The heater core is located on the passenger side of the vehicle. If this has been bypass the core is surely leaking. The heater core pipes should be visible from un der the hood, passenger side of vehicle towards the firewall. keep me posted, and keep an eye on that heater core, there is reason for the prior owner not to have heat.

Heater doesnt work but ac does


Assuming the fan blows OK but you have no heat. Go to the firewall and notice where the heater hoses enter and exit the cabin. You'll notice a metal manifold and also a rubber bypass hose that connects the two. This bypass hose is a design problem and causes the coolant to bypass the heater core which is located inside the cabin under the dash. Over time, the heater core gets blocked by gunk and you'll get no heat. All the coolant flows through the bypass hose when this happens. The fix is to flush the heater core itself. It's difficult to access at the firewall, so I disconnect the two hoses at the engine itself and attach a garden hose to flush it. Before doing this you must clamp (vice grips) the bypass hose so that all of the water goes through the heater core.

Heater core bypass


you will not have any heat at all ! so do this. remove the hoses. on firewall side to heater core. go to any auto parts store and buy a coolant flush kit, then use the right size tube to hook hoses back together and clamp them. recheck coolant and that should be it. good-day !

Had heater disconnected...need to hook it back up. anyone know how?


There are two heater hoses, each appx. 1 inch wide, that run from the engine and hooks up to the heater core, behind your dashboard. The heater core's two connection pipes stick out from the firewall of your jeep and you have to attach the two heater hoses to those two pipes. If someone disconnected your heater, they probably just joined together the two heater hoses, that run from your engine, so now you'll have to disconnect that joining and reattach the hoses to the heater core pipes. That way, hot coolant will flow into the heater core to warm you up.

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 !

The heater core in a 97 cougar i just bought has been bypassed. Could the problem have possibly (hopefully) been something else besides the heater core?


Hi,
The answer is: Your first instinct is probably right. But, you're not going to know for sure until you hook it back up and check it out. Be careful, check for leaks inside and out of the car. You don't want to end up with more problems than you have now.
Hope this Helps,

Have had the same problem with a Corsica.The reason they bypassed the heater core is that it had a hole in it.Reccomend filling with water prior to hooking up hoses.

No heat in 2000 chevy lazer just replaced thermostat


I own a 200 Chevrolet Blazer and I have it for over 4 years mine does the same thing I actually just noticed my heat getting less. My husband found the best way to fix it and the cheapest way to fix it. He takes the tube off the heater and attaches a water hose to it and flushes out the gunk whatever is blocking the hose and after he does that the heat works great. No cost and if I wanted to I could do it because its so easy. My husband did some searching on the internet and a person that this happens all the time to let me husband know. If you need more info let me know I can ask my husband he isn't home at the moment I so I don't have exact details. Thanks Amy
