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.

How to flush heater core after stop leak was put into radiator


undo the both heater hoses at the engine fire wall
turn the heater control on
apply a garden hose at one of the hoses and flush through
do it both ways
Two things to consider
stop leak should only work at the area of the leak and circulate normally with the coolant so there should not be a blockage
second point is , if the heater core is blocked then flushing will hot clear it and it may need a new core
It is known that some stop leaks affect the coolant control tap of the heater so it may be that control unit that is the problem and not the core so keep that in mind before replacing the core

Heater core leaking


When the heater core leaks engine coolant, the sure way to fix it is to replace the core. It is a small raidator made much like the engine radiator. You can try radiator "Stop Leak". If it is a very small leak you may get lucky with the stop leak for a while. Sooner or later the core will need replacing.

Thanks for using FixYa.

Coolent leaking from rear of engine can not see from where. When I stopped the car the fluid kept coming out. Engine overheated, I checked the front hoses they are dry and no leak from the radiator. What...


You could have a leak coming from the intake or even the heads. Before digging into those difficult items, I'd check all of your freeze plugs for damage/wear/rust/leaks.

Need to know where to put stop leak into my radiator


first off i dont advise using this type product, but i know it isnt always convenient to buy a 2 r 3 hundred dollar radiator, but anyway, with the car cool remove the radiator cap and let the car run about 4 or 5 minutes and pour it directly in the radiator and replace the cap, you will then need to drive the car an additional 15 or 20 minutes for it to take effect, i would replace the radiator asap, asit could cause it to overheat and cost tons of time and money,GOOD LUCK!

1992 volvo 960 radiator leak heater core leak We put Stop Leak but it's still leaking.


leak stop is just a temporary remedy, figure out why its leaking its probably that your radiator core is completely corroded thats why its leaking as well as the heater core. that require a little excercise taking it off, removing the corroded part or pipe and replace. if your radiator is aluminum or plastic that needs complete replacement.

I put stop leak in radiator and now the car blows cold air vs hot air when running the heater. why?


The stop leak have restricted the coolant flow to your heater core. You can try flushing out the Stop leak with Preston Radiator flush or replace the heater core. Once Cooling system flushed out, replace thermostat, radiator cap and repair coolant leak. Good luck and hope this helps, and Note: Common Black kitchen Pepper does great as a radiator stop leak without leaving any residue and can be cleaned out of the system with water and not coolant flush. Two table spoon is more then enough to stop a small leak. Good luck and keep me posted friend.

I have a 92 mazda mx3 that i just replaced my water pump on and we thought my radiator was leaking so we put radiator stop leak in and right after that my heater stopped working the heater was working fine...


the stop leak has clogged your heater core. you may be able to flush it out if there is still some flow, otherwise heater core will need to come out.

The heat in my jeep grand cherokee is not working


This is a common problem with Jeeps this age. Since there's no Heater Control Valve running down the hoses through the firewall, the heat is controlled through what's called the Blend-Air Door which is operative for if it failed completely, you would still have air deflected to the windshield. A thermostat isn't always the cure especially on these models. What you appear to have is a stopped up Heater Core. As long as you don't have a green liquid on the passenger floorboard, contact a local radiator shop and find out the cost to disconnect the two heater hoses from the Thermostat housing and "back-flush" them with air and water until everything runs clear. Don't use a chemical cleaner for if your heater core is weak, it could eventually start leaking and costing you an arm and a leg in labor costs to remove and re-install a new one. At times the no heat problem on Jeeps is that at one point or another, someone dumped a form of Stop-Leak into your cooling system. NEVER do that for the heater core is the 1st thing to stop up. Use regular pepper out of your kitchen for a quick fix should you develop a leak, for that can be flushed out easily whereas Stop-Leak turns into a mud-like substance. If you do have a hose leaking, then unscrew the radiator cap one notch to keep the 18 pounds of pressure off the hose until you can find a suitable place of repair.
