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: coolant leaking from two russted

Having enough room to hit the new freeze plug to install it is probably your biggest problem They make an expandable freeze plug which tightens with a socket, but aside from a hot block, I don't know how close to the exhaust manifold your freeze plugs are. An emergency repair may be to drain the antifreeze, clean and scuff the old freezeplug and try JB Weld. If you have a small leak after that, some radiator sealer may finish the job.

SOURCE: Heater core burned out and I want to bypass the coolant hoses.

Without knowing your car specifically I can suggest the generic way to do it. Locate the two heater hoses going into the firewall, probably on the passenger side. They're the ones that get hot and are about an inch + in diameter. Disconnect. Measure the inside diameter of the hose and purchase a short piece of galvanized or copper pipe (6 inches) at Home Depot. Connect both ends of the hoses to the pipe to form a loop. Secure the hoses so they don't land some place that would cause a problem.

I had this problem on an 85 Tbird. I had heard about a product called Bars Leak and tried it. It worked. No leaks and I kept my heater. You should be able to find it at any parts place at less than $10. Ground black pepper also has worked for me.

SOURCE: coolant leaking out of heater core drain tube

The core is bad. You're lucky you have a catchpan and drain in your car... most people end up with coolant all over their feet when this happens! You have a few options. 1. You can pick up a bottle of cooling system leak stopper (available at Wal Mart and auto parts stores), follow the directions and see if that stops the leaking. 2. You can cut the heater lines and bypass the core entirely (obviously this is only a good idea if you live in Arizona or some other warm place). 3. Replace the core.

1994 Caprice LS. Little to NO heat.


It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.

Coolant leaking somewhere unknown, have to add to reservoir every 3 days or so, strong antifreeze smell with a/c on. water sloshing sound in passenger side dashboard. bad heater core?


sound like a bad heater core! the heater core is like a small radiator that is usually locaded in the dashboard on the passenger side. now if the leaking is really bad you are going to see water dripping by the front passenger tire or if it gets really bad it may leak inside the car. in order to fix this problem the HEATER CORE must be replaced. good luck

The heater blows cool air not warm air


First check and make sure that your coolant(antifreeze) level is full, the hot coolant runs through the heater core and than air is blown over the heater core heating the air for the heater. if the coolant is full you than need to check the thermostat and make sure it is functioning properly. finally if both of those are not the problem it is possible that your heater core is bad, however if the heater core is bad you will notice coolant leaking onto the passenger side floor. so if the floor is dry I would say the heater core is not the problem

Getting water in front passenger floor boaed, what might cause it?


Clogged or disconnected drain hose from the heater core box. Or bad/leaking heater core. Does the liquid smell like coolant. If so bad heater core. If not and the water only when you use the AC then it is a drain hose issue. If neither of those pan out you could have a leaky windshield. However 99% of the time a wet passenger floor is caused by a bad heater core or drain hose.

I have a problem with my fire wall leaking coolant, it seems to be comming out of one of the hoses that lead to the heater core.but i have no loss of heat and i cant smell anything from the vents.and i was...


Do you have coolant on the front passenger floor board? When heater cores fail it will leak onto the floor board and mist coolant on the windshield. If you have a loose clamp on the heater core hose it's possible it could be leaking down the firewall into the passenger compartment. If you don't have coolant on the windshield check the clamps / hoses first.
