You can remove the heater hoses and run one hose to each fitting on the engine. You may need an adapter if the hoses are a different size.

SOURCE: Leaking heater core

Yup, I've done the same thing before. You have to just find a tube of some sort that is small enough to fit inside the hose's going to and from the heater core. Remove both hoses from the heater core, insert the tube into the hoses and put some clamps on both sides nice and tight! Good luck

SOURCE: Leaking heater core

did u replace the heater hoses as well. When u run your ac an idle up valve raises your rpms slightly whitch will pump more coolant. Other than that they should have nothing to do with one another.

SOURCE: rear heater not getting hot

Hi:
Your vehicle only has one set of connections to the heating system, and you disconnected them when you bypassed the heater core. There is not a seperate heater core for the rear heat, just ducts off of the front heat.

Why doesmy nissan 2000/3.3heatup after bypass heater core


By-passing the heater core should not affect engine temperature much if any. Why did you by-pass the heater core? Leak?

I had to bypass my heater core. I snaked a hose from the input pipe around the motor and tied back in at the thermostat BYPASS HOUSING. I started with a 5/8 hose piece to a 3/4 elbow back to a 5/8 hose...


Was the heater core leaking? Have you checked your thermostat? By passing a leaking core should stop a running hot problem if that was your only leak. Does your cooling fan come on? Has the car been run extremely hot?

It is geting water inth air and ventilation system and throw it ina the cab


It's most likely a heater core leak. Hot radiator fluid is passed through the inside of the heater core, and air is passed over that. if there is a pin-hole leak in the radiator core, then it will come out of the vents. Turning off the heat setting will not change the leak either, it will still leak and collect in the lowest spot, and then blow out the vents when it strikes the fan impeller blades. the heater core is fed from 2 smaller radiator hoses. If you look under the hood, you'll see 2 large hoses that come out of the radiator. you'll also see 2 smaller hoses that go back towards the front of your car through the firewall. these 2 little hoses go to your heater core. Most cars require dash removal to change out the heater core. Unless you are pretty handy, I'd leave this one to the shop.

Nebraskadad2007@live.com. I bypassed my heater core till I'm able to get a new one but something is still leakin inside the van on both sides in front. Any ideas what to do or look for?


If you by-pass heater core, there's is no more coolant going into the dash (heater core), could just be left over coolant in a/c-heater housing, when it was leaking.There's nothing else under the dash the used cooling to work, but heater core, and that's by-pass.

Heater no longer works leaked inside under dash


The leak inside under the dash means that your heater core is leaking and needs to be replaced or by-passed. But by-passing it will leave you with no heater. You didnt mention the year of your truck but most likely you will have to pull the dash out to replace the heater core.

I have a leak on the front heater core. I waned


One hose takes the fluid into the core and one takes it out. Find them, disconnect them from the core and splice them together and the core is by-passed.

Its leaking water from the fire wall and steams up insiide thre car


either the heater core has sprung a leak, or the hose and its discharge is shooting inside the passenger compartment.my bet is on the heater core.you can by-pass the heater core.
remove both hose's that go to heater core and connect hoses with a piece of tubing, or make a loop with on hose to connect both water outlets .
