check the coolant level. It is common for the intake gaskets to leak causing the coolant level to drop. The first thing to stop working when the coolant gets low is the heater. Top off the coolant and determine where you are leaking coolant whether it be the intake gaskets, hoses, radiator, water pump, etc.

If the coolant is full what does the temp gauge say? Once the vehicle is warmed up it should read around the 200 degree mark. If its below 190 than the t-stat is stuck open. Replace the thermostat.

If both of those are fine and the coolant looks like mud than your heater core is plugged. You can try back flushing it with a water hose. Remove both of the heater core hose and use a water hose to flush out the heater core. This may take several tries before you start to feel some heat.

Car is leaking coolant from a rubber L shape pipe coming out of the fire wall

The L shaped pipe you are talking about is the drain tube to your heater box for the airconditioning. In the same box is the heater core that carries antifreeze for the heater. If there is coolant leaking from the drain then the heater core is leaking and needs to be changed.

My 89 chevy caprice with a 305 is leaking antifreeze from the back of my firewall (passenger side) onto the exhaust pipe. It is dripping onto the exhaust just past where the two exhaust pipes come together...

Check the heater control valve and the hoses where they go into the firewall. If the leak is not there, then the most likely problem is a leaking heater core. You need to look carefully to find the source of the leak before you can repair it. Use a flashlight, mirror or whatever is necessary to do that. If it is a hose, use extreme care removing it from the heater core connection. best to cut it off with a razor blade. If it is the heater core,most times it will make the passenger side rug wet. If it is the core, it isn't an easy job and I'd consider either getting a haynes or chilton manual to guide you, or, have a good shop do the work.
good luck

Water leak on passenger floorboard also an ac problem

probably leaking heater core. you may have low coolant level now. the only place water comes in the cabin is for the heater, that has got to be it. the heater core can be bypassed (like my car's is) by simply cutting the hose that leads into the car and leave about a foot, make a big U out of it and plug the other side of the hose into the coolant passage that returns from the heater core and leads into the intake manifold. pretty easy you will need a knife, hose clamps, and common sense. the third one is a little harder to come by! :)

Leaking coolant on the intake manifold

Clean off the motor as well as possible check to see if it is leaking from the front or rear where the manifold connects to the motor also check to see if there is any leaking on the inside of your truck to see if your heater core is leaking also check all hoses and clamps also on those there is connection that comes out of the heater core to the intake that is plastic and are prone to leaking and braking
