Sounds like a heater core seal busted, check if you got water leaking into the passengers floor. If so, you got a bad heater core

likely you have a blown head gasket or crack in head. Though common, this condition does not always show up in engine oil. To verify, have a shop do a hydrocarbon test on radiator.

Coolant line under intake is leaking 95 town car


95 Lincoln town car coolant leak under intake SOLUTION EASY

Ok this is a 4" piece of hose leaking on a tube that runs under the intake manifold and fastens to the rear of the engine with 2 small bolts that are very hard to get to. The heater core hooks up to this tube with a 5/8 hose that's 3/4 on the other end going into the heatrer core.
Solution:
remove alternator
see clamp on hose?
remove it.
If you can't remove it, clamp vice grips on it and take a steak knife and cut through the hose towards the rear of the engine. Now with large screw driver pry the hose and clamp off the nub on the rear of the water pump housing. You may have to move the tube and remaining hose out of the way first. Just stick your hands in there and force it out of the way. Now you have a clean nub to hook a 5/8 bypass hose to. Here's where you get it. Go back to the heater core and and remove the hose that connects to this tube that runs under the intake. Just cut it where it hooks to the tube and remove it carefully from the heater core because this is now your needed bypass hose. Now with a couple feet of 3/4 hose and a coupler you have all you need to reroute this water outlet around the engine to the heater core. Take your hose you cut from the other end of the tube and removed from the heater core and and fasten it to the nub on water pump housing use new screw type stainless Steel clamps. You have to take this one apart to put it on. Stick a 3/4 coupler into the other end and route a long section of 3/4 hose under alternator to the heater core using SS clamps where needed. job done... Just leave the old tube where it is under the intake manifold......Thank you Very Much

Few days ago cavalier decided to empty coolant out of its tank and overheat. we since then took compressor off serpentine belt changed thermostat checked oil for water flushed system checked fan heater...


Water pump. The impeller can come loose from the shaft and not circulate enough coolant. These can throw you off, because when you remove the pump the impeller will be tight against the shaft. It is when they warm up they begin to slip. If the heater core is not leaking don't bypass it.

Water leaking onto passenger side floorboard,soaking the carpet


Your heater core has developed a leak - the wetness on the passenger side carpet is engine coolant
from a heater core leak, or a leak in one of the two hoses connected to the back of the heater core.
Your strategy: disassemble dash down to heater core, determine whether you'll need a new heater
core or new hose (or new hose clamp), then replace the offending part.

Water leaking out of overflow from heater core.


If coolant is leaking from the heater core into the interior or through a weep hole out of the car your heater core has sprung a leak.
Most vehicles have easily accessible heater cores, only requiring removal of a panel under the dash or hood to gain access. On the '97 Skylark it's accessible under the dash.
  • Disconnect the negative battery cable.
  • Drain and recycle the engine coolant.
  • Raise and safely support the front of the vehicle.
  • Detach the drain tube, then disconnect the heater hoses from the core tubes.
  • Carefully lower the vehicle.
  • Remove the console if equipped.
  • Unfasten and remove the sound insulators, console extensions and/or steering column filler, as required.
  • Remove the floor or console outlet ductwork and hoses.
  • Remove the heater core access cover.
  • Unfasten the heater core mounting clamps/bolts, then extract the heater core from the vehicle.


To install:
  • Install the heater core, then secure using the clamps/bolts.
  • Fasten the heater core cover.
  • Connect the outlet hoses and ducts.
  • Install the sound insulators, console extensions and/or steering column filler.
  • Raise and safely support the vehicle.
  • Install the drain tube and connect the heater hoses to the core tubes.
  • Carefully lower the vehicle.
  • Connect the negative battery cable.
  • Fill cooling system and check for leaks. Start the engine and allow to come to normal operating temperature. Recheck for leaks and check coolant level. Add if necessary.

Waterleaking passenger floor all wet!!! where is the heater coil and can i by pass it


call any auto parts store to find exact location of heater core. yes you can bypass it, but you will have no heat inside of car, it needs to be replaced. to bypass just hook hoses from core together, without going through heater core.

Heater core


If anti-freeze is actually coming out of the drain tube then yes, you could very well have a bad heater core. You may also be able to smell antifreeze while inside the vehicle if it is leaking. [Its a kind of sickly sweet smell] If just clear water is dripping out then this is most likely from normal condensation that is collecting and dripping off of the air conditioning evaporator core as the air conditioner runs. This condensation collects in the heater, a/c housing then drips out of the same little drain. Water from normal condensation will evaporate off of cement or pavement pretty quickly but antifreeze takes quite a while to evaporate away and feels slimy to the touch. It doesn't take much of an antifreeze leak before the cooling system gets low on so make sure you don't run low on coolant which can cause the engine to overheat.

Leak in tube that feeds heater core


What would cause it to leak is corrosion if it is a metal line. If it is rubber, it is just age. If it is metal, I would recommend draining the coolant and replacing it with fresh as it may have become acidic and will cause you more problems in the future -- and that motor has a large metal coolant line under the plenum feeding the back of the water pump. Good luck.

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.
