There should be a plug sticking out of or near the front grill. Block heaters are generally connected to the oil pan.
If you meant the heat exchange that brings heat from the engine into the passenger area, that is on the psssenger side betwern the firewall and the dashboard, usually near the glove compartment. This heater core will leak sweet-smelling radiator fluid (engine coolant) onto thr floorboards if it is defective. If you just aren't getting heat, be sure your coolant level is full, and if it is (but there is no leaking into the passenger area,) then look at the valve inside the engine compartment, and at what is called the Blend-door.

Cant find a block heater for an 06 Elantra


Very likely both engines use the same block heater. It should tell on the application chart with the block heater.

Need to know where my Heater Core hoses hook up to on the engine? I see the Hoses but is there a seperate part that the hose connects to?


The best way to locate a heater core hose is to determine where the heater core is located. Many vehicles have the heater core inside the dash. Other vehicles, usually larger vans and trucks, will have a heater core box inside the engine compartment. Once you have determined where the heater core is located in your vehicle, that will allow you to easily locate a heater core hose. If the heater core is inside the dash, you'll need to examine the firewall for the hoses. If it is in a heater box, you'll need to look around the engine compartment for the box.




Heater cores located inside dashes can be very difficult and time consuming to replace. Depending on the layout of your engine compartment, it can also be difficult to locate a heater core hose. If there is very little clearance between the engine and the firewall, you may have difficulty finding the hoses. You might need to use a flashlight to look from the underside in some cases. You will typically be able to identify the heater hoses where they enter the firewall by looking for two two small diameter hoses that protrude into the engine compartment. You can then trace those hoses to their other ends, where they will typically connect to a thermostat housing, the radiator, or a t-connector.


Hope this helps.

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

How do you bypass a heater core on the 2000 Chevy Venture. It has a rear and a front heater core with a 3 way T outlet connecting several hoses and more than two hoses that go into the firewall since it...


Yes it can be done. look at your engine on it there will be two heater hoses coming from the engine to the heater, disconnect those two heater hoses at engine, with heater hose and two hose clamps, get the hose and clamp first at auto parts, install one end and the other end of same hose, where you disconnected the heater hoses from the engine, you have just by-pass the heater, hope this was very helpful.

When you bypass the heater core the path for the water to go through the core is gone. Correct?, you have connected to engine water line out to the engine water input? thus bypassing the heater core........


No, you just won't have water flow through the heater core, Coolant flows through the engine through the lower radiator hose as the water pump sucks it out of the radiator and pushes it through the engine. It then flows out the top radiator hose when the thermostat opens. It then flows into the radiator to cool off.

Is your heater core leaking?

Heater problem


is your heater set on defrost this will cause your engine fan to run because it turns on the compressor for air conditioner this helps to extract moisture from your warm air defrost  and the fan in the engine compartment helps keep it the engine cool from the extra load on the engine this is normal

  1. Drain the engine coolant into a suitable container.
  2. Open the instrument panel glove compartment. Push in on the sides of the compartment to release it, allowing access to the heater core.
The heater core can be damaged if too much force is applied to the heater core pipes during hose removal.
  1. Remove the heater module screws and remove the heater module assembly cover. For vehicles equipped with A/C, remove the air conditioning evaporator temperature sensor assembly from the heater and A/C cover.
  2. Remove the heater core screw and clamp.
  3. Remove the hose pipe clamp screw and the hose pipe clamp. Clamp off the heater hoses.

  1. Disconnect the heater hoses from the pipes.
  2. Remove the heater core by carefully pulling it towards you.
0900c152800b8724.jpgFig. 4: Exploded view of the heater core removed from the heater module assemblyTo install:
  1. Install the heater core and attach the heater hose assembly to the heater hose pipes. Note the following:
    1. Lubricate the heater core pipes with petroleum jelly for ease of installation and to assure a good seal.
    2. Be sure the seals around the heater pipes remain in place when installing.
    3. To verify that the seal is installed correctly, observe the seal from inside the engine compartment. If the seal has leaks, apply a sealer between the heater core pipes and the evaporator housing.
  2. Install the hose pipe clamp and the bolt/screw. Unclamp the heater hoses. Tighten the hose pipe clamp bolt/screw to 16 inch lbs. (1.8 Nm).
  3. Install the heater core clamp and screw. Tighten the screw to 16 inch lbs. (1.8 Nm).
  4. Install the heater module assembly cover and secure with the retaining screws. Tighten the screws to 18 inch lbs. (2 Nm).
  5. Connect the negative battery cable.
  6. Refill the cooling system. Operate the engine and check for leaks, add coolant if necessary.
  7. Install the instrument panel glove compartment.

Heater is weak


a couple likely causes:
1: the engines thermostat is stuck open preventing the engine from warming up quickly. If the engine temps read normal (warm) but the heater is still cool, then....
2. the Heater control valve (a valve that prevent hot water flow when you dont want it), may be clogged or malfunctioning. this is typically located on the heater hoses between engine and firewall.
