Need to back flush heater core on 1999 dodge stratus where is hoses located

Heater cores are being made with such small tube/passages that small specks of rust, dirt, bugs, anything that may be traveling around inside your engine with the coolant, sticks to the heater core. Lately, I have been calling heater cores "coolant strainers". Ha Ha. Here is what you do. Take the heater hoses off (at the engine). Push water through both ways. Chase that water with some air pressure. This will blast all debris from the core. Hook up the hoses, fill the coolant to the proper level, and POW you have heat.

Right think the problem is the heater core is blocked with corrosion ,now remove the bottom hose from the rad and the heater hoses then flush every which way you can including through the heater core reversing direction then ,refit all the hoses fill with water only and see if heater works if so the remove the bottom hose again and drain ,then add a minium of 3 litres of antifreeze ,its a anti corrosion agent as well as antifreeze and without it the internal of the engine will corrode and the slurry will block the heater first then the radiator ,

remove the heater hoses (both, unless you want to flush it into the radiator, just kidding) hook up (auto parts shop will have a coolant flush kit to hook up to the heater hoses) a garden hose and turn it on, flush both ways.

thats where your problem lies at... take both hoses off and back flush the heater core, till water runs freely through it.

Remove both heater hoses from motor. Put your garden hose in one end and tape on securely with the other end pointing in a direction the water flow from it will not hit distributor or other vital electronics. Turn on hose - If water come out of heater core at same rate as you are pumping it in then your heater core is flowing - if not then your core is blocked or plugged. Be mindful - if the core is plugged the water will break the seal of the garden hose and heater hose, spraying everywhere, so turn the water on low to check and be ready to shut off quickly!!

is the thermostat stuck open?  You will see two hoses going to the firewall.  These are the heater hoses.

Seems like the heater core is possibly plugged. I would try flushing the heater core before changing it. Look in the engine compartment on the cars right side. Find where two cooling line go into the firewall. Roughly 1" - 1 1/2" in size. Disconnect these lines. You will loose fluid, so put a container under the car. Use a garden hose and flush the core in one side and make sure the water flows out the other. Then repeat this process to flush the opposite way. If the water does not flow easily, then there is something stuck inside the core, then it will have to be replaced.

The coolant thermostat needs replaced or you need a coolant flush. Heater cores (in the dashboard) often clog and stop warm coolant from circulating into the heater. A coolant flush would cure this. Flushes usually run from 70 to 90 dollars to have done at a service shop.
