Question about 1990 Chevrolet K1500

1 Answer

Heater hose The heater hose that goes to the engine needed replacing due to a leak at the connection at the engine end. I removed the clamp from the heater coil end but when I inspected the other end (withe the metal tubing)and where it connects to the engine something felt loose when I moved it it broke off at the engine. It looked like a 3/4 size connector that screwed into the engine manifold behind the carb. I have tried an easy out but it will not budge the remainder of it and actually it is just tearing out whats left of the connector. Any suggestions?

I'd probably remove intake manifold, then get the piece out, so you don't have to worry about junk getting into the engine.
If that is a pipe thread in the manifold, then it should be easy. You may have to dress up the threads. They have fittings that have a pipe thread on one end and a hose fitting on it, then use heater hose from one fitting to the next. In the olds days the didn't have that metal tubing, they just had heater hoses.
In the past, I have removed stuck fitting from aluminum head. I got it out but I tore up the threads, I don't remember how I fixed it, too many years ago.
Of course I can't see anything from here. Use your best judgement.

SOURCE: Heater hose connector broken off in intake

If you had a welder you could slide the bolt into the hole tack weld it on and that tap lightly with a hammer and turn it out with the bolt. You want the bolt to be 3 or 4 inches long and just slide in one weld on each side and you should get it to come out.

SOURCE: The heater core tube comimg out of the firewall

if there is enough pipe left sticking out you can saw off the jagged end and jubilee clip/circlip the hose back onto the pipe, if the pipe is very smooth then sand it with sandpaper to give the pipe something to grip onto when you tighten the clip.
If there is not enough pipe sticking out... could you take a photo of it and email the pic to - I can advise properly then.

SOURCE: 95 Camaro Z28 appears to be leaking antifreeze

if your rubber hoses are cracked and leaking then replace the hoses with proper size and length.
if the hoses are leaking where they connect to the metal fittings from the heater core then try and tighten up the hose clamps -- they could just be loose.

SOURCE: I own a 1996 bereft

there is a small metal radiator, called a heater core, which sits inside the car. air is blown over it to provide heat inside the car. it is connected to the cooling jacket of the engine by two rubber hoses, one to bring hot coolant in and the other to return warm coolant back. either you have a leak in the core or a heater hose, from your description i cannot tell which. if it is a hose it will be a very cheap part to replace and a short bit of labor. if it is the core it will be much more expensive. i would find someone who knows the difference to take a look at it, probably not a good idea to drive it in its current condition. if it is a bad core, a short pipe can be put in place between the hoses to take the place of the leaking core until you can get it fixed. abot 90% of all the jeeps i ever rode in had this as a permanent fix for a leaking core but it is very cold in the winter.

Heater hose busted on my 2001 Montana van

If it's a heater hose, it will go to the firewall behind engine, where it connects to the heater core's fitting that juts out from firewall. Hose goes over that fitting. Heater hoses are fairly easy to replace, maybe not so easy on yours, due to lack of space. Drain the coolant before taking off hose, loosen clamps on it, then start pulling it off. Watch for a hose holding bracket that also needs to be removed before hose is completely free. Some do, some don't have such a bracket. Hire a neighborhood kid that works on cars to replace it, as sometimes that hose to heater core fitting can get stuck on tight, and if one starts yanking or pulling on it, you can break the fitting and will then need a new heater core-big expense to replace. Good luck and merry christmas in capital letters, lol.

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.
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 you replace the heater core in a 1984 GMC 3500 camper

You will probably need new heater hose...first check heater hoses that run from engine to the
heater core......Most hoses will tear at the end where they are connected to the core and at the engine...First mark where each hose goes then drain coolant from system and remove both hoses...Take old hose's to parts store and get new hose's and clamps...They should be dryrotted
by the year of vehicle....It is easy to bend or break new core so be very careful when installing new core....After removing old hose's from core under hood you will know the location of the core....
remove screws under passenger side dash to remove core from inside of dash...very simple very easy....It looks like a tiny radiator with an in and an out spout...dont forget to mark where hoses
connect before removal.......Be sure and refill with new coolant/clamps/hoses because of age of vehicle...Both heater hose's that connect to the core are connected at the firewall on the passenger side of the engine...The core fits into the firewall dash and is connected to an input and an output hose...THIS IS EASY FOR BEGINNERS BUT BE CAREFUL WITH NEW CORE NOT TO BEND !!

I have a coolant hose that comes out from the engine block and goes towards the cab which is leaking. the hose has a screw type finding into the block

If the hose comes from the engine and goes to the firewall it is most likely a heater core hose. If it's a rubber hose with clamps on each end it should be fairly easy to replace by lossening the clamps and fitting a correct size new hose in it's place.

Antifreeze leaking on inside passenger side of 1994 GMC suburban

It sounds like you probably have a leak in your heater core. Replacing a heater core can be a difficult job. If you decide want to try it I suggest you get a shop manual to help you out. I can give you a relatively easy temporary fix that will stop the leak until you have more time to fix it or you can take it into a shop to have it done. The down side is this fix will temporally disable your heater. Wait for the engine to cool. Open the engine compartment and look all the way in the back between the engine and the firewall. Find the 2 heater hoses that pass through the firewall. They should be about 1 inch in diameter. Undo the hose clamps and disconnect them from the firewall. Get a short piece of metal tubing about the thickness of the inner diameter of the hoses. Use this metal tubing to connect the heater hoses together and clamp them using the two hose clamps. Now the antifreeze that would normally circulate through your heater core will instead circulate through this loop and not enter the passenger compartment. If you can't find a short piece of metal tubing to do this fix you can completely remove one of the heater hoses. Then take the other heater hose and connect it to location near the engine where you disconnected the first hose. Save the first hose so you can hook it up later when you do the more permanent fix. Make sure to position all hoses such that they aren't resting on any hot surfaces. I hope this advice helps you out.

Leaking coolant water

This L shaped hose is a drainage for the heater core compartment. Once we removed the panel to the heater core it was obvious the heater core was leaking into this compartment. We changed the heater core out and the problem has been solved :)
