SOURCE: replaced the heater core. now i cant get good heat

When u put the heater core back either you mixed up the A/c controls with the heater control, or the gate that allows air across you heat ex. is not opening.
Feel the temperature of the water going in and out of the heat ex. (open the hood and feel down by the firewall where the pipes go thru)

If it isnt hot going in there is a valve problem not allowing water to circulate.
If both are hot, then the blower gate isnt opening or the A/c control is confused with the heater control. ( a bit unlikely)
Hope that helps

SOURCE: How do replace heater core in 2002 Pontiac Gran Prix

i do believe you have to take the passengers side dash apart behind the glove compartment. go to autozone and get a manual or go to the library and check the chiltons manual. this is not an easy job. how bad is the leak? if its not bad these heater cores are made of all aluminum. i would buy a bottle of that radiator additive and see if that takes care of the problem first. it only cost about 5 bucks a bottle and it may permanantly fix your problem.

SOURCE: Have to replace the heater core on a 1997 Pot.

This is a fairly easy fix. Disconnect the heater hoses under the hood. Go to passenger side under the dash remove the lower panel from the dash to access the heater box. Unplug any and all connections on the lower half of the heater box and remove the lower half of the box should be about six screws you should see the heater core and the evaporator core. Heater core skinnier of the two should have one or two straps holding it in remove the straps and remove the core and replace.

SOURCE: had to replace water pump

You may have loosened or lost some material into the system while changing the pump and caused a blockage in the heater core. There could be a little coolant going through to warm up but not enough to continue supplying heat once the initial heat is drawn down.
Ideally a back flush through the heater core may take care of it. You should be able to find a kit to help with in an auto parts store.
Open the hood and look on the firewall of the car. There should be 2 rubber hoses going into the firewall and into the car. They will likely have spring clamps just like on the radiator hose. Remove both lines. Then get a hose and put it in one line and run the water until it comes out clear. Then do the same thing with the other side. Do this a couple of times. Then reconnect the 2 hoses ahd check the level of the radiator. Then start the car with the radiator cap off and wait a while for the thermostat to open and have the heater on so it will cycle through the whole system. Then top off as needed.

I am looking for the location the heater core on the van

You didnt list the year make and model of the van but all heatercores are located inside the heater box. depending on the year and model there are some where the dash must be removed inorder to gain acess to replace the core, and some there are panels you can remove and then take heater box apart without removing the dash to gain acess to core. good day. heres a picture to help explain where the heatercore is .this would be inside the van on the pass/side under dash. good day.johnjohn2_154.gif

I notice that there is not an inlet water value from the thermostat to the heater core on my 2000 Chevrolet Silverado 1500 engine is a 5.3 but I notice heater hose is hot and one is cold for the heater...

I have seen dexcool( orange coolant ) clog many things.If it was mine i would take notice of which side is cool and remove hoses and take garden hose and flush it out in reverse.In other words push water in from the cool side in the oposite direction that it normally flows.It worked on my 2001 buick.

I have a 1999 jeep grand cheroke my heater core is leaking I try stop leak it doesn't work any other option instead replace my heatercore??

I would just have the heater core replaced. One common theme with all repairs that are temporary, is ... well, "temporary" can mean "all of three seconds". All the stop leak gunk and whatnot will typically block your heater core up, making you replace it anyway if you want heat. Or you could take the heater core out of the loop, get an adaptor and plumb the heater lines together.
