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

Diagram for replacing the heater core in my 2007 Dodge Grande Caravan SE? Strong smell of Radiator Fluid. No obvious leaks, smell stronger when using defrost. Passenger side carpet is not...


Sorry no pictures
Replacing the Front Heater Core in a 2006 Dodge Caravan.
1 Turn the steering wheel so that the wheels point straight forward.
2 Disconnect the negative (black) battery cable.
3 Drain the coolant by twisting open the valve at the bottom of the radiator. Use a clean container that holds at least 10.5 quarts. You will reuse the coolant later.
4 Remove the panel on the lower left side of the steering column and disconnect the parking brake cable with a pair of pliers.
5 Unscrew the 10 bolts that connect the steering column cover liner to the instrument panel and remove the cover.
6 Turn the key to the LOCK position and turn the steering wheel to the LOCKED position.
7 Unhook the gear shift cable and remove its mounting bracket.
8 Unscrew the two screws that connect the bezel to the instrument panel and remove the retaining clips. Remove the bezel.
9 Remove the two screws that connect the steering column shroud to the column and remove the shroud.
10 Remove the coupler from the steering column and intermediate steering shaft.
11 Loosen the nuts that connect the lower steering column mounting bracket, but do not remove them. Completely remove the two nuts and washers from the upper bracket.
12 Pull out the steering column.
13 Remove the interconnect and bracket that connects the instrument panel to the chassis wiring.
14 Remove the boot from the bottom of the steering shaft.
15 Use locking pliers to pinch off the heater hoses in the engine compartment. Remove the plate covering the heater core (the hoses run through it) and disconnect the hoses.
16 Unclip the connectors that hold in the heater core. Lift the accelerator pedal to enable you to slide the heater core out part way. Press the brake pedal to make room to completely remove the heater core.
17 Replace the heater core. Installation is the reverse of removal. The nuts on the steering column mounting bracket should be torqued to 105 ft. lbs. Torque the pinch bolt on the coupler to 21 ft. lbs.

Have 2004 jeep ckerokee and ac smells like antifreeze. there is water coming out of drain hose and out of bottom of the heater core cover onto floor. do you thing this is a heater core problem.


If there is coolant coming out then YES, try blocking the heater hoses,(disconnect at the engine and loop it back to the other heater hose outlet on the engine) this way you can be sure it is leaking.
To many times removing from the heater hose from the heater core inlets will break the inlet tubes.

Just bought truck. Heater hose shorted from pump to return (heater not hooked up) Is there a special valve in supply or return line or is pump supply just hooked to bottom heater fitting, and return...


be careful ! usually when people do that its because the heater core is leaking and they bypass it with the hose so if you hook it back up you might have a mess inside of truck !

I have anti-freeze leaking from somewhere near the back and bottom of the motor, not sure if it is exactly the motor or a fluid line or what...what could the problem be?


Well fortunately core/freeze plugs rarely leak anymore so the most likely cause of your leak is a heater hose at the passenger side firewall. Place a piece of clean cardboard under the area and run the engine. Watch closely the two heater hoses coming from the heater control valve and into the firewall(heater core), I'm sure you will find your leak up there. Thanks, Dana

Describe how to bypass a heater core in a 97 Dodge Dakota plz.


Easiest way to bypass a heater core is to disconnect both inlet and outlet hoses at the engine firewall. Install a right angle hose coupling in each hose. Then install a straight piece of hose to connect the two hoses.

97 gmc heater core diagram paid out the nose to have heater core replaced. began leaking 6months after. dont beleive its the core but one of the hoses coming to or from. Need to know how much of my dash i...


the hoses end at the firewall to the best of my knowledge. They have to be serviced from the engine compartment. The heater is another matter. Many of the old GM Truck products could have the heater replaced without pulling the dashboard. I would go to the local parts store & buy a repair manual on that truck for about $25 then check your hoses, then check the heater core. you can always by-pass the heater core by splicing the 2 heater hoses together with a $3 plastic hose repair kit & a couple of hose clamps. as long as the hoses are long and supple enough & not short or stiff & cracking. you can actually hear old hoses crackle when you pinch them between thumb and forefinger gently. replace as needed

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.
