I cant begin to describe how to replace your heaters core however you can buy a repair manual at most any autoparts store for your 1985 Chevy Cavalier by Haynes or Chiltons that normally explains this procedure. (At Your Own Risk) As for bypassing the heaters core that's simple disconnect the two hoses from the core and install a coupling between the two simply making a loop or take one hose off completely and take the other hose off the heater core and run it to where you took the other hose off the engine either way you will be making a loop from point A to point B of your engine not the heater core.

Detach the screw that attaches the heater duct on a Chevy Cavalier and remove the heater core. Once this is done you can replace the faulty heater core with a functional one.
replace anti-freeze, replace thermostat
no , the heater core provides heat to the interior for the passengers
bypass the heater core by connecting the two heater hoses togethetr or replace heater core
To bypass the heater core you need to remove the two water hoses going through the firewall from the engine compartment to the heater core and connect them together so that the water loops around back to the engine.
Sounds like heater core is leaking, replace heater core or bypass
Take both heater hoses off at the heater and the hose running from the front, attach it to the rear of the engine.
Replacing the heater hose bypass fitting will depend on how the fitting was installed. It could be screwed or bolted in. Try searching for your specific vehicle for a detailed description of the install.
To bypass the heater corer in a Chevy Cavalier, disconnect the heater core hoses at the firewall. using a hose splice available at an auto parts, slide the hoses on the ends of the splice. tighten the hose clamps down. Check the coolant level in case it is low due to losing any during the procedure. Wash the ground thoroughly because any coolant left is toxic to animals.
Heater coolant bypass pipe It would be the return hose for the heater.
No , if you were to bypass the heater core , you would have no heat
heater core has a leak replace heater core
On the firewall, engine side, will be 2 hoses held onto the heater core pipes with clamps. Make sure the engine is cool, and get a bypass peice from your local Autozone, or what have you. Unscrew those clamps, and take the hoses off, then put the 2 hoses on the bypass pipe, and clamp back down. Do this only when the engine is cold. You will likely have to have the car up on jackstands, or wheel ramps. Its much easier to access the pipes from under the car. If you are tackling this job, you might just consider replacing the heater core while you are there. Its only about 30 mins more work, and is fairly easy. Best to grab a service manual for detailed instructions on this.
you probably have a leaking heater core....you can replace it or bypass it
If its just the cord, then follow the old cord to the back side of the engine ( really the side of the engine closest to the firewall ) and replace it. When the engine is cold, plug it in and you will hear the block heater heating up. If you don't hear anything, then replace the heater also. That requires a little more knowledge.
Yes, you can bypass the core. Find the hoses to the heater core. Remove them from the core ... as a worst case scenario, cut them. Install a double male hose connector with clamps on the hose ends to complete the bypass fix. . John In Montana
You have to pull the dash and all the lower fascia, then remove the box that houses the heater core. Take the clamps off the heater hoses from the engine compartment side of the firewall and disconnect the heater hoses. Disconnect the bracket that holds the heater core in place from the inside of the passenger compartment (if present.) Carefully remove the heater core and discard it. Install a new heater core reversing the above steps.
This is a common complaint with mk2 Golfs, most of which were fitted with a heater matrix bypass valves to prevent the heater matrix from bursting under certain conditions. These bypass valves can fail, cutting off supply to the heater matrix resulting in no heat. Either replace the valves or remove them and fit a heater matrix from a mk3 Golf. These are stronger units and don't require bypass valves.
If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )
There are several reasons why this might occur. If your fluid level is low, your engine will not circulate enough antifreeze to fill your heater core ( which usually leads to your engine overheating, but not always if you are just borderline low), if your heater core is plugged (most common) or if you have a sealed system and there is air in the system which prevents your liquidfrom running through the heater core. The most likely cause is a bad heater core which is bad news because it is hard to access, therefor hard to replace.
did the heater core start leaking? anyway you should have no problem with the air if you bypass the heater core.
Not necessarily. It depends on what you mean by a bad heater core. The core will either be leaking or stopped up. If it is leaking, then it can cause the engine to overheat and the only fix is to replace it. A clogged or plugged heater core can sometimes be fixed by flushing it. You can also temporarily bypass the heater core until you can get it fixed. Just connect the inlet & outlet heater hoses together.
The block heater, on your 2001 C 15 Caterpillar diesel engine, can be removed by loosening the retaining nut. The block heater will easily come out. Reverse the process to install the new heater.
There are hoses in the engine compartment that go to the heater core. You can remove the intake and out going hoses from the heater core. You have to either block off these hoses or connect them together, depending on the make of the vehicle.
