What size is the intake and output heater hoses?what size pipe to rerout it.

Posted by on

  • Richard Scordino Mar 23, 2011

    Hoses generally have the size printed on them. Most common is 5/8 and 3/4 inch. if you want to bypass the heater core, disconnect both hoses that go to it and install a four inch piece of half inch copper pipe between them. If the hoses are too large for the pipe just tighten the clamps tight and it won't leak. (use strap type clamps)

Not exactly sure on the size but if you reroute it you will no longer have heat in the vehicle. If heat is not a concern all you have to do is find the two hoses going into the firewall and unhook them than hook them together basically by doing this you are bypassing the heater core altogether and just running the coolant right back to the engine. Like I said this will keep the car running but you will have no heat.

How do I keep the heater hose pipe that goes to the lower intake from coming out on start up there is no clamp it just bolts to the head ?


Buick heater hose fittings, the metal pipes that go into the lower intake, do have a bolt to hold them in, but also a rubber O-ring around the metal fitting so it won't leak.

I have a 1988 Lincoln Towncar. I am replacing the water pump, thermostat and associated hoses. It looks like the previous owner or someone before me replaced hoses at some point. However it looks like...


The bypass hose is usually different sizes on each end.
And the other small hose is usually a heater hose. It may go to the heater core, a control valve, or a metal pipe from the intake.
On some models the second tube is capped.

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

I am seeing water behind the pump on the top of the motor in the v under all the fuel injection / intake is that normal for water pump to leak there if its bad?


its not normal. the water pump will leak in front, not back. There is a pipe and hose down in the VEE that can leak. If the pipe is bad, you will need to remove the pump to replace it. The intake manifold will need to come off, to replace the pipe/ hose. the hose connects a pipe behind the water pump to a pipe at the rear of the block to a heater hose.

Radiator hose connection to the heater broke off.


HI,
THIS WOULD BE FINE IF IT WAS LIKE HOT OUT BUT NOW ITS COLD! SORRY TO HEAR THIS IT HAS HAPPEN MANY TIME TO ME THEY JUST GET OLD AND DETERIORATE VERY BAD DESIGN! OK SO WHAT YOU NEED TO DO TO FIX IT TILL YOU CAN REPLACE THE HEATER CORE IS BYPASS THE HEATER CORE. JUST REROUTE THE HEATER HOSE SO THAT IT COMES OUT OF THE WATER PUMP AND STRAIT TO THE INTAKE MANIFOLD PORT. SO YOU WILL ONLY NEED THE ONE HOSE AND TWO CLAMPS TO MAKE IT WORK. THEN TOP OFF WITH WATER AND MOVE ON TILL YOU GET IT FIXED RIGHT. CHEERS!

I HAVE A 1998 CADILLAC DEVILLE AND NEED TO REPLACE A HEATER CORE TO RADIATOR MOLDED PIPE. HOW DO I DO IT MYSELF? CAN IT BE MODIFIED?


Modification done by inserting generic T fitting into 3 way junction (Heater Core, Water pump, Surge tank) and using heater hose instead of pipe. Bye the way; the return pipe from the surge tank was not leaking so I did not bother to replace that pipe. I am watching the hose to make sure that pressurization swelling does not cause chaffing of the hose. The original replacement pipe was $80 and this modification is a fraction of that cost. The labor savings is significantly more important & valuable since this pipe requires the engine to be dropped (cradle installation) in order to remove and reroute the pipes from the firewall side of the Northstar V-8. There are two hard to reach attachments on the block that make it a maintenance nightmare. The resultant elevation of the hose to the surge tank and back does not inhibit surge tank functioning, at least not at this writing. I am keeping a close eye on everything. Experimental, but very doable fix.
