Do a little research on the hose first. Some are preformed and they resist kinking better than a straight universal hose that may be harder to bend into place.

If you do this repair with the engine cold it will save you some antifreeze. There will still be leakage but less than on a warm engine. After you have the new part, cut off the old hose and it will be easier to remove the hose clamps.

Hopefully the original spring clamp will be on the hose ends. Do not use the screw type clamp as they always have uneven pressure. Slip off the hose clamp by squeezing the tabs and once removed slit the old hose to keep from being rough on the metal parts that you must remove the hose from.

Sometimes a little water to lube the new hose will help the new hose slip over the metal fixtures.

Hope this helps.

SOURCE: how to replace a 1991 Lincoln Towncar heater core?

wow. just did this one today. all i can say is have patience. you just have to take the dash completly apart top to bottom. you have to lower your steering colume to. you dont have to take the dash out of the car when you get it off enough on the passanger side just tie it up to the handle at the roof and you got access to the black box on the passanger side. you have to go under the hood and remove two bolts and two hoses to release the black box so you can get the heater core out. you also dont want to forget to disconnect the battery and drain your radiator. I watched my husban do this and i dont know how else to explain this or give better detail i hope i helped.

SOURCE: How to replace heater core

If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

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

How do i bypass the heater core of my lincoln towncar

On the firewall you will see where the water hoses go into the firewall. One is an intake and one is an output. When the car is cooled down remove the clamps on both hoses and get a proper sized strait adapter and a couple new clamps and clamp the hoses on the new adapter. The car will not be effected you will just not have any heat in the car.

I have a lincoln towncar 1994 4.6L v8....................where exactly is the heater control valve located on the car. I have looked eveywhere on the firewall didnt see a thing.

Might not be on the firewall, but if you trace the upper heater hose from the firewall to the engine you should see it, unless perhaps a previous owner had it removed. It looks something like this:

93 lincoln town car coolant leak from rear of motor

Instead of removing the intake manifold and the the leaky manifold coolant hose, we simple place a 1" dia hose about 3" long with a **** down it so it can fit around the leaky coolant hose with two hose clamps and an agressive amount of "right stuff" silicone sealant and let stand for 24hrs which should fix the problem

93 lincoln town car leaking antifreeze down back of engine

there is a small heater hose on the pass side rear from the firewall(heater core) to the intake manifold. the plastic manifolds have a tendency to split where the hose fitting goes into the intake. If that is where it is leaking the manifold needs replacement.

If you have a pipe leaking you need to replace it. Only onei can think of thats close to intake is the In/out to heater matrix.

But if its leaking from waterpump it need a new gasket.
